INT 16 - Compaq 386 - SET CPU SPEED
AH = F0h
AL = speed
00h equivalent to 6 MHz 80286 (COMMON)
01h equivalent to 8 MHz 80286 (FAST)
02h full 16 MHz (HIGH)
03h toggles between 8 MHz-equivalent and speed set by system board
switch (AUTO or HIGH)
08h full 16 MHz except 8 MHz-equivalent during floppy disk access
09h specify speed directly
CX = speed value, 1 (slowest) to 50 (full), 3 ~= 8088
