-INTRODUCTION TO ARCNET
-----------------------
-
-ARCnet is a network type which works in a way similar to popular Ethernet
-networks but which is also different in some very important ways.
-
-First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps
-(slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact,
-there are others as well, but these are less common. The different hardware
-types, as far as I'm aware, are not compatible and so you cannot wire a
-100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does
-work with 100 Mbps cards, but I haven't been able to verify this myself,
-since I only have the 2.5 Mbps variety. It is probably not going to saturate
-your 100 Mbps card. Stop complaining. :)
-
-You also cannot connect an ARCnet card to any kind of Ethernet card and
-expect it to work.
-
-There are two "types" of ARCnet - STAR topology and BUS topology. This
-refers to how the cards are meant to be wired together. According to most
-available documentation, you can only connect STAR cards to STAR cards and
-BUS cards to BUS cards. That makes sense, right? Well, it's not quite
-true; see below under "Cabling."
-
-Once you get past these little stumbling blocks, ARCnet is actually quite a
-well-designed standard. It uses something called "modified token passing"
-which makes it completely incompatible with so-called "Token Ring" cards,
-but which makes transfers much more reliable than Ethernet does. In fact,
-ARCnet will guarantee that a packet arrives safely at the destination, and
-even if it can't possibly be delivered properly (ie. because of a cable
-break, or because the destination computer does not exist) it will at least
-tell the sender about it.
-
-Because of the carefully defined action of the "token", it will always make
-a pass around the "ring" within a maximum length of time. This makes it
-useful for realtime networks.
-
-In addition, all known ARCnet cards have an (almost) identical programming
-interface. This means that with one ARCnet driver you can support any
-card, whereas with Ethernet each manufacturer uses what is sometimes a
-completely different programming interface, leading to a lot of different,
-sometimes very similar, Ethernet drivers. Of course, always using the same
-programming interface also means that when high-performance hardware
-facilities like PCI bus mastering DMA appear, it's hard to take advantage of
-them. Let's not go into that.
-
-One thing that makes ARCnet cards difficult to program for, however, is the
-limit on their packet sizes; standard ARCnet can only send packets that are
-up to 508 bytes in length. This is smaller than the Internet "bare minimum"
-of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra
-level of encapsulation is defined by RFC1201, which I call "packet
-splitting," that allows "virtual packets" to grow as large as 64K each,
-although they are generally kept down to the Ethernet-style 1500 bytes.
-
-For more information on the advantages and disadvantages (mostly the
-advantages) of ARCnet networks, you might try the "ARCnet Trade Association"

