this is the south bridge. This is the "function" (sub-device) of the southbridge that controls flash write.
reg 0x45 has a value of: 0x60, binary 0110 0000 to make eeprom flashable, bits 5,2 must == 01. see page 76 of the book.
bit 5 is 1 and bit 2 is 0, which I think is 10. We need to flip them.
0100 0100
4 4
Try this setpci -s 0:1.0 45.b (read the value) setpci -s 0:1.0 45.b=44 setpci -s 0:1.0 45.b (read the value back and make sure it is 44)
then run flash_rom and see what happens.
EEPROM Found! nice! So now I'll try getting good old linuxbios on there...
Seriously thanks alot...
Is there anything I need to do to flash_rom.c to get that to work all the time?
having someone explain what the -xxx output is sure helps understand what it is (besides knowing it is a hex dump)...
well, now that we know what works, I want to patch flash_rom and have you test it.

I just fixed flash_rom and committed. If you could reset your board (to reset the southbridge) and try just running flash_rom (NO manual setpci commands) let me know if this worked.

Sorry no it didn't though the output from your new function prints out OK... the ids 1 & 2 = 0xff

never fails. Can you run flash_rom and send me this:
lspci -s 0:1.0 -xxx
thanks
