dmesg reports 'tulip.c:v0.91g-ppc 7/16/99 email@example.com' . I
should mention I'm running a Mandrake 6.1distribution with a clean 2.2.14
source tree installed. I'm not at the machine right now, does this version
(0.91g) have the option of using memory space instead of I/O space??? I
think I should try and grap the tulip.c:v0.92 4/17/2000 version. I see 0.92
by default does not use 'USE_IO_OPS' which is what we want, I believe.
I ran pci-config once with ' -a ' and got this. Really I haven't played
with it that much. I need to look at the code to
understand how to use it correctly.

I don't think the EEPROM is the problem.

Hmmm, these are not likely correct.

That's definitely bogus. The chip doesn't exist in I/O space.
Run pci-config, or something similar, to see if the chip is in ACPI power
down mode. But this isn't likely -- some program would have to put the

This is just the result of the 21143 chip not existing in I/O space.