-CABLING ARCNET NETWORKS
------------------------
-
-This section was rewritten by
- Vojtech Pavlik <vojtech@suse.cz>
-using information from several people, including:
- Avery Pennraun <apenwarr@worldvisions.ca>
- Stephen A. Wood <saw@hallc1.cebaf.gov>
- John Paul Morrison <jmorriso@bogomips.ee.ubc.ca>
- Joachim Koenig <jojo@repas.de>
-and Avery touched it up a bit, at Vojtech's request.
-
-ARCnet (the classic 2.5 Mbps version) can be connected by two different
-types of cabling: coax and twisted pair. The other ARCnet-type networks
-(100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
-cabling (Type1, Fiber, C1, C4, C5).
-
-For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
-also work fine, because ARCnet is a very stable network. I personally use 75
-Ohm TV antenna cable.
-
-Cards for coax cabling are shipped in two different variants: for BUS and
-STAR network topologies. They are mostly the same. The only difference
-lies in the hybrid chip installed. BUS cards use high impedance output,
-while STAR use low impedance. Low impedance card (STAR) is electrically
-equal to a high impedance one with a terminator installed.
-
-Usually, the ARCnet networks are built up from STAR cards and hubs. There
-are two types of hubs - active and passive. Passive hubs are small boxes
-with four BNC connectors containing four 47 Ohm resistors:
-
- | | wires
- R + junction
--R-+-R- R 47 Ohm resistors
- R
- |
-
-The shielding is connected together. Active hubs are much more complicated;
-they are powered and contain electronics to amplify the signal and send it
-to other segments of the net. They usually have eight connectors. Active
-hubs come in two variants - dumb and smart. The dumb variant just
-amplifies, but the smart one decodes to digital and encodes back all packets
-coming through. This is much better if you have several hubs in the net,
-since many dumb active hubs may worsen the signal quality.
-
-And now to the cabling. What you can connect together:
-
-1. A card to a card. This is the simplest way of creating a 2-computer
- network.
-
-2. A card to a passive hub. Remember that all unused connectors on the hub
- must be properly terminated with 93 Ohm (or something else if you don't
- have the right ones) terminators.
- (Avery's note: oops, I didn't know that. Mine (TV cable) works
- anyway, though.)
-
-3. A card to an active hub. Here is no need to terminate the unused
- connectors except some kind of aesthetic feeling. But, there may not be
- more than eleven active hubs between any two computers. That of course
- doesn't limit the number of active hubs on the network.
-
-4. An active hub to another.
-
-5. An active hub to passive hub.
-
-Remember that you cannot connect two passive hubs together. The power loss
-implied by such a connection is too high for the net to operate reliably.
-
-An example of a typical ARCnet network:
-
- R S - STAR type card
- S------H--------A-------S R - Terminator
- | | H - Hub
- | | A - Active hub
- | S----H----S
- S |
- |
- S
-
-The BUS topology is very similar to the one used by Ethernet. The only
-difference is in cable and terminators: they should be 93 Ohm. Ethernet
-uses 50 Ohm impedance. You use T connectors to put the computers on a single
-line of cable, the bus. You have to put terminators at both ends of the
-cable. A typical BUS ARCnet network looks like:
-
- RT----T------T------T------T------TR
- B B B B B B
-
- B - BUS type card
- R - Terminator
- T - T connector
-
-But that is not all! The two types can be connected together. According to
-the official documentation the only way of connecting them is using an active
-hub:
-
- A------T------T------TR
- | B B B
- S---H---S
- |
- S
-
-The official docs also state that you can use STAR cards at the ends of
-BUS network in place of a BUS card and a terminator:
-
- S------T------T------S
- B B
-
-But, according to my own experiments, you can simply hang a BUS type card
-anywhere in middle of a cable in a STAR topology network. And more - you
-can use the bus card in place of any star card if you use a terminator. Then
-you can build very complicated networks fulfilling all your needs! An
-example:
-
- S
- |
- RT------T-------T------H------S
- B B B |
- | R
- S------A------T-------T-------A-------H------TR
- | B B | | B
- | S BT |
- | | | S----A-----S
- S------H---A----S | |
- | | S------T----H---S |
- S S B R S
-
-A basically different cabling scheme is used with Twisted Pair cabling. Each
-of the TP cards has two RJ (phone-cord style) connectors. The cards are
-then daisy-chained together using a cable connecting every two neighboring
-cards. The ends are terminated with RJ 93 Ohm terminators which plug into
-the empty connectors of cards on the ends of the chain. An example:
-
- ___________ ___________
- _R_|_ _|_|_ _|_R_
- | | | | | |
- |Card | |Card | |Card |
- |_____| |_____| |_____|
-
-
-There are also hubs for the TP topology. There is nothing difficult
-involved in using them; you just connect a TP chain to a hub on any end or
-even at both. This way you can create almost any network configuration.
-The maximum of 11 hubs between any two computers on the net applies here as
-well. An example:
-
- RP-------P--------P--------H-----P------P-----PR
- |
- RP-----H--------P--------H-----P------PR
- | |
- PR PR
-
- R - RJ Terminator
- P - TP Card
- H - TP Hub
-
-Like any network, ARCnet has a limited cable length. These are the maximum
-cable lengths between two active ends (an active end being an active hub or
-a STAR card).
-
- RG-62 93 Ohm up to 650 m
- RG-59/U 75 Ohm up to 457 m
- RG-11/U 75 Ohm up to 533 m
- IBM Type 1 150 Ohm up to 200 m
- IBM Type 3 100 Ohm up to 100 m
-
-The maximum length of all cables connected to a passive hub is limited to 65
-meters for RG-62 cabling; less for others. You can see that using passive
-hubs in a large network is a bad idea. The maximum length of a single "BUS
-Trunk" is about 300 meters for RG-62. The maximum distance between the two
-most distant points of the net is limited to 3000 meters. The maximum length
-of a TP cable between two cards/hubs is 650 meters.
-
-
-SETTING THE JUMPERS
--------------------
-
-All ARCnet cards should have a total of four or five different settings:
-
- - the I/O address: this is the "port" your ARCnet card is on. Probed
- values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
- your card has additional ones, which is possible, please tell me.) This
- should not be the same as any other device on your system. According to
- a doc I got from Novell, MS Windows prefers values of 0x300 or more,
- eating net connections on my system (at least) otherwise. My guess is
- this may be because, if your card is at 0x2E0, probing for a serial port
- at 0x2E8 will reset the card and probably mess things up royally.
- - Avery's favourite: 0x300.
-
- - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
- on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
-
- Make sure this is different from any other card on your system. Note
- that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can
- "cat /proc/interrupts" for a somewhat complete list of which ones are in
- use at any given time. Here is a list of common usages from Vojtech
- Pavlik <vojtech@suse.cz>:
- ("Not on bus" means there is no way for a card to generate this
- interrupt)
- IRQ 0 - Timer 0 (Not on bus)
- IRQ 1 - Keyboard (Not on bus)
- IRQ 2 - IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
- IRQ 3 - COM2
- IRQ 4 - COM1
- IRQ 5 - FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
- IRQ 6 - Floppy disk controller
- IRQ 7 - FREE (LPT1 if you don't use the polling driver; PLIP)
- IRQ 8 - Realtime Clock Interrupt (Not on bus)
- IRQ 9 - FREE (VGA vertical sync interrupt if enabled)
- IRQ 10 - FREE
- IRQ 11 - FREE
- IRQ 12 - FREE
- IRQ 13 - Numeric Coprocessor (Not on bus)
- IRQ 14 - Fixed Disk Controller
- IRQ 15 - FREE (Fixed Disk Controller 2 if you have it)
-
- Note: IRQ 9 is used on some video cards for the "vertical retrace"
- interrupt. This interrupt would have been handy for things like
- video games, as it occurs exactly once per screen refresh, but
- unfortunately IBM cancelled this feature starting with the original
- VGA and thus many VGA/SVGA cards do not support it. For this
- reason, no modern software uses this interrupt and it can almost
- always be safely disabled, if your video card supports it at all.
-
- If your card for some reason CANNOT disable this IRQ (usually there
- is a jumper), one solution would be to clip the printed circuit
- contact on the board: it's the fourth contact from the left on the
- back side. I take no responsibility if you try this.
-
- - Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
-
- - the memory address: Unlike most cards, ARCnets use "shared memory" for
- copying buffers around. Make SURE it doesn't conflict with any other
- used memory in your system!
- A0000 - VGA graphics memory (ok if you don't have VGA)
- B0000 - Monochrome text mode
- C0000 \ One of these is your VGA BIOS - usually C0000.
- E0000 /
- F0000 - System BIOS
-
- Anything less than 0xA0000 is, well, a BAD idea since it isn't above
- 640k.
- - Avery's favourite: 0xD0000
-
- - the station address: Every ARCnet card has its own "unique" network
- address from 0 to 255. Unlike Ethernet, you can set this address
- yourself with a jumper or switch (or on some cards, with special
- software). Since it's only 8 bits, you can only have 254 ARCnet cards
- on a network. DON'T use 0 or 255, since these are reserved (although
- neat stuff will probably happen if you DO use them). By the way, if you
- haven't already guessed, don't set this the same as any other ARCnet on
- your network!
- - Avery's favourite: 3 and 4. Not that it matters.
-
- - There may be ETS1 and ETS2 settings. These may or may not make a
- difference on your card (many manuals call them "reserved"), but are
- used to change the delays used when powering up a computer on the
- network. This is only necessary when wiring VERY long range ARCnet
- networks, on the order of 4km or so; in any case, the only real
- requirement here is that all cards on the network with ETS1 and ETS2
- jumpers have them in the same position. Chris Hindy <chrish@io.org>
- sent in a chart with actual values for this:
- ET1 ET2 Response Time Reconfiguration Time
- --- --- ------------- --------------------
- open open 74.7us 840us
- open closed 283.4us 1680us
- closed open 561.8us 1680us
- closed closed 1118.6us 1680us
-
- Make sure you set ETS1 and ETS2 to the SAME VALUE for all cards on your
- network.
-
-Also, on many cards (not mine, though) there are red and green LED's.
-Vojtech Pavlik <vojtech@suse.cz> tells me this is what they mean:
- GREEN RED Status
- ----- --- ------
- OFF OFF Power off
- OFF Short flashes Cabling problems (broken cable or not
- terminated)
- OFF (short) ON Card init
- ON ON Normal state - everything OK, nothing
- happens
- ON Long flashes Data transfer
- ON OFF Never happens (maybe when wrong ID)
-
-
-The following is all the specific information people have sent me about
-their own particular ARCnet cards. It is officially a mess, and contains
-huge amounts of duplicated information. I have no time to fix it. If you
-want to, PLEASE DO! Just send me a 'diff -u' of all your changes.
-
-The model # is listed right above specifics for that card, so you should be
-able to use your text viewer's "search" function to find the entry you want.
-If you don't KNOW what kind of card you have, try looking through the
-various diagrams to see if you can tell.
-
-If your model isn't listed and/or has different settings, PLEASE PLEASE
-tell me. I had to figure mine out without the manual, and it WASN'T FUN!
-
-Even if your ARCnet model isn't listed, but has the same jumpers as another
-model that is, please e-mail me to say so.

