I was wondering what are the top 10 failure modes for Voodoo2 cards?
I have a Diamond Voodoo2 12 MB card that has been sitting in my box of dead PCB's for a number of years now and decided it would be a good time to figure out what's wrong with it. The initial symptoms were such that Windows 98SE wouldn't even detect a PCI Multimedia Device. So I started to poke the pins on one of the QFP chips to see if I could easily break them free from their solder pads. 3 such pins moved without any effort on the 500-0009-01 chip. I brushed on some flux and took a fine soldering iron tip and reflowed them. I also reflowed several other adjacent pins because the flux was already there.
Putting the Voodoo2 card back into the system, Windows 98SE now sees the card and I install the drivers. However, I receive an error, _GlideInitEnvironment: glide2x.dll expected Voodoo^2, none detected. I've placed a know working Voodoo2 into the same system and it works fine, so I don't think there is a configuration or driver issue.
What are some other common failure modes on these cards? Should I reflow all the pins on the 500-0009-01 chip? What about the two 500-0010-001 chips? Does the AS2830 voltage regulator commonly fail? How about the GENDAC ICS5342 clock generator? I checked all the caps and none were shorted.
A scan of the card is attached below.
