Advanced Power Management v1.0+ - CPU BUSY

AX = 5306h

Return:
CF clear if successful CF set on error AH = error code (03h,0Bh) (see #00473)

Notes: Called to ensure that the system runs at full speed even on systems where the BIOS is unable to recognize increased activity (especially if interrupts are hooked by other programs and not chained to the BIOS). This call may be made even when the system is already running at full speed, but it will create unnecessary overhead. Should not be called from within a hardware interrupt handler to avoid reentrance problems
