FailSafe Boot Block ROM
The FailSafe Boot Block ROM allows for system recovery in
the unlikely event of a ROM flash failure, for example, if a
power failure occurs during a ROM upgrade. The Boot Block is
a flash-protected section of the ROM that checks to validate the
system ROM each time 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. To use the ROMPaq
diskette, the Deskpro 4000N must be connected to a second
computer through a serial cable. In order to use the second
computer’s diskette drive as an external diskette drive on
the Deskpro 4000N, optional FDS software must be
installed on the second computer.
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.
