	The PC I am using is has got a card and monitor with SuperVGA
capabilities but I find that I cannot use the extended VGA modes that it
is supposed to support. I have a program (called ADAPTER.EXE that came with
SVGA111) that determines what type of card you have and what display resolution
you can display. It shows that the computer will display 320x200x256 and 
640x400x256 but the latter does not work. The manual for it displays an
On Board VGA Jumper Select table that give three different alternatives.
It is currently at the 'Software Control' setting and has two more that
are 'Hardare Enable' and 'Hardware Disable'. Should this jumper be set to
'Hardware Enable' to obtain the extended modes or is it another problem?
The BIOS is Phoenix 80386SX ROM BIOS Version 3.01. Could this be the reason
why the extended modes do not work?
