Installation hangs

I can't install Windows Vista. Setup hangs right after validating the CD code.

I have a Dell Dimension 8300 (3GHz, 1GB RAM) with the Promise RAID card
attached to two mirrored SATA drives. XP SP2 is installed on these drives.
Since I don't want to mess up my XP installation, I'm trying to install to an
external Maxtor USB drive (about 300 GB, with about 200 free).

If I go to the place where you can load drivers for RAID cards, I can see
that Setup recognizes the Maxtor drive. If I load the XP driver for the
Promise card, it can see the mirrored SATA drive as well.

However, after I correctly type in the CD code and tell it to continue, it
hangs. This happens whether I load the Promise drivers or not. (If I type
the CD code incorrectly, it tells me it's wrong.)

Vista cannot boot from a USB drive.
