- EMBEDDED BIOS VIDEO SUPPORT
- ════════════════════════════════════════════════════════════════════════
- Just like a commercial desktop BIOS, Embedded BIOS provides support
- for ROM-less Monochrome Graphics Adapter (MGA) video adapters, as well
- as smart adapters such as CGA, EGA, VGA, and SVGA.
-
- As part of BIOS system initialization, Embedded BIOS attempts to locate
- and call a video ROM at location C000:0000, if present. If it is, then
- your own video adapter is initialized. Otherwise, the basic character
- output services are provided to write to memory at location B000:0000
- (monochrome) or B800:0000 (color), at your option.
-
- Of course, systems that don't have a display may use a COM port for
- screen output, or you can remove video BIOS functionality altogether.
- For details about I/O redirection, see the [Serial Port] topic.
