Compaq deskpro won't reboot

Following up on a *very* old post of mine (to current@) which I still get
asked on:

This is fixed by doing two things:
 - enabling a jumper on the motherboard
 - updating the BIOS

BIOS updates are available from HP. Find them by searching for the BIOS
version. This shows up in the BIOS menu which you active by holding F10
during power-up. It will be something like "686T3" or "686T5". For example:

http://h18007.www1.hp.com/support/files/Deskpro/us/locate/20_123.html
http://h18007.www1.hp.com/support/files/deskpro/us/download/9249.html

The download creates a floppy disk, which you then boot from. It will back
up your current image (although you can do this yourself from the BIOS menu
as well) and flash the ROM.

Big thanks to Jason Lingohr <jsl at apache.org> and Brian Booth for helping
with this.
