INT 10 - VESA(Video Electronics Standards Association) An industry group which sets both hardware and software standards and recommendations. The term VESA is also used to denote compliance with the VESA SuperVGA BIOS Extensions, a standard set of video BIOS functions for accessing video modes of higher resolution than those defined by IBMInternational Busiuness Machines. SuperVGA 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. v2.0+ - GET/SET PALETTE ENTRIES AX = 4F09h BL = subfunction 00h set (primary) palette 01h get (primary) palette 02h set secondary palette data 03h get secondary palette data 80h set palette during vertical retrace CX = number of entries to change DX = starting palette index ES:DI -> palette buffer, array of 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. entries (see #00086) Return: AL = 4Fh if function supported AH = status 00h successful 01h failed SeeAlso: AX=4F0Ah,AX=D000h"S3VBE" Format of VESA(Video Electronics Standards Association) An industry group which sets both hardware and software standards and recommendations.
