The Howto (and Howto-Not) Corner

To enable keyboardless operation, you have to enable server mode in the BIOS.

1. download Computer Setup/VP and PC Diagnostics from http://h18007.www1.hp.com/support/files/Deskpro/us/locate/4_71.html
2. create the required disks in DOS or Windows
   
3. set the password jumper on the motherboard to enabled position.
4. enter BIOS setup with the disks just created (note that you only need disks #2 and #3)
5. choose Security Management
   
6. enable Power-on Password and then enable Network server mode
7. now you can remove the keyboard

Note that you have to enter the password to enable the keyboard. There will generally be no password prompt, just type the letters in and press [enter], if you get it right you'll be able to use the keyboard again.
