To upgrade the ROM, download the latest ROM BIOS image from the HP Web site (www.hp.com) and follow the online GUI/instructions. How It Is Established Feature Purpose Floppy drive controller Prevents the transfer of data to or from the floppy drive. Setup Utilities Device Boot Disabling Prevents booting from and or all of these devices: Internal or external USB, Internal ODD, or Internal FDD Setup Utilities Security Option Prevents use of computer until password is entered. Can apply to both initial startup and restart. Setup Utilities 1. Remove any bootable media from the computer and turn off power. BIOS Write Protect Restricts ability to change ROM BIOS without approval. Setup Utilities. 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.
