I've got Boot! ... But ...
Using the ASUS P2B only on a warm boot, and I deselected some Run non-VGA option Roms:
[*] Run VGA option ROMs [ ] Run non-VGA option ROMs
I'm attaching the warmboot log, and then a cold boot log (again, the cold boot fails at raminit). (I'm also attaching .config for kicks for anybody browsing the lists.)
When I'm booted, I get a constant reboot after loading SeaBIOS. Pressing F12 quickly doesn't show any boot options. Likely because I've disabled the "Run non-VGA option ROMs"?
Think I'll take a break for the night and read a few of the "Intel® 64 and IA-32 Architectures Software Developer's Manuals" hosted at: http://www.intel.com/products/processor/manuals/
(From what Keith just wrote just prior to this email, I need to read some raminit code comments and get some memory stick config dumps.)
