To upgrade the ROM, download the latest ROM BIOS image from the HP Web site (www.hp.com) and follow the online GUI/instructions. Common POST Error Messages 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: Screen Message Probable Cause Recommended Action 101-Option ROM Checksum Error 1. System ROM checksum error. 1. Verify ROM, reflash if required 2. Expansion board option ROM checksum 3. Clear CMOS memory, reboot 3.
