Messages
386_DEAD Displayed when the MFB’s main processor fails or is not able to
communicate with the Faceplate and Alarm Controller (FAC).
The FAC and alarm board processor can still be functioning. In
this state, it is safe to remove the DEFINITY LAN Gateway
system for repair.
BTEST Board Test — Whenever the system is reset, this is displayed
when flashware is performing a hardware initialization and test
on the MFB.
BOOT Displayed when the board test is complete and flashware turns
control over to the boot loader.

loader turns control over to the operating system or the booted

Brought up during OS initialization only if the system determines
that one or more of the 80386SX, faceplate and alarm controller,
or alarm board FPROMs must be reprogrammed.
Reprogramming is done automatically.
!
WARNING:
The system should never be shut down during the
reprogramming sequence. The MFB will have to be sent
back to the factory if programming is not allowed to
complete.
