[tulip] tulip-diag eeprom writing - some questions

Hi Donald,

dmesg reports 'tulip.c:v0.91g-ppc 7/16/99 becker@cesdis.gsfc.nasa.gov' . 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
chip
to sleep.

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