System locks/hangs when booting from usb drive

[jonnnny]

I've tried this with several linux distros on several usb drives.

Whenever I try to boot from a usb drive (or boot from hd but have a usb drive attached) the system freezes for 3-4 minutes.. then continues booting as normal.

Why?? Anyone else getting this problem?

Some of the BIOS updates address issues such as yours (I think). Check to see if you have the latest BIOS update. Or at least check for symptoms fixed with each BIOS update on the BIOS download page.
