INT 1A - SND - PAUSE 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(Application Program[ming] Interface) The defined set of calls which a program may make to interact with or request services of the operating system or environment under which it is running. Because the inputs and outputs of the calls are well-defined, a program using the API can continue using the identical calls even if the internal organization of the program providing the API changes. 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(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware. The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. time count rolls over and the delay extends into the next day SeeAlso: AX=FF00h,INT 15/AH=86h,INT 62/AX=0096h,INT 7F/AH=E8h,INT 80/BX=0009h SeeAlso: INT E0/CL=BDh
