To upgrade the ROM, download the latest ROM BIOS image from the HP Web site (www.hp.com) and follow the online instructions. The 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 1. Remove any bootable media from the computer and turn off power. 2. Insert a flash drive or CD containing the ROM BIOS. 3. Turn on power to the system. 4. The system will automatically flash the ROM. After a successful flash, the system will either automatically restart of prompt the user to unplug the unit, wait 5 seconds, reattach the power cord, then press the power button.

Reconnect the power cord to the power source and start the computer. Clearing CMOS To clear CMOS using F10 Computer Setup Enter F10 Computer Setup and press F5. This will reset all BIOS setup options to their default values. This will not update system date, system time, supervisor password, or user password. To clear CMOS using system board jumpers 1. Shut down the computer and disconnect the power cord from it power source. 2. Move the CLR_CMOS jumper from pins 1 and 2 and place it on pins 2 and 3. 3. Wait 30 seconds before returning the jumper to its normal position. 4. Reconnect the power cord to the power source and restart the computer.
