David,
PC based machines have lpt ports (typically) at 0x378h -lpt1 (irq 7),
0x278h -lpt2 (irq 5), 0x3bc - lpt3 (irq 7. Yes the two ports by
default have an irq conflict).
I know at least on an ms-dos machine you can use debug to read the address
at 0:408 which will give you the port addresses in little endian (i
think it's little endian). A port address of 0x378 would be read as
78 03 00 00 00 00. The next few numbers that I replaced with 00 are
space for additional parallel ports. If you had all three ports
installed you'd see 78 03 78 02 bc 03.

Subject: [PARPORT] Parameters (newbie question)
Ok. I've compiled all the modules, added the PARIDE elements to /devs, and
now I need to know how to determine the parameters to pass when I insert
the
modules under kernel 2.0.30.
Step 1. insmod paride
Step 2. insmod pcd
Step 3. insmod pcd0<????,????>
It's step 3 that I'm having trouble with. The home page for parport and the
README in the paride archive are kinda cryptic. Is there a standard hex
address for lpt1: on DOS machines, or is there some probe I can run to find
it? RedHat install found my Backpack CD-ROM with no problem, so I know it's
possible somehow. :)
