<p><b>Return:</b><br>CF clear if successful (after system leaves idle state)
CF set on error
AH = error code (03h,0Bh) <a href="rb-1394.htm#Table473" tppabs="http://www.ctyme.com/intr/rb-1394.htm#Table473">(see #00473)</a>
</PRE>
<p><b>Notes:</b>
Call when the system is idle and should be suspended until the next
system event or interrupt.
Should not be called from within a hardware interrupt handler to avoid
reentrance problems.
If an interrupt causes the system to resume normal processing, the
interrupt may or may not have been handled when the BIOS returns
from this call; thus, the caller should allow interrupts on return.
Interrupt handlers may not retain control if the BIOS allows
interrupts while in idle mode even if they are able to determine
that they were called from idle mode.
The caller should issue this call continuously in a loop until it needs
to perform some processing of its own
