Here is some more info:

The file I copied to the USB stick was

ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/ISO-IMAGES/8.0/8.0-RELEASE-i386-memstick.img

Actually, I don't remember how I got the image to the USB stick. I 
believe I used a free tool from HP
 from within Windows XP.

I will try out your method below now.
