Hi,
Thanks for the pointer, Warner. I looked at the OpenBSD code and didn't
really see anything special where the EEPROM romwidth stuff is used
(except in (b) below).
I then made the following hacks to if_dc.c:
a) Create a new device ID
b) Changed the dc_eeprom_putbyte() to feed the bits properly (I think
there's a bug in the original code)
c) Changed dc_delay() to a fixed DELAY(20)
This yields the following when I plug in the Linksys PCM200 card:
pccbb0: card inserted: event=0x00000000, state=30000b20
pccbb0: pccbb_power: CARD_VCC_0V and CARD_VPP_0V [44]
pccbb0: pccbb_power: CARD_VCC_3V and CARD_VPP_VCC [11]
pccbb0: bad Vcc request. ctrl=0x33, status=0x30000b20
pccbb_power: CARD_VCC_3V and CARD_VPP_VCC [11]

Success, it seems, as the MAC address is now the right one.
However, when I ifconfig up the device, I will just a whole stream of
dc0: device timeouts.
Is it due to my dumb laptop Bios having not properly assigned the IRQ's
for the cardbus stuff? The "intpin=a, irq=128" line above looks
unhealthy. If this is indeed the case, any idea if I can whack the Bios
into submission? Or some other way I can get the IRQ's through?
Thanks for any additional pointers!
Regards
