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.
