From: Guy Sotomayor
the LOADALL instructions including all of it's
warts (and its inability
to switch back from protected mode)
Good to have that confirmed (for the 286; apparently it works in the 386).
the other way to get back to real mode from protected
mode is via a
triple-fault.
Any insight into why IBM didn't use that, but went with the (allegedly slow)
keyboard hack?