-Switches 4-6 of switch group S1 select the Base of the 16K block.
-Within that 16K address space, the buffer may be assigned any one of four
-positions, determined by the offset, switches 7 and 8 of group S1.

-*) To enable the 8K Boot PROM install the jumper ROM.
- The default is jumper ROM not installed.
-
-
-Setting the Timeouts and Interrupt
-----------------------------------
-
-The jumpers labeled EXT1 and EXT2 are used to determine the timeout
-parameters. These two jumpers are normally left open.
-
-To select a hardware interrupt level set one (only one!) of the jumpers
-IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.
-
-
-Configuring the PC130E for Star or Bus Topology
------------------------------------------------
-
-The single jumper labeled STAR is used to configure the PC130E board for
-star or bus topology.
-When the jumper is installed, the board may be used in a star network, when
-it is removed, the board can be used in a bus topology.
-
-
-Diagnostic LEDs
----------------
-
-Two diagnostic LEDs are visible on the rear bracket of the board.
-The green LED monitors the network activity: the red one shows the
-board activity:

-STANDARD MICROSYSTEMS CORPORATION (SMC) ARCNET-PC500/PC550 Long Board
-=====================================================================
-
-Note: There is another Version of the PC500 called Short Version, which
- is different in hard- and software! The most important differences
- are:
- - The long board has no Shared memory.
- - On the long board the selection of the interrupt is done by binary
- coded switch, on the short board directly by jumper.
-
-[Avery's note: pay special attention to that: the long board HAS NO SHARED
-MEMORY. This means the current Linux-ARCnet driver can't use these cards.
-I have obtained a PC500Longboard and will be doing some experiments on it in
-the future, but don't hold your breath. Thanks again to Juergen Seifert for
-his advice about this!]

