A couple of months ago I purchased a 5 port USB 2.0 PCI Host card for my Dell Dimension 8100. (OS Windows XP Pro). Ever since installing it I get an error when I reboot the computer. It says:
I[COLOR=Blue]/O Card parity interrupt at F000:BB87
Type(S)hutoff NMI, (R)eboot, other keys to continue
When I type S I then get this message:
I/O Card parity interrupt at F000:272B
Type(S)hutoff NMI, (R)eboot, other keys to continue
Then I type S again and the machine reboots and everything runs fine. The usb port works fine and there are no yellow marks in my device manager. There is no sign of any problem once I have rebooted. I wrote to the manufacturer of the card and that was pretty worthless. I have tried putting the card in a differrent slot and still got the same error. I tried uninstalling all the USB devices and starting over and that turned out the same too.
I was hoping maybe someone out there might have some ideas. I'm willing to try just about any suggestions. Thanks,

Welcome to the PC Guide Forums!! :D

Ah, this one again! And what a surprise - another Dell! :rolleyes: Take a look at this thread (http://www.pcguide.com/vb/showthread.php?t=32708&highlight=I%2FO+Card+Parity+Interrupt+Error), read it all if you want. Basically your solution is simply to update your BIOS. That seems to fix these "parity errors" on the latest high-end Dells.

Thanks, I already tried to update the bios but The Dell site says it is up to date. So I guess I will just live with the error message untill somebody comes up with another suggestion. I appreciate your trying to help though.

If the BIOS is already the latest one and you're still getting that error, I'm afraid you'll have to wait for Dell's next BIOS update for your system. So far I've only seen this problem on Dell PC's, so it must have something to do with the way they make their proprieatary architecture. Sorry we can't be of more help.

Are you kidding? You were the best help I have had on this problem. At least I know that it isn't something no one has ever seen before and you didn't just tell me to check to see if the card is in tight. For two months that's all the farther I got from the card manufacturer. I felt much better after reading all the postings that you directed me to. Thanks,
