BIOS1352.COM UTILITY
BIOS1352 is a DOS 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 SED1352 is not a VGA or EGA compatible controller, this program is supplied to give the user a familiar prompt.
Within limits BIOS1352 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.
