-This document describes the ACT2000 driver for the
-IBM Active 2000 ISDN card.
-There are 3 Types of this card available. A ISA-, MCA-, and PCMCIA-Bus
-Version. Currently, only the ISA-Bus version of the card is supported.
-However MCA and PCMCIA will follow soon.
-The ISA-Bus Version uses 8 IO-ports. The base port address has to be set
-manually using the DIP switches.
-Setting up the DIP switches for the IBM Active 2000 ISDN card:
- Note: S5 and S6 always set off!
- S1 S2 S3 S4 Base-port
- on on on on 0x0200 (Factory default)
- off on on on 0x0240
- on off on on 0x0280
- off off on on 0x02c0
- on on off on 0x0300
- off on off on 0x0340
- on off off on 0x0380
- on on on off 0xcfe0
- off on on off 0xcfa0
- on off on off 0xcf60
- off off on off 0xcf20
- on on off off 0xcee0
- off on off off 0xcea0
- on off off off 0xce60
- off off off off Card disabled
-IRQ is configured by software. Possible values are:
- 3, 5, 7, 10, 11, 12, 15 and none (polled mode)
-The ACT2000 driver may either be built into the kernel or as a module.
-Initialization depends on how the driver is built:
-Driver built into the kernel:
- The ACT2000 driver can be configured using the commandline-feature while
- loading the kernel with LILO or LOADLIN. It accepts the following syntax:
- act2000=b,p,i[,idstring]
- where
- b = Bus-Type (1=ISA, 2=MCA, 3=PCMCIA)
- p = portbase (-1 means autoprobe)
- i = Interrupt (-1 means use next free IRQ, 0 means polled mode)
- The idstring is an arbitrary string used for referencing the card
- by the actctrl tool later.
- Defaults used, when no parameters given at all:
- 1,-1,-1,""
- which means: Autoprobe for an ISA card, use next free IRQ, let the
- ISDN linklevel fill the IdString (usually "line0" for the first card).
- If you like to use more than one card, you can use the program
- "actctrl" from the utility-package to configure additional cards.
- Using the "actctrl"-utility, portbase and irq can also be changed
- during runtime. The D-channel protocol is configured by the "dproto"
- option of the "actctrl"-utility after loading the firmware into the
- card's memory using the "actctrl"-utility.
-Driver built as module:
- The module act2000.o can be configured during modprobe (insmod) by
- appending its parameters to the modprobe resp. insmod commandline.
- The following syntax is accepted:
- act_bus=b act_port=p act_irq=i act_id=idstring
- where b, p, i and idstring have the same meanings as the parameters
- described for the builtin version above.
- Using the "actctrl"-utility, the same features apply to the modularized
- version as to the kernel-builtin one. (i.e. loading of firmware and
- configuring the D-channel protocol)
-Loading the firmware into the card:
- The firmware is supplied together with the isdn4k-utils package. It
- can be found in the subdirectory act2000/firmware/
- Assuming you have installed the utility-package correctly, the firmware
- will be downloaded into the card using the following command:
- actctrl -d idstring load /etc/isdn/bip11.btl
- where idstring is the Name of the card, given during insmod-time or
- (for kernel-builtin driver) on the kernel commandline. If only one
- ISDN card is used, the -d isdstrin may be omitted.
- For further documentation (adding more IBM Active 2000 cards), refer to
- the manpage actctrl.8 which is included in the isdn4k-utils package.