-
-Setting one of the switches to Off/Open means "1", On/Closed means "0".
-
-
-Setting the Node ID
--------------------
-
-The eight switches in group SW3 are used to set the node ID. Each node
-attached to the network must have an unique node ID which must be
-different from 0.
-Switch 1 serves as the least significant bit (LSB).
-
-The node ID is the sum of the values of all switches set to "1"
-These values are:
-
- Switch | Value
- -------|-------
- 1 | 1
- 2 | 2
- 3 | 4
- 4 | 8
- 5 | 16
- 6 | 32

-Setting the I/O Base Address
-----------------------------
-
-The first six switches in switch group SW1 are used to select one
-of 32 possible I/O Base addresses using the following table
-
- Switch | Hex I/O
- 6 5 4 3 2 1 | Address
- -------------|--------
- 0 1 0 0 0 0 | 200
- 0 1 0 0 0 1 | 210

-
-Setting the Interrupt
----------------------
-
-Switches seven through ten of switch group SW1 are used to select the
-interrupt level. The interrupt level is binary coded, so selections
-from 0 to 15 would be possible, but only the following eight values will
-be supported: 3, 4, 5, 7, 9, 10, 11, 12.
-
- Switch | IRQ
- 10 9 8 7 |
- ---------|--------
- 0 0 1 1 | 3
- 0 1 0 0 | 4
- 0 1 0 1 | 5
- 0 1 1 1 | 7
- 1 0 0 1 | 9 (=2) (default)
- 1 0 1 0 | 10
- 1 0 1 1 | 11
- 1 1 0 0 | 12
-
-
-Setting the Timeouts
---------------------
-
-The two jumpers JP2 (1-4) are used to determine the timeout parameters.
-These two jumpers are normally left open.
-Refer to the COM9026 Data Sheet for alternate configurations.
-
-
-Configuring the PC500 for Star or Bus Topology
-----------------------------------------------
-
-The single jumper labeled JP6 is used to configure the PC500 board for
-star or bus topology.
-When the jumper is installed, the board may be used in a star network, when
-it is removed, the board can be used in a bus topology.
-
-
-Diagnostic LEDs
----------------
-
-Two diagnostic LEDs are visible on the rear bracket of the board.
-The green LED monitors the network activity: the red one shows the
-board activity:
-
- Green | Status Red | Status
- -------|------------------- ---------|-------------------
- on | normal activity flash/on | data transfer
- blink | reconfiguration off | no data transfer;
- off | defective board or | incorrect memory or
- | node ID is zero | I/O address

-PC710 (8-bit card)
-------------------
- - from J.S. van Oosten <jvoosten@compiler.tdcnet.nl>
-
-Note: this data is gathered by experimenting and looking at info of other
-cards. However, I'm sure I got 99% of the settings right.
-
-The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
-LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing:

-
-The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
-labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
-IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
-
-S1 and S2 perform the same function as on the PC270, only their numbers
-are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
-
-I know it works when connected to a PC110 type ARCnet board.

-LCS-8830(-T) (8 and 16-bit cards)
----------------------------------
- - from Mathias Katzer <mkatzer@HRZ.Uni-Bielefeld.DE>
- - Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl> says the
- LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS
- only (the JP0 jumper is hardwired), and BNC only.
-
-This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
-nowhere else, not even on the few Xeroxed sheets from the manual).

-PDI507 (8-bit card)
---------------------
- - from Mark Rejhon <mdrejhon@magi.com> (slight modifications by Avery)
- - Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
- are mostly the same as this. PDI508Plus cards appear to be mainly
- software-configured.
-
-Jumpers:
- There is a jumper array at the bottom of the card, near the edge
- connector. This array is labelled J1. They control the IRQs and
- something else. Put only one jumper on the IRQ pins.
-
- ETS1, ETS2 are for timing on very long distance networks. See the
- more general information near the top of this file.
-
- There is a J2 jumper on two pins. A jumper should be put on them,
- since it was already there when I got the card. I don't know what
- this jumper is for though.
-
- There is a two-jumper array for J3. I don't know what it is for,
- but there were already two jumpers on it when I got the card. It's
- a six pin grid in a two-by-three fashion. The jumpers were
- configured as follows:
-
- .-------.
- o | o o |
- :-------: ------> Accessible end of card with connectors
- o | o o | in this direction ------->
- `-------'
-
-Carl de Billy <CARL@carainfo.com> explains J3 and J4:

