Download the CSME System Tools v14.0.20+ from
Intel (Converged Security) Management Engine: Drivers, Firmware and Tools (2-15)
(You probably still have them since you used MEInfo)
Run …\Intel CSME System Tools v14.0.20+ r20\Flash Programming Tool\WIN64\FPTW64.exe -d spi.bin
That will give you a complete backup of the current firmware (24MB) without programmer.
Check the type of the two bios chips, especially if they’re 1.8V or 3.3 V type
Buy a CH341 programmer and a 1.8V adapter if those chips are 1.8V type
Buy an extra set of these chips, they’re normally cheap on bay. This way you could leave the original chips untouched.
If you don’t care use the original chips after having dumped the original firmware with ftpw!!
Take a stock bios, cut the capsule 0x0 - 0x1000, resulting file is exactly 24 MB 0x0 - 0x17FFFFF
Flash 0x0 to 0xFFFFFF on the 16 MB chip, flash 0x1000000 to 0x17FFFFF on the 8 MB chip.
If you may be ready to simply continue with the ‘new’ firmware you might transfer the board specific data:
- MAC Adress and some settings for the LAN card are in GbE region
Serial, UUID, MAC in bios region:
- ASUSBKP 0x964000 in padding
- 8C8CE578-8A3D-4F1C-9935-896185C32DD3 - SMBiosFlashData - Raw section
If you’re not sure if you prepared the stock bios correctly attach the files here.
