Here the original BIOS
I checked your dump bios(is it??).
It already unlock "CPU/BIOS , Manageability Engine(me) , GbE Lan" to 0xff ,so it can read or write at will by INTEL FTP TOOL.
On my experience on my hp 3330 sff motherboard , i need desoldering chip from board and unlock it MEI area,then i can write it or backup complele bios(8mb) by fpt tool.
Original bios limits write bios by any tool.
This is my mod for 3330 sff.
