3.4.10 FWH Flash Memory & Failover
The AMC-1000 is designed with two on board 8Mbit Firmware
Hub (FWH) devices for failover purposes, the BIOS1 FWH and
BIOS2 FWH. The system BIOS will be flashed to both BIOS1 and
BIOS2 FWHs at the factory. The BIOS1 device is the default boot
BIOS. If the BIOS1 FWH fails to boot, the system will trigger the
flash recovery procedure that will display the following messages
on screen, indicating that the contents of the BIOS2 FWH are
being copied to the BIOS1 FWH.
After the flash recovery procedure is complete, the display will
show “Booting BIOS1...” and then the system will reboot automati-
cally.
