Step 2. Set JP9 for FWH Boot Block Write-Protect
Setting this jumper to open will prevent the boot block area of the FWH
(FirmWare Hub) chip from being written data into such that it is write-
protected from unwanted or abnormal write activity.
Note: In some rare cases, the boot block area will need to be flashed to
complete the BIOS upgrade procedure. Setting JP9 to open will cause
incomplete BIOS update in that case.
