Hi Klaus,

Problem solved. I swapped the ABIT motherboard for a Gigabyte Technology 
BX2000+. This is PCI 2.2 compliant and has 3.3V on the PCI slots. I've 
tested it and it works.

Just having AGP slots is no guarantee - the ABIT board has AGP and no 3.3V 
on PCI. However, it didn't claim any kind of PCI compliance at all in the 
documentation or on their web site.

I suppose if you are designing a consumer-type card that has to work in any 
PC it should regulate from +5V, but we don't sell our cards outside the 
system they are part of so we can simply select PCs that are PCI 2.2 
compliant. If it claims PCI 2.2 then the 3.3V is mandatory.
