AX = 5305h
Return:
CF clear if successful (after system leaves idle state) CF set on error AH = error code (03h,0Bh) (see #00473)
Notes: 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
