Karen, as regards "parity" error messages, sorry, that's beyond me. If it's
a plug and play card, and drivers installed, and in correct slot, (and if
the system was fully stable before installation, and if it reverts to
stability with the card removed) - lot of "if's" - then logically it should
work, else it's a faulty card. To test - do you have access to another XP
machine to try it?
Other thoughts, before that step -
Did your card come with drivers (and did you install them?)
Which PCI slot did you use ? - shouldn't matter, but if it was the bottom
one (furthest away from the m/b) that might be the prob, as that slot may be
reserved for a sound-card by the m/b mfr. Try switching to another currently
"free" one.
There can be probs with power on USB cards (as opposed to m/b on-board
USB) - seen this elsewhere.
I use a 4 port hub connected to my USB2 2-port card, it won't even run a
memory stick without external hub power supply being connected, though
documentation rates it at 500ma (adequate for memory stick). Might explain
why yr portable hard drive won't work on this card - it needs power for the
motor as well as for the data interchange, so power need may exceeds card's
ability to supply it, and cuts out to avoid damage.
Looks like few MVP's are reading this thread. Try posting a new one with
subject header "parity errors with USB2 card" which might attract different
more experienced advice.
Sorry I've not been of more help.
Sincerely, Len

Hi,
Well, I unplugged all my USB devices went into the device manager and
uninstalled all USB things. When I restarted I got the same message as
before. This time I tried typing r to reboot and go into the setup and it
came back with a message saying an attempt at rebooting has caused an
error
[eNMI] so I tried again and that time it said the error was in [Vmgr]. So
I
shut down and physically removed the new USB card and rebooted again. I
unistalled all the USB junk again, shut down out the card back in and
restarted the computer and was right back with the same I/O card parity
error.. One thinh that I didn't realize until tonight though is that the
new
USB connection isn't really working like I had previously thought. If I
plug
my small portable hard drive into it it doesn't work on that. It does
however
work on a little 256MG flash stick. At first I thought maybe something had
happened to the small hard drive but it still works (slowly) on the old
USB
connection. This was the whole reason for getting the 2.0 USB card. if you
have any other suggestions I'd like to try them. Thanks,
-Karen

Karen, having installed a UDB2 card on top of USB1 very recently (and had
problems) advice I received was to go to Device Manager, UNINSTALL EVERY
INSTANCE of USB (and DO ensure you have a non-USB mouse/keyboard and that
you have disconnected all USB devices first)
Reboot, and XP will then detect and install both USB and USB2 correctly
Worked for me (the warning about disconnecting USB devices is VERY
relevant)
Hope this helps - do tell. Sincerely, Len
Hi,
I have just installed a Compaq 5 Port USB 2.0 PCI Host Card on my
computer
(Dell Dimension 8100, OS Window XP Pro) I already had USB 1 but have
devices
that required the faster USB. The new USB is working and there are no
yellow
marks in my device manager but when I startup my computer I get an
error
message the says I/O Card parity at F000:BB87 Type(S)hutoff NMI,
(R)eboot,
other keys to continue.
When I type S It than has the same message except instead of the
earlier
letters and numbers it is F000: 272B
So, I type S again and the computer than starts and acts normal. I
tried
an
earlier suggestion made on this site whereby I disconnected all USB
devices
and went into Device manager and uninstalled the USB connections, then
restarted and let windows detect the new hardware and install the
drivers.
This did not change it. I still received the same error at startup. Any
suggestions? Any help would be greatly appreciated. Thanks,
