Log:
When enabling A20 put upper limit on amount of time we wait for the
keyboard controller to get ready (65K x ISA access time, visually
around 1
second). If we have wait more than that amount it's likely that the
hardware is a legacy-free one and simply doesn't have keyboard
controller
and doesn't require enabling A20 at all.
This makes cdboot working for MacBook Pro with Boot Camp.
You'll probably need to do the same for boot1 and I think BTX.
Alternatively, you should see how the loader is handling A20 and
do that in the various boot programs instead (I think there's a PR
somewhere about using a BIOS call instead of frobbing the keyboard
controller directly that supposedly fixes things like USB keyboards
in the loader.)
Do you think this might also be the problem that prevents FreeBSD
from booting on Virtual PC for Mac OS/PPC? That's been frustrating
me for months, but I haven't had time to do anything about it.
