I would first look in the bios for likely suspects, but I expect you

I definitely don't want to get involved in BIOS updates on somebody else's computer, but you may well be right! Anyway, instead of the PCIe card, I tried a VERY old PCI card, and it works perfectly. So, it looks like some crazy interaction between the BIOS and the NetMos 9900 chip on the PCIe parport card.


I did try turning off some options in the BIOS, and managed to completely turn off the PCI slots, but that was about the only effect I was able to have. This is the first time I've seen something this crazy. I can't imagine what function would be pinging the parport every 33 ms, unless it just didn't configure properly at all.