-
- - If using coax cable in a bus topology the J4 jumper must be removed;
- place it on one pin.
-
- - If using bus topology with twisted pair wiring move the J3
- jumpers so they connect the middle pin and the pins closest to the RJ11
- Connectors. Also the J4 jumper must be removed; place it on one pin of
- J4 jumper for storage.
-
- - If using star topology with twisted pair wiring move the J3
- jumpers so they connect the middle pin and the pins closest to the RJ11
- connectors.
-
-
-DIP Switches:
-
- The DIP switches accessible on the accessible end of the card while
- it is installed, is used to set the ARCnet address. There are 8
- switches. Use an address from 1 to 254.
-
- Switch No.
- 12345678 ARCnet address
- -----------------------------------------
- 00000000 FF (Don't use this!)
- 00000001 FE
- 00000010 FD
- ....
- 11111101 2
- 11111110 1
- 11111111 0 (Don't use this!)
-
- There is another array of eight DIP switches at the top of the
- card. There are five labelled MS0-MS4 which seem to control the
- memory address, and another three labelled IO0-IO2 which seem to
- control the base I/O address of the card.
-
- This was difficult to test by trial and error, and the I/O addresses
- are in a weird order. This was tested by setting the DIP switches,
- rebooting the computer, and attempting to load ARCETHER at various
- addresses (mostly between 0x200 and 0x400). The address that caused
- the red transmit LED to blink, is the one that I thought works.
-
- Also, the address 0x3D0 seem to have a special meaning, since the
- ARCETHER packet driver loaded fine, but without the red LED
- blinking. I don't know what 0x3D0 is for though. I recommend using
- an address of 0x300 since Windows may not like addresses below
- 0x300.
-
- IO Switch No.
- 210 I/O address
- -------------------------------
- 111 0x260
- 110 0x290
- 101 0x2E0
- 100 0x2F0
- 011 0x300
- 010 0x350
- 001 0x380
- 000 0x3E0
-
- The memory switches set a reserved address space of 0x1000 bytes
- (0x100 segment units, or 4k). For example if I set an address of
- 0xD000, it will use up addresses 0xD000 to 0xD100.
-
- The memory switches were tested by booting using QEMM386 stealth,
- and using LOADHI to see what address automatically became excluded
- from the upper memory regions, and then attempting to load ARCETHER
- using these addresses.
-
- I recommend using an ARCnet memory address of 0xD000, and putting
- the EMS page frame at 0xC000 while using QEMM stealth mode. That
- way, you get contiguous high memory from 0xD100 almost all the way
- the end of the megabyte.
-
- Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
- on my card. It could be malfunctioning on my card. Experiment with
- it ON first, and if it doesn't work, set it to OFF. (It may be a
- modifier for the 0x200 bit?)
-
- MS Switch No.
- 43210 Memory address
- --------------------------------
- 00001 0xE100 (guessed - was not detected by QEMM)
- 00011 0xE000 (guessed - was not detected by QEMM)
- 00101 0xDD00
- 00111 0xDC00
- 01001 0xD900
- 01011 0xD800
- 01101 0xD500
- 01111 0xD400
- 10001 0xD100
- 10011 0xD000
- 10101 0xCD00
- 10111 0xCC00
- 11001 0xC900 (guessed - crashes tested system)
- 11011 0xC800 (guessed - crashes tested system)

-
-
-Setting the Node ID
--------------------
-
-The eight switches in SW2 are used to set the node ID. Each node attached
-to the network must have an unique node ID which must be different from 0.
-Switch 1 (ID0) serves as the least significant bit (LSB).
-
-The node ID is the sum of the values of all switches set to "1"
-These values are:
-
- Switch | Label | Value
- -------|-------|-------
- 1 | ID0 | 1
- 2 | ID1 | 2
- 3 | ID2 | 4
- 4 | ID3 | 8
- 5 | ID4 | 16
- 6 | ID5 | 32
- 7 | ID6 | 64
- 8 | ID7 | 128
-
-Some Examples:
-
- Switch | Hex | Decimal
- 8 7 6 5 4 3 2 1 | Node ID | Node ID
- ----------------|---------|---------

- 1 1 1 1 1 1 1 1 | FF | 255
-
-
-Setting the I/O Base Address
-----------------------------
-
-The last three switches in switch block SW1 are used to select one
-of eight possible I/O Base addresses using the following table
-
-
- Switch | Hex I/O
- 6 7 8 | Address
- ------------|--------
- ON ON ON | 260
- OFF ON ON | 290
- ON OFF ON | 2E0 (Manufacturer's default)
- OFF OFF ON | 2F0
- ON ON OFF | 300
- OFF ON OFF | 350
- ON OFF OFF | 380
- OFF OFF OFF | 3E0
-
-
-Setting the Base Memory (RAM) buffer Address
---------------------------------------------
-
-The memory buffer (RAM) requires 2K. The base of this buffer can be
-located in any of eight positions. The address of the Boot Prom is
-memory base + 8K or memory base + 0x2000.
-Switches 1-5 of switch block SW1 select the Memory Base address.
-
- Switch | Hex RAM | Hex ROM
- 1 2 3 4 5 | Address | Address *)
- --------------------|---------|-----------
- ON ON ON ON ON | C0000 | C2000
- ON ON OFF ON ON | C4000 | C6000
- ON ON ON OFF ON | CC000 | CE000
- ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
- ON ON ON ON OFF | D4000 | D6000
- ON ON OFF ON OFF | D8000 | DA000
- ON ON ON OFF OFF | DC000 | DE000
- ON ON OFF OFF OFF | E0000 | E2000
-
-*) To enable the Boot ROM install the jumper JP1
-
-Note: Since the switches 1 and 2 are always set to ON it may be possible
- that they can be used to add an offset of 2K, 4K or 6K to the base
- address, but this feature is not documented in the manual and I
- haven't tested it yet.
-
-
-Setting the Interrupt Line
---------------------------
-
-To select a hardware interrupt level install one (only one!) of the jumpers
-JP2, JP3, JP4, JP5, JP6. JP2 is the default.
-

