Hi,

It seems recently one of my two onboard NICs has decided to not
remember its MAC address between reboots. Since I just updated the
BIOS firmware, I suspect that as the culprit but I also upgraded to
Fedora 8 about the same time so it may be to blame. I don't know.
When you update the bios, the tool accept a parameter for the mac
address.. Each time you flash the bios, you need to give the mac
address for the integrated ethernet (usually written on the top of the
mainboard ), so it can be hardcoded into the bios...

I've updated my share of BIOS... Large share.
Never seen a BIOS upgrade that erases the MAC address.

Most likely the on-board NIC has been fried.

typically the MAC address is programmed into an on-board eeprom connected to the NIC. That's probably what's fried (or simply erased).
