<p><b>Notes:</b>
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
