I am trying to understand the Opteron Address Map, and

everything but the PCI I/O section, but I have few

a good document to help one setup the address map,

If you have you Flash mapped to 0x - 0x3 then you can't use your

why on earth would you map flash to this address? it makes no sense to me

flash is at the usual 0xfffc, memory at 0x I assume.

Hello,
At what address should the linuxbios.rom and the kernel image file should be kept in Flash memory? My linuxbios.rom is 256KB and kernel image is 1.1MB.

Ron, please apply this patch.
It should not break anything, and significantly speeds up booting of
certain boards like EPIA.
This patch does two things:
- Add write-through cache for 0xf-0xf before uncompressing
linuxbios_c, if option XIP_LOW is defined.
- Changes existing XIP (execute
motherboard's MAC address.
Thanks to the author of write_cmos.c, we were able to repair the damage
(as least temporarily), but needed to make a few little small changes to
write_cmos.c so that we didn't have to re-compile it each time to change
the MAC address, and also, the PCI address of the ISA

There's no record of the value of the MAC address anywhere, so it can't

This is probably because the MAC address in flash is 0 too. Consider a

I am pretty sure you won't find an eeprom.
Greetings,
AFAIK, on the 630e, the MAC address is actually stored in CMOS at index
9-14. I'm not sure how that came to be zeroed, but if you put it back
there, all will be well. The regular BIOS sets that during POST.
