INT 10 - Chips & Technologies Extended 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. - RETURN CHIP INFORMATION
	AX = 5F00h
Return: AL = 5Fh function supported
	    BL = chip type (see #00176)
	    BH = video memory size (see #00177)

 0	DAC(Digital-to-Analog Converter) A hardware device (in its simplest form, nothing more than a set of interconnected resistors) which converts a digital number into an analog signal whose voltage is proportional to the value of the digital number.  VGAVideo Graphics Array and later color video boards use DACs to convert color values into the analog signals sent to the display; sound boards normally use DACs as well. size (0=6-bit, 1=8-bit)
 1	system type (0=PCIBM PC/ATIBM PC AT, 1=PS/2IBM PS/2, any model)
 2	extended text modes supported by 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.
