Obselete 158649-003 programmable server keyboard

[BR741456]

We have a Compaq server keyboard with a 'wizard' kay and 9 'PC' keys which are assigned to different servers, the code 158649-003 is the compaq code for the keyboard, but no-one here can remember how to put the keyboard in programming mode, HELP! Does anyone else have one of these keyboards, or does anyone know how to put it into programming mode and get the on-screen menu up!!!??? All I can find on the web is 'quickspec' information, I cannot find a manual for the keyboard.