-
-Note: Other IO-Base addresses seem to be selectable, but only the above
- combinations are documented.
-
-
-Setting the Base Memory (RAM) buffer Address
---------------------------------------------
-
-The switches 7-10 of switch block SW1 are used to select the Memory
-Base address of the RAM (2K) and the PROM.
-
- Switch | Hex RAM | Hex ROM
- 7 8 9 10 | Address | Address
- ----------------|---------|-----------
- OFF OFF ON ON | C0000 | C8000
- OFF OFF ON OFF | D0000 | D8000 (Default)
- OFF OFF OFF ON | E0000 | E8000
-
-Note: Other MEM-Base addresses seem to be selectable, but only the above
- combinations are documented.
-
-
-Setting the Interrupt Line
---------------------------
-
-To select a hardware interrupt level install one (only one!) of the jumpers
-JP3 through JP13 using the following table:
-
- Jumper | IRQ
- -------|-----------------
- 3 | 14
- 4 | 15
- 5 | 12
- 6 | 11
- 7 | 10
- 8 | 3
- 9 | 4
- 10 | 5
- 11 | 6
- 12 | 7
- 13 | 2 (=9) Default!
-
-Note: - Do not use JP11=IRQ6, it may conflict with your Floppy Disk
- Controller
- - Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
- Hard Disk, it may conflict with their controllers
-
-
-Setting the Timeout Parameters
-------------------------------
-
-The jumpers labeled JP1 and JP2 are used to determine the timeout
-parameters. These two jumpers are normally left open.

-to the network must have an unique node ID which must not be 0.
-Switch 1 (ID0) serves as the least significant bit (LSB).
-
-Setting one of the switches to OFF means "1", ON means "0".
-
-The node ID is the sum of the values of all switches set to "1"
-These values are:

- 5 | 16
- 6 | 32
- 7 | 64
- 8 | 128
-
-Don't set this to 0 or 255; these values are reserved.
-
-
-Setting the I/O Base Address
-----------------------------
-
-The switches 1 to 6 of switch block SW1 are used to select one
-of 32 possible I/O Base addresses using the following tables
-
- | Hex
- Switch | Value
- -------|-------
- 1 | 200
- 2 | 100
- 3 | 80
- 4 | 40
- 5 | 20
- 6 | 10
-
-The I/O address is sum of all switches set to "1". Remember that
-the I/O address space bellow 0x200 is RESERVED for mainboard, so
-switch 1 should be ALWAYS SET TO OFF.
-
-
-Setting the Base Memory (RAM) buffer Address
---------------------------------------------
-
-The memory buffer (RAM) requires 2K. The base of this buffer can be
-located in any of sixteen positions. However, the addresses below
-A0000 are likely to cause system hang because there's main RAM.
-
-Jumpers 7-10 of switch block SW1 select the Memory Base address.
-
- Switch | Hex RAM
- 7 8 9 10 | Address
- ----------------|---------
- OFF OFF OFF OFF | F0000 (conflicts with main BIOS)
- OFF OFF OFF ON | E0000
- OFF OFF ON OFF | D0000
- OFF OFF ON ON | C0000 (conflicts with video BIOS)
- OFF ON OFF OFF | B0000 (conflicts with mono video)
- OFF ON OFF ON | A0000 (conflicts with graphics)
-
-
-Setting the Interrupt Line
---------------------------
-
-Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
-shorted, OFF means open.
-
- Jumper | IRQ
- 1 2 3 4 5 |
- ----------------------------
- ON OFF OFF OFF OFF | 7
- OFF ON OFF OFF OFF | 5
- OFF OFF ON OFF OFF | 4
- OFF OFF OFF ON OFF | 3
- OFF OFF OFF OFF ON | 2
-
-
-Unknown jumpers & sockets
--------------------------
-
-I know nothing about these. I just guess that J16&J17 are timeout
-jumpers and maybe one of J18-J21 selects ROM. Also J6-J10 and
-J11-J15 are connecting IRQ2-7 to some pins on the UFSs. I can't
-guess the purpose.

