Synchronizing EFI BIOS Image and Settings from FWH0 (Main)
to FWH1 (Backup)
Prior to upgrading the main EFI BIOS (FWH0), a user can create a mirror image where
it will copy all the operational codes and CMOS settings to redundant EFI BIOS Flash
device. It is suggested the user preserves a copy of the old EFI BIOS image prior to
updating the main EFI BIOS in case FWH0 update fails.
The syntax “./flashlnx –m” can be used to initiate this transfer. Refer the suggested
method in
Suggested EFI BIOS image synchronization method prior to EFI BIOS upgrade
Copying and Saving EFI BIOS (Including CMOS Settings)
The EFI BIOS settings (CMOS), together with the EFI BIOS binary image, can be copied
to a file with a file name specified by the user. This feature is useful if you wish to use
one standard configuration of EFI BIOS settings across multiple MPCBL0050 boards.
Copying BIOS.bin from the SBC
Note:
1. Copy the flashlnx utility to the SBC. This SBC is the one with custom BIOS options

Command
- This is the original FWH images before an upgrade.
- FWH0 has Image N installed, which is a newer image
than what is installed in FWH1, which is Image N-1.
User can initiate a EFI BIOS update while the OS is
running.
When this command is executed, the Image N in
FWH0 (EFI BIOS codes + CMOS settings) is
synchronized to FWH1. Image N has now been copied
to the backup FWH1 EFI BIOS image
No reboot is needed for this operation.
When this command is initiated, the FWH0 image will
be updated to the latest version (Image N+1).
The latest version of the EFI BIOS will take effect after
the user initiates a reset.
If a checksum error is detected on FWH0 after a
reboot, it will automatically switch to FWH1 and regain
normal operation.
