INT 15 - IBMInternational Busiuness MachinesInternational Busiuness Machines) A hardware, software and other service technology company founded in 1911. SurePath 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. - WAIT REQUESTED TIME PERIOD
	AH = 08h
	AL = function
	    00h wait in increments of 15.025 microseconds
		CX = number of time increments to wait (0000h = maximum)
	    80h wait in increments of 840 ns
		ECX = number of time increments to wait
	    81h I/O event wait
		BH = bitmask of bits to check
		BL = expected pattern
		DX = I/O port address
		ECX = number of 840 ns microticks to wait
		Return: ECX = 00000000h if expected pattern did not occur
	    82h memory event wait
		BH = bitmask of bits to check
		BL = expected pattern
		ES:SI -> BYTE to check
		ECX = number of 840 ns microticks to wait
		Return: ECX = 00000000h if expected pattern did not occur
	    other reserved
Return: CF clear if successful
	CF set on error
	AH = status
	    00h successful
	    01h used 15.025 microsecond interval, time rounded up

	    86h function not supported
Notes:	IBMInternational Busiuness MachinesInternational Busiuness Machines) A hardware, software and other service technology company founded in 1911. classifies this function as optional
	if the POSTsee Power-On Self-Test determines that the timer is nonfunctional, this function
	  uses the 15.025 microsecond refresh timer instead of the
	  full-resolution timer
