-This is the ALPHA version of the ltpc driver.
-
-In order to use it, you will need at least version 1.3.3 of the
-netatalk package, and the Apple or Farallon LocalTalk PC card.
-There are a number of different LocalTalk cards for the PC; this
-driver applies only to the one with the 65c02 processor chip on it.
-
-To include it in the kernel, select the CONFIG_LTPC switch in the
-configuration dialog. You can also compile it as a module.
-
-While the driver will attempt to autoprobe the I/O port address, IRQ
-line, and DMA channel of the card, this does not always work. For
-this reason, you should be prepared to supply these parameters
-yourself. (see "Card Configuration" below for how to determine or
-change the settings on your card)
-
-When the driver is compiled into the kernel, you can add a line such
-as the following to your /etc/lilo.conf:
-
- append="ltpc=0x240,9,1"
-
-where the parameters (in order) are the port address, IRQ, and DMA
-channel. The second and third values can be omitted, in which case
-the driver will try to determine them itself.
-
-If you load the driver as a module, you can pass the parameters "io=",
-"irq=", and "dma=" on the command line with insmod or modprobe, or add
-them as options in a configuration file in /etc/modprobe.d/ directory:
-
- alias lt0 ltpc # autoload the module when the interface is configured
- options ltpc io=0x240 irq=9 dma=1
-
-Before starting up the netatalk demons (perhaps in rc.local), you
-need to add a line such as:
-
- /sbin/ifconfig lt0 127.0.0.42
-
-The address is unimportant - however, the card needs to be configured
-with ifconfig so that Netatalk can find it.
-
-The appropriate netatalk configuration depends on whether you are
-attached to a network that includes AppleTalk routers or not. If,
-like me, you are simply connecting to your home Macintoshes and
-printers, you need to set up netatalk to "seed". The way I do this
-is to have the lines
-
- dummy -seed -phase 2 -net 2000 -addr 2000.26 -zone "1033"
- lt0 -seed -phase 1 -net 1033 -addr 1033.27 -zone "1033"
-
-in my atalkd.conf. What is going on here is that I need to fool
-netatalk into thinking that there are two AppleTalk interfaces
-present; otherwise, it refuses to seed. This is a hack, and a more
-permanent solution would be to alter the netatalk code. Also, make
-sure you have the correct name for the dummy interface - If it's
-compiled as a module, you will need to refer to it as "dummy0" or some
-such.
-
-If you are attached to an extended AppleTalk network, with routers on
-it, then you don't need to fool around with this -- the appropriate
-line in atalkd.conf is
-
- lt0 -phase 1
-
---------------------------------------
-
-Card Configuration:
-
-The interrupts and so forth are configured via the dipswitch on the
-board. Set the switches so as not to conflict with other hardware.
-
- Interrupts -- set at most one. If none are set, the driver uses
- polled mode. Because the card was developed in the XT era, the
- original documentation refers to IRQ2. Since you'll be running
- this on an AT (or later) class machine, that really means IRQ9.
-
- SW1 IRQ 4
- SW2 IRQ 3
- SW3 IRQ 9 (2 in original card documentation only applies to XT)
-
-
- DMA -- choose DMA 1 or 3, and set both corresponding switches.
-
- SW4 DMA 3
- SW5 DMA 1
- SW6 DMA 3
- SW7 DMA 1
-
-
- I/O address -- choose one.
-
- SW8 220 / 240
-
---------------------------------------
-
-IP:
-
-Yes, it is possible to do IP over LocalTalk. However, you can't just
-treat the LocalTalk device like an ordinary Ethernet device, even if
-that's what it looks like to Netatalk.
-
-Instead, you follow the same procedure as for doing IP in EtherTalk.
-See Documentation/networking/ipddp.txt for more information about the
-kernel driver and userspace tools needed.
-
---------------------------------------
-
-BUGS:
-
-IRQ autoprobing often doesn't work on a cold boot. To get around
-this, either compile the driver as a module, or pass the parameters
-for the card to the kernel as described above.
-
-Also, as usual, autoprobing is not recommended when you use the driver
-as a module. (though it usually works at boot time, at least)
-
-Polled mode is *really* slow sometimes, but this seems to depend on
-the configuration of the network.
-
-It may theoretically be possible to use two LTPC cards in the same
-machine, but this is unsupported, so if you really want to do this,
-you'll probably have to hack the initialization code a bit.

- Thanks to Alan Cox for helpful discussions early on in this