-Setting the Node ID
--------------------
-
-The eight switches in SW2 are used to set the node ID. Each node attached to
-the network must have an unique node ID which must not be 0. Switch 1 (ID0)
-serves as the least significant bit (LSB).
-
-Setting one of the switches to Off means "1", On means "0".
-
-The node ID is the sum of the values of all switches set to "1"
-These values are:
-
- Switch | Label | Value
- -------|-------|-------
- 1 | ID0 | 1
- 2 | ID1 | 2
- 3 | ID2 | 4
- 4 | ID3 | 8
- 5 | ID4 | 16
- 6 | ID5 | 32
- 7 | ID6 | 64
- 8 | ID7 | 128
-
-Setting the I/O Base Address
-----------------------------
-
-The last three switches in switch block SW1 are used to select one
-of eight possible I/O Base addresses using the following table:
-
-
- Switch | Hex I/O
- 6 7 8 | Address
- ------------|--------
- ON ON ON | 260 (Manufacturer's default)
- OFF ON ON | 290
- ON OFF ON | 2E0
- OFF OFF ON | 2F0
- ON ON OFF | 300
- OFF ON OFF | 350
- ON OFF OFF | 380
- OFF OFF OFF | 3E0
-
-
-Setting the Base Memory (RAM) buffer Address
---------------------------------------------
-
-The memory buffer (RAM) requires 2K. The base of this buffer can be
-located in any of eight positions. The address of the Boot Prom is
-memory base + 0x2000.
-Jumpers 3-5 of switch block SW1 select the Memory Base address.
-
- Switch | Hex RAM | Hex ROM
- 1 2 3 4 5 | Address | Address *)
- --------------------|---------|-----------
- ON ON ON ON ON | C0000 | C2000
- ON ON OFF ON ON | C4000 | C6000 (Manufacturer's default)
- ON ON ON OFF ON | CC000 | CE000
- ON ON OFF OFF ON | D0000 | D2000
- ON ON ON ON OFF | D4000 | D6000
- ON ON OFF ON OFF | D8000 | DA000
- ON ON ON OFF OFF | DC000 | DE000
- ON ON OFF OFF OFF | E0000 | E2000
-
-*) To enable the Boot ROM short the jumper J2.
-
-The jumpers 1 and 2 probably add 0x0800 and 0x1000 to RAM address.
-
-
-Setting the Interrupt Line
---------------------------
-
-Jumpers 1-5 of the jumper block J1 control the IRQ level. ON means
-shorted, OFF means open.
-
- Jumper | IRQ
- 1 2 3 4 5 |
- ----------------------------
- ON OFF OFF OFF OFF | 2
- OFF ON OFF OFF OFF | 3
- OFF OFF ON OFF OFF | 4
- OFF OFF OFF ON OFF | 5
- OFF OFF OFF OFF ON | 7
-
-
-Setting the Timeout Parameters
-------------------------------
-
-The jumpers J3 are used to set the timeout parameters. These two
-jumpers are normally left open.

-There is a DIP-switch with 8 switches, used to set the shared memory address
-to be used. The first 6 switches set the address, the 7th doesn't have any
-function, and the 8th switch is used to select "compatible" or "enhanced".
-When I got my two cards, one of them had this switch set to "enhanced". That
-card didn't work at all, it wasn't even recognized by the driver. The other
-card had this switch set to "compatible" and it behaved absolutely normally. I
-guess that the switch on one of the cards, must have been changed accidentally
-when the card was taken out of its former host. The question remains
-unanswered, what is the purpose of the "enhanced" position?
-
-[Avery's note: "enhanced" probably either disables shared memory (use IO
-ports instead) or disables IO ports (use memory addresses instead). This
-varies by the type of card involved. I fail to see how either of these
-enhance anything. Send me more detailed information about this mode, or
-just use "compatible" mode instead.]

-
-[Avery's note: these don't work with my driver for some reason. These cards
-SEEM to have settings similar to the PDI508Plus, which is
-software-configured and doesn't work with my driver either. The "Waterloo
-chip" is a boot PROM, probably designed specifically for the University of
-Waterloo. If you have any further information about this card, please
-e-mail me.]
-
-The probe has not been able to detect the card on any of the J2 settings,
-and I tried them again with the "Waterloo" chip removed.

-NONAME 16-BIT ARCNET
-====================
-
-The manual of my 8-Bit NONAME ARCnet Card contains another description
-of a 16-Bit Coax / Twisted Pair Card. This description is incomplete,
-because there are missing two pages in the manual booklet. (The table
-of contents reports pages ... 2-9, 2-11, 2-12, 3-1, ... but inside
-the booklet there is a different way of counting ... 2-9, 2-10, A-1,
-(empty page), 3-1, ..., 3-18, A-1 (again), A-2)
-Also the picture of the board layout is not as good as the picture of
-8-Bit card, because there isn't any letter like "SW1" written to the
-picture.
-Should somebody have such a board, please feel free to complete this
-description or to send a mail to me!

-8-bit cards ("Made in Taiwan R.O.C.")
------------
- - from Vojtech Pavlik <vojtech@suse.cz>
-
-I have named this ARCnet card "NONAME", since I got only the card with
-no manual at all and the only text identifying the manufacturer is
-"MADE IN TAIWAN R.O.C" printed on the card.

