[comp.sys.ibm.pc] ATI VGA Wonder upgrade

jewett@mcnc.org (Rusty Jewett) (09/01/89)

I just purchased an ATI VGA Wonder with 256K on the card.  I am interested
in upgrading the card with an additional 8 pieces of 41456 chips.

Does anyone know of a good source of these chips?  Are there any pitfalls
in doing the upgrade (i.e. support software not able to handle the additional
memory, bios not able to use the memory)?

Also, the highest resolution supported by the card right now is 640x480 in 16
colors. Also, 640x400 in 256 colors.  What new resolutions will the upgrade 
give me?  I'm hoping for 800x600 in 16 colors, as well as 800x600 in 256 colors
and 1024x768 in 16 colors.

Many thanks in advance!
Rusty
