Error Conditions and Messages
Failsafe Boot Block ROM
The computer comes with a reprogrammable flash system ROM (read only memory). To
upgrade the ROM, download the latest ROM BIOS image from the HP Web site (www.hp.com)
and follow the online GUI/instructions.

2. Insert a flash drive or CD containing the ROM BIOS in the root directory. The media must be
formatted using the FAT12, FAT16, or FAT32 file system.
USB Controller
Allows you to disable or enable all USB
devices.
Setup Utilities
Your system ROM includes a Failsafe Boot Block that is protected during the flash process and
allows the computer to be restarted in the unlikely event of an unsuccessful ROM flash.
If the system detects an invalid system ROM during the boot sequence, the Failsafe Boot Block
attempts to locate a valid BIOS image on removable media. To recover from the Boot Block
recovery mode complete the following steps:
Boot Block Recovery
3. Turn on power to the system.
4. The system will automatically flash the ROM.
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.
