Hmm..I've been running a hacked version of the ida driver on -3.0
current, and now on -4.0 current (for the past couple of months). So,
while, the EISA/wd stuff in 3.0 may have changed, it hasn't changed a
lot. All I've changed in ida.c is hard-coding the port (to 0x6000 in
my case). I'll send you my version of ida.c seperately.
also, can you post the dmseg lines from 2.2.7 and 3.0?
Here's how I would recommend you do it:
1. Install 2.2.x using one of the boot floppies from Mark's site.
2. cvsup to 3.0-stable
3. Modify the upgrade kernel config file to include the ida
drivers. Modify the kernel sources according to the instructions on
Mark's site. Modify ida.c so that it always goes to port 0x1000
(Look at where I did it in my version of ida.c )
4. run the upgrade procedure (I ran make aout-to-elf-build. I don't know
whether it is still the same)
5. DO not install the new boot blocks (just in case the kernel fails)
6. try out the new kernel. If it fails, default to the old 2.2.x
kernel, and make modifications to ida.c. Keep at it till it works.
(don't take this as gospel. Read the upgrade makefiles to see what
exactly it is doing)
OR
I can build you a kernel with the port hardcoded to 0x1000. I would
rather not do this since the only means I have of transferring the
kernel from my home machine to work is a 28.8 modem.
[I realize that all this is a big hack, and that Mark and a bunch of
others are cringing, but *shrug* practicality first]
