Diagnostic Tools
Because there is no video or hard drive support from the Boot Block ROM, the keyboard lights
communicate information. When the Boot Block detects an invalid system ROM, the system
sounds a series of beeps (one long and three short) and flashes the three keyboard lights.
To recover the system after hearing the FailSafe Boot Block beeps:
1.
Remove any diskettes from the diskette drive and turn off the power.
2.
Insert the System ROM Recovery diskette into the diskette drive.
3.
Turn on power to the system.
If a Setup Password has been established, the Caps Lock light will turn on.
4.
Enter the Setup Password.
When the system successfully starts from the diskette and reprograms the ROM, the following
three keyboard lights will turn on.
