Boot Block Emergency Recovery Mode
Boot Block Emergency Recovery Mode permits system recovery in the unlikely event of a ROM flash
failure. For example, if a power failure were to occur during a BIOS upgrade, the ROM flash would be
incomplete. This would render the system BIOS unusable. The Boot Block is a flash-protected section
of the ROM that contains code that checks for a valid system BIOS image when the system is turned
on.
●
If the system BIOS image is valid, the system starts normally.
●
If the system BIOS image is not valid, a failsafe Boot Block BIOS provides enough support to
◦
search removable media for BIOS image files. If an appropriate BIOS image file is found, it is
automatically flashed into the ROM.
◦
start the system from bootable removable media that automatically invokes system BIOS
upgrade utilities.
When an invalid system BIOS image is detected, the system power LED will blink red 8 times, one blink
every second. Simultaneously, the speaker will beep 8 times. If the portion of the system ROM containing
the video option ROM image is not corrupt, Boot Block Emergency Recovery Mode will be displayed
on the screen.
To recover the system after it enters Boot Block Emergency Recovery Mode, complete the following
steps:
1. Turn off the power.
2. Insert a diskette, CD, or USB flash device containing the desired BIOS image file in the root
directory.
NOTE: The media must be formatted using the FAT12, FAT16, or FAT32 file system.
3. Turn on the computer.
If no appropriate BIOS image file is found, the failsafe Boot Block BIOS will attempt to start the
system from a bootable device. If no bootable device is found, you will be prompted to insert media
containing a BIOS image file or BIOS upgrade utility.
If the system successfully reprograms the ROM, the system will automatically power off.
4. Remove the removable media used to upgrade the BIOS.
5. Turn the power on to restart the computer.
