ROM on individual PCs through a Windows operating system.

The FailSafe Boot Block ROM allows for system recovery in the
unlikely event of a ROM flash failure, for example, if a power
failure were to occur during a ROM upgrade. The Boot Block is
a flash-protected section of the ROM that checks for a valid system
ROM flash when power to the system is turned on.
■
If the system ROM is valid, the system starts normally.
■
If the system ROM fails the validation check, the FailSafe Boot
Block ROM provides enough support to start the system from a
ROMPaq diskette, which will program the system ROM with a
valid image.
When the bootblock detects an invalid system ROM, the System
Power LED blinks RED 8 times, one every second, followed by a
2-second pause. Also 8 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,
complete the following steps:
1. If there is a diskette in the diskette drive, remove the diskette 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.
