3.Turn on the workstation.
If no ROMPaq diskette or ROMPaq CD is found, you will be prompted to insert one and restart the workstation.
If a setup password has been established, the Caps Lock light will turn on (on PS/2 keyboard only) and you will be prompted to enter the password.

5.Remove the diskette or CD and turn the power off.
6.Turn the power on again to restart the workstation.
The following table lists the various keyboard light combinations used by the Boot Block ROM (when a PS/ 2 keyboard is attached to the workstation), and explains the meaning and action associated with each combination.
