External Hard Drive and Boot Issue

I built a new machine any everything works great unless my external hard drive is plugged into the USB port. When it is plugged in, on boot up the computer will tell me that it can't find a hard drive. If I un plug it and boot its fine. If I plug it in after boot up, it works fine. I can't figure out why I can't leave it plugged in? Is this a setting in CMOS? Please Help?
I am running the following hardware.
ABIT AN7
AMD 3200
512 DDRAM 3200
Seagate 120G 7200 SATA Drive
Windows XP Pro

Your bios setting?

"
In the CMOS there are a couple of settings for the USB controller which are labeled as legacy 1.1 support. I figured that meant that unless enabled, the USB ports would operate in 2.0 mode only. According to the motherboard manual, which I should have read -- but real men don't read manuals Happy -- says that it's for providing USB support to OSs that don't support USB, like DOS. I disabled those options and things are once again working. "

2 ideas.

1. Make sure you've checked the Abit website for:
a. Latest BIOS.
b. Latest Motherboard and USB 2.0 drivers.

2. See if http://www.usbman.com notes this issue.

3. Not so much an idea, but my externals didn't work super until I put SP2 on XP.

Thanks for your help. My version of XP Pro was just bought and already has SP2. I will look for bios updates from Abit. Bios Updates are real easy to do these days, unlike they used to be. Thanks for the other website info!
