2decd76771 Be much more carefull about what we leave in unused registers when we call 
the APM-bios.
This stabilizes a couple of APM bioses quite a bit.
They all make the mistake of going into 16-bit mode, without clearing the
top half of the 32bit registers.
Later they do a
|	movw %si,$0x7331
|	movw %ax,0x6(%si)
or something along those lines and crash and burn, because their segment
is already relocated, so adding 0xf0171ce9 to the base of it is bad news.

At least SystemSoft is guilty of this bummer.

4a5014e48b Got rid of "APM" macro. Now only NAPM is needed to activate the APM stuff. 1994-10-10 01:14:03 +00:00

1ed171d405 Ripped out a lot of stuff made to circumvent the previous bogus assy stuff. 
Ripped out the "hooks".  Until we know how we want to do it, we shouldn't
start hacking anyway.  Still panics my machine though.

3d1dcf1ba5 Replaced the magic register union with inline assembler. Now it works 
"mostly".  My machine still panics from time to time, and I think the
problem is a stack-problem.

64bb0d8861 On my GW2K Handbook486 this code would reset when called from locore.s 
I think I have narrowed this down to the stack being overflown.  I have
taken the push/pop of %fs out, it shouldn't be needed anyway, but the
real & correct solution might to save the registers on the stack in
locore.s before calling this stuff.
