TLIVESA.COM USAGE:
==================
TLIVESA.COM is the VESA Super VGA Bios Extension driver
for Compaq Prolinea 486 systems using the Tseng Labs ET4000
video chip.  Version 1.2 of the VESA specification is
implemented. It is a terminate-and-stay-resident program
which intercepts the video bios interrupt vector to provide
additional bios commands supporting super-VGA modes.

To load, just give the command:

        TLIVESA

TLIVESA may also be unloaded again, freeing the memory,
provided no other resident program which intercepts the
video bios interrupt vector is loaded afterward. (Actually,
no resident program at all should be loaded afterward in order
to really free the memory.) To unload, give the command:

        TLIVESA U
