Hmm. Sounds possible. Is there anything wrong with the tripple fault
path. Which it sounds like this stuff triggers?
But if this code does get to FFFF:0000 that is physical address:
0xFFFF0 which is where we get to initially.
I guess the real question is what do we want of a reboot path?
I've been doing some research trying to get a good idea, of what
will make decent default BIOS behavior and this is an important
question. I'll try to write up a tenative proposal this week.
