     Being able to boot off of alternative media really comes down to
     whether the BIOS support it or not.  I can boot off a USB stick
     on my test cubes though I've noticed that the BIOS does not always
     properly reset the USB ports, causing it to not probe them sometimes
     on reboot.
Yes, I've seen that, and also with my USB mouse occasionally, but it happens
rarely so I don't know how to reproduce it.
