[comp.sys.ibm.pc.misc] Configuring an old XT for an EGA card.

sampson@ei.ecn.purdue.edu (John Sampson) (04/26/91)

I have an old XT and a Taxan 640 color monitor which I have been using with a
CGA card.  Recently I purchased a used AST-3G Enhanced Graphics Adapter.  I
am having problems getting this card to work with my system.  The computer will
boot, apparently recognizing the new card, but the monitor is not working 
correctly -- I get white horizontal lines in the top 1/5 of the display.  I 
have tried many settings of the configuration switch on the EGA card, as well
as changing switches 2,5,6 on the mother board of the XT.  Can anyone offer
any assistance via e-mail?  Thanks.
