Hi, the offset 0x102 that I need to change, is from the 4KB file “Descriptor Region.bin” ? Here this offset is set to 90 (this is a download bios file)
With my dump.bin the offset 0x102 is set to 91 on the file flashregion_0_flashdescriptor.bin that I extracted using ifdtool, and then I ran the command “ifdtool -p sklkbl -M 1 flashregion_0_flashdescriptor.bin” but the output file is identical, so the value 91 is the disabled option (enabling changes to 90, disabling again changes to 91)?
Then I have the folders extracted using “generatedelta.py --input --output data/delta/”
My main goal here is to use a i3 9100 on my dell 3050 SFF, I was able to change and disable ME and apply the microcodes using coffetime, but every other modification made the system unbootable, with the front case led’s throwing me the error “Bios Checksum Failure”
So, back to running the scripts, running the final script “./finalimage.py --delta data/delta/dellbackup --version 11.8.77.3664 --pch H --sku 5M --fake-fpfs data/fpfs/zero --input 11.8.77.3664_COR_H_DA_PRD_RGN.bin --output patched-11.8.77.3664_COR_H_DA_PRD_RGN.bin” gave me some errors, and by viewing the exploit.py I found the issue, only the ME version 11.6.0.1126, with the combinations pch type and sku “H, 2M”, “LP, 2M” and “LP, 5M” are supported by this exploit, and my current desktop should be “H, 5M”, right?
So I will try using the provided ME donor images in the libreboot/deguard and after generating the new me file do I need to use this guide Clean Dumped Intel Engine or is there a easier way?
