Description
I noticed that if I flash Coreboot, and wipe the CMOS out completely (remove the battery and power for a bit), sometimes my system won't POST. Might work the first time, might take a reset or two, and worst-case it took 5 resets in a row for it to POST.
If I boot the ASUS vendor BIOS, remove the BIOS chip, and replace it with a Coreboot chip, it seemingly POSTs fine consistently.
For Coreboot, I'm using the CMOS for NVRAM, and also the option that loads defaults every boot.
No data to display
