Programmable Flash BIOS IC

(HP Authorized Service Providers Only)

The replacement BIOS IC will contain enough basic BIOS programming to boot the OmniBook. However, after replacing the IC, the BIOS must be reprogrammed. Hewlett-Packard prefers that the system is programmed with the latest BIOS for the respective OmniBook. The latest BIOS can be downloaded from the WWW (see Table 1 - Additional Resources on page vi).
