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).

• 5mm hexdriver (OB5500 and OB5700 only)
• BIOS Insertion/Removal Tool (F1371-60904)

At a later date, the OmniBook 5700 will be compatible with the OmniBook 2000’s Lower Chassis Case.
At that time, removal of the Logic PCA will not be necessary to gain access to the Flash BIOS IC; it will be
accessible via the Flash BIOS Door as seen in Figure 42.
