About the VESA Test Program
---------------------------
The Cirrus Logic VESA Driver test program exercises the
VESA Driver by making function calls into the driver and
displaying the results.  The test program exercises VESA
functions 0 through 7 as described in the VESA Super VGA
BIOS Extention Standard #VS900602.  This document may be
requested directly from the VESA office (408) 971-7525.

If the VESA Test Program is run on a flat panel, all modes
should return a failure code except VESA Mode 0x108, this
is the only mode that will correctly run on the flat panel.

Note that in order for the test to run correctly, the
Monitor Parameter Utility that will support all the modes
must be loaded.
