Interesting. This implies that the failure is very early in stage 2, or
during the transition from stage 1 (setup) to stage 2 (decompression.)
This is also the point at which transition happens from 16-bit real mode
to 32-bit protected mode.
This could imply either that something is going on clobbering high
memory, or the protected mode transition failed. Either is a Very Bad
Thing.
Are you using the syslinux menu system at all? If so, does it work on
this machine?
