I see :) So that's what I did wrong. How many of these values are actually used by linuxbios? For instance, I had baud_rate set to 1200 and dual_core was off; yet the system booted just fine with 115200 baud on serial, and I could see both cores on this dual-core cpu board.
The checksum was wrong, so none of the values were used.
It's not you doing this wrong. I think linuxbios should in fact reset the extended linuxbios range in cmos to the values it has hardcoded as defaults from the cmos options file.
I can't really seem to find any documentation about all the settings that are possible with lxbios; most seem straightforward enough, but is there something out there that describes each field?
No. The wild thing is these settings may be different in each mainboard and many of them are there because of copy & paste.
boot_first = HDD boot_second = Network boot_third = Floppy boot_index = 0xe boot_countdown = 0xfa
I think these are used by some payload. Baremetal toolkit? Etherboot?
