INT 15 - SYSTEM - POINTING DEVICE 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. INTERFACE (PSIBM PS/2, any model) - SET RESOLUTION
	AX = C203h
	BH = resolution (see #00523)
Return: CF set on error
	    AH = status (see #00522)


(Table 00523)
Values for pointing device resolution:
 00h	one count per mm
 01h	two counts per mm
 02h	four counts per mm
 03h	eight counts per mm
