AX = FF01h DX = number of clock ticks to delay
Return:
AH = status 00h successful 01h SND busy
Notes: If successful, execution returns to the caller after the delay expires; if SND is busy, execution returns immediately. The IC v2.0 implementation of this API makes no special allowance for time rollover at midnight, which can cause the delay to be over one hour if this function is called just before the BIOS time count rolls over and the delay extends into the next day
