OUTSTANDING / OPEN ISSUES:
--------------------------
640 x 480 24bit and 800 x 600 16bit at 85Hz in 
a 1 meg configuration with fast page DRAM requires
an MCLK of at least 55MHz due to memory bandwidth
limitations.

800x600 16 color is only available after loading
the SVGA driver included with Windows 95.  This is
Microsoft's driver.


MISCELLANEOUS NOTES:
--------------------
This driver uses FIFO settings configured for EDO DRAM.
