I did back them up, but..
I backed up my old bios, and tried to flash the new ones.
It said it timed out waiting for the eeprom to clear, and quit.
I tried again, same error.
I rebooted, no post. I put in my pci card, nvflash reports no nvidia cards on the system... is there any way I can override it and force it to install ... a bios? Right now I think it's blank... or just seriously Mucked up.
