To recover the system after it enters Boot Block recovery mode, complete the following steps:
1. Remove any diskettes from the diskette drive and turn off the power.
2. Insert a ROMPaq diskette into the diskette drive.
3. Turn on power to the system.
4. If no ROMPaq diskette is found, you will be prompted to insert one and restart the computer.
5. If a setup password has been established, the Caps Lock light will turn on and you will be
prompted to enter the password.
6. Enter the setup password.
7. 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.
The following table lists the various keyboard light combinations used by the Boot Block ROM,
as well as the meaning and action associated with each combination.
