13503BIOS.COM UTILITY
13503BIOS is a Terminate and Stay Resident (TSR) program which replaces and/or supplements the PC video interrupt
INT 10h. This program provides text, scroll, and cursor functionality when no VGA BIOS is present. Although the
S1D13503 is not a VGA or EGA compatible controller, this program is supplied to give the user a familiar prompt. Within
limits 13503BIOS simulates a VGA BIOS and will allow standard output functions to work. DOS programs such as Edlin,
Format, Debug, and internal commands such as Copy, Ren, Mkdir, etc., should work. However, complex programs such
as Edit, Qbasic, and Scandisk will not work. The standard output functions are handled by the VGA BIOS, if present.
