I just thought I would share some info that I just found out regarding the A8N32 and booting from a usb key.

Im not sure if this is true in every bios version but in version 1009 once you format your usb key and try to boot the bios will auto configure your key depending on the size of the key. My key is 1gb so it gets set up as hard drive emulation.

The problem with my setup was that it would not boot off the key - i had to go into the hard drive boot order and move the mini cruzer to postion 1 in order to boot from it - even though there is a boot order menu.

I didnt test it but i bet if the key was set up as removable or floppy i would have had to go into the removable boot order and move it there to position 1 to boot - even though it may be selected as the first boot device in your boot priority menu.

Hope that helps someone else out from wasting time trying to get this mobo to boot in the order you pick.
