by I just bought a Creative Labs Graphics Blaster MA202 as an upgrade to my
PCI noname video card (with Cirrus Logic 5434 chip). The Graphics
Blaster has a Cirrus 5446 chip and a great price. However, my system
won't use it. Immediately on power up I get 1 long beep followed by 3
short beeps. The display comes up corrupted, with a number of vertical
bars of random charaters across the screen. I used an old version of
Checkit under a DOS session to test the video memory and received
numerous memory parity errors. I then experimented with motherboard
settings, including specifying the system memory was EDO, but nothing
worked. I have 32 megs of standard, fast page mode ram on a 486 PCI
motherboard, AMI BIOS, AMD 133 cpu overclocked to 160.
I took the board back and exchanged it on the off chance that it was
defective, but the new board did exactly the same thing.
It now occurs to me that I can't mix EDO video ram with FPM system ram.
I would like to know if anyone has run into this problem and if changing
system ram to EDO would fix the problem.
