[comp.sys.ibm.pc.hardware] ATI VGA-Wonder Programming Information wanted

pgd@bbt.se (P.Garbha) (08/09/90)

I have an ATI VGA-Wondercard (1024) and is looking for programming
information for it. In the "PROGINFO.DOC" it says how the memory is
organized, but what i im looking for is information about differences
between the ATI Wondercard and normal VGA. What values to put into the
extended registers?
Specifically i am looking for information on how to setup the card
directly on the hardware level. (Becuase i am using unix, the BIOS is
no accessible.)

I made a small program to setup a video mode with int 10, reads all
the hardware registers, and puts the values in a files. With a similar
program it is possible to read the dumped values and re-program the
registers again. It works, except for the 800x400 and higher modes.
It seems like I am missing something with the extended registers. Are
they fully readable and re-programmable?

Does anyone have any information regarding the card?

Um, no I dont have any info. But as long as we're on the subject of
ATI video cards..... I have the ATI card that comes with the GATEWAY
2000 systems.   It has 512k ram capable of 1024x768.  I want to know 
that, if and when drivers come out that support 1024x768 in 256 colors,
will I need 1 meg. of ram instead of 512k and if so, will this card accept
1 meg of ram????
