Problems with Matrox Mystique in 1000A

[Dan Williams]

Hi,

In my AS 1000A 5/400, I've put a Matrox Mystiqe with 4MB of VRAM.  Its 
got the 1064SG chip, which is supported by X11 and the mga accelerated 
driver.  However, XFree86 under both 1024x768x16 and 800x600x16, I get 
_bad_ graphics corruption, consisting of vertical yellow lines down the 
screen in all windows and graphics elements.  Of note is that this card 
is from a PC.  Is there anything I can do about this?  Is it something 
Alpha or bus speed related?  Should I try another slot?  Its in the 
slot the original card was in...

I had tried to run X with the supplied 1MB Number Nine Trio64+ card, 
but that ended in failure as the machine never actually brought up the 
display in graphics mode (still was in text mode with gibberish) and 
whenever I pressed Ctrl+ALT+Backspace to exit the X server, the machine 
paniced with a "sense code 0x8e <something>" error.

I happen to have a Dell card, but its also a Trio64+ and I'm not sure 
it will work well. What video cards have people gotten to run perfectly 
find in their AlphaServers?

Thanks,
Dan
