10.3.2 Saving BIOS.bin to the SBC
1. Copy the flashlnx utility and BIOS.bin to the SBC running MontaVista Carrier Grade Linux.
2. Execute “chmod +x flashlnx” to change the file attribute to executable form.
3. Execute “./flashlnx -b -zc BIOS.bin” to copy the BIOS.bin file to the FWH and CMOS.
4. Upon completion, perform a reset to ensure the new CMOS settings and BIOS are loaded.
Caution: To ensure that the BIOS.bin file is not corrupted, Intel strongly suggests performing these steps
before major deployment of any SBCs running in a live network environment.
10.3.3 Error Messages
The table below describes an error message that may occur while copying or saving the BIOS.
10.3.4 Synchronizing BIOS Image and Settings from FWH0 (Main)
to FWH1 (Backup)
Before upgrading the main BIOS (FWH0), a user can create a mirror image where it copies all the
operational codes and CMOS settings to the Redundant BIOS Flash bank. This is suggested to
ensure the user preserves a copy of the old BIOS image before updating the main BIOS.
The syntax “./flashlnx –m” can be used to initiate this transfer. Refer to the suggested method in
Table 96.
