5 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 containing 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.

To recover the system after it enters Boot Block Emergency Recovery Mode, complete the following steps:

1.Turn off the power.

2.Insert a CD or USB flash device containing the desired BIOS image file in the root directory.

NOTE: The media must be formatted using the FAT16 or FAT32 file system.

3.Turn on the computer.

If no appropriate BIOS image is found, you will be prompted to insert media containing a BIOS image file.

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.

NOTE: BitLocker prevents Windows Vista from booting when a CD containing the BIOS image file is in an optical drive. If BitLocker is enabled, remove this CD before attempting to boot to Windows Vista.
