NOTE: Some models also support recovery from a ROMPaq CD. ISO ROMPaq images are included with
selected models in the downloadable ROM softpaqs.
When the boot block detects an invalid system ROM, the power LED blinks RED eight times, one every
second, followed by a 2-second pause. Also, eight simultaneous beeps will be heard. A Boot Block
recovery mode message is displayed on the screen (some models).
To recover the system after it enters Boot Block recovery mode:
1. If there is a diskette in the diskette drive or a CD in the CD drive, remove the diskette and CD and turn
off the power.
2. Insert a ROMPaq diskette into the diskette drive or, if permitted on this workstation, a ROMPaq CD into
the CD drive.
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.
4. Enter the setup password.
If the system successfully starts from the diskette and successfully reprograms the ROM, then the three
keyboard lights will turn on. A rising tone series of beeps also signals successful completion.
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.