- 6-8: Base I/O Address Select
-SW2 1-8: Node ID Select (ID0-ID7)
-SW3 1-5: IRQ Select
- 6-7: Extra Timeout
- 8 : ROM Enable
-JP1 Led connector
-BNC Coax connector
-
-Although the jumpers SW1 and SW3 are marked SW, not JP, they are jumpers, not
-switches.
-
-Setting the jumpers to ON means connecting the upper two pins, off the bottom
-two - or - in case of IRQ setting, connecting none of them at all.
-
-Setting the Node ID
--------------------
-
-The eight switches in SW2 are used to set the node ID. Each node attached
-to the network must have an unique node ID which must not be 0.
-Switch 1 (ID0) serves as the least significant bit (LSB).
-
-Setting one of the switches to Off means "1", On means "0".
-
-The node ID is the sum of the values of all switches set to "1"
-These values are:
-
- Switch | Label | Value
- -------|-------|-------
- 1 | ID0 | 1
- 2 | ID1 | 2
- 3 | ID2 | 4
- 4 | ID3 | 8
- 5 | ID4 | 16
- 6 | ID5 | 32
- 7 | ID6 | 64
- 8 | ID7 | 128

-Some Examples:
-
- Switch | Hex | Decimal
- 8 7 6 5 4 3 2 1 | Node ID | Node ID

- 1 1 1 1 1 1 1 1 | FF | 255
-
-
-Setting the I/O Base Address
-----------------------------
-
-The last three switches in switch block SW1 are used to select one
-of eight possible I/O Base addresses using the following table
-
-
- Switch | Hex I/O
- 6 7 8 | Address
- ------------|--------
- ON ON ON | 260
- OFF ON ON | 290
- ON OFF ON | 2E0 (Manufacturer's default)
- OFF OFF ON | 2F0
- ON ON OFF | 300
- OFF ON OFF | 350
- ON OFF OFF | 380
- OFF OFF OFF | 3E0
-
-
-Setting the Base Memory (RAM) buffer Address
---------------------------------------------
-
-The memory buffer (RAM) requires 2K. The base of this buffer can be
-located in any of eight positions. The address of the Boot Prom is
-memory base + 0x2000.
-Jumpers 3-5 of jumper block SW1 select the Memory Base address.
-
- Switch | Hex RAM | Hex ROM
- 1 2 3 4 5 | Address | Address *)
- --------------------|---------|-----------
- ON ON ON ON ON | C0000 | C2000
- ON ON OFF ON ON | C4000 | C6000
- ON ON ON OFF ON | CC000 | CE000
- ON ON OFF OFF ON | D0000 | D2000 (Manufacturer's default)
- ON ON ON ON OFF | D4000 | D6000
- ON ON OFF ON OFF | D8000 | DA000
- ON ON ON OFF OFF | DC000 | DE000
- ON ON OFF OFF OFF | E0000 | E2000
-
-*) To enable the Boot ROM set the jumper 8 of jumper block SW3 to position ON.
-
-The jumpers 1 and 2 probably add 0x0800, 0x1000 and 0x1800 to RAM adders.
-
-Setting the Interrupt Line
---------------------------
-
-Jumpers 1-5 of the jumper block SW3 control the IRQ level.
-
- Jumper | IRQ
- 1 2 3 4 5 |
- ----------------------------
- ON OFF OFF OFF OFF | 2
- OFF ON OFF OFF OFF | 3
- OFF OFF ON OFF OFF | 4
- OFF OFF OFF ON OFF | 5
- OFF OFF OFF OFF ON | 7
-
-
-Setting the Timeout Parameters
-------------------------------
-
-The jumpers 6-7 of the jumper block SW3 are used to determine the timeout
-parameters. These two jumpers are normally left in the OFF position.

-
-SW1: Timeouts, Interrupt and ROM
----------------------------------
-
-To select a hardware interrupt level set one (only one!) of the dip switches
-up (on) SW1...(switches 1-5)
-IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
-
-The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
-are used to determine the timeout parameters. These two dip switches
-are normally left off (down).
-
- To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM.
- The default is jumper ROM not installed.
-
-
-Setting the I/O Base Address
-----------------------------
-
-The last three switches in switch group SW2 are used to select one
-of eight possible I/O Base addresses using the following table
-
-
- Switch | Hex I/O
- 4 5 6 | Address
- -------|--------
- 0 0 0 | 260
- 0 0 1 | 290
- 0 1 0 | 2E0 (Manufacturer's default)

- 1 0 0 | 300
- 1 0 1 | 350
- 1 1 0 | 380
- 1 1 1 | 3E0
-
-
-Setting the Base Memory Address (RAM & ROM)
--------------------------------------------
-
-The memory buffer requires 2K of a 16K block of RAM. The base of this
-16K block can be located in any of eight positions.
-Switches 1-3 of switch group SW2 select the Base of the 16K block.
-(0 = DOWN, 1 = UP)
-I could, however, only verify two settings...
-
- Switch| Hex RAM | Hex ROM
- 1 2 3 | Address | Address
- ------|---------|-----------
- 0 0 0 | E0000 | E2000
- 0 0 1 | D0000 | D2000 (Manufacturer's default)

- 0 1 1 | ????? | ?????
- 1 0 0 | ????? | ?????
- 1 0 1 | ????? | ?????
- 1 1 0 | ????? | ?????
- 1 1 1 | ????? | ?????
-
-
-Setting the Node ID
--------------------
-
-The eight switches in group SW3 are used to set the node ID.
-Each node attached to the network must have an unique node ID which
-must be different from 0.
-Switch 1 serves as the least significant bit (LSB).
-switches in the DOWN position are OFF (0) and in the UP position are ON (1)
-
-The node ID is the sum of the values of all switches set to "1"
-These values are:
- Switch | Value
- -------|-------
- 1 | 1
- 2 | 2
- 3 | 4
- 4 | 8
- 5 | 16
- 6 | 32
