ifrextract shows UNKNOWN Protocol on HUANANZHI-X99-F8
shiecldk opened this issue · 3 comments
Environment: MacBook Air M1, Apple Siliicon, ifrextract version 0.3.7
When extracting the stock HUANANZHI-X99-F8 UEFI BIOS (read from CH341A) with
./ifrextract ./X99F8_Backup.bin ./X99F8_Backup.txt,
it reports:
Input: ./X99F8_Backup.bin
Output: ./X99F8_Backup.txt
Protocol: UNKNOWN
error: Unknown protocol
and no file is output.
With the modified UEFI BIOS, CX99DE29.BIN, from https://github.com/BIOS-iEngineer/HUANANZHI-X99-F8-2021,
./ifrextract ./CX99DE29.bin ./CX99DE29.txt,
it shows:
Input: ./CX99DE29.BIN
Output: ./CX99DE29.txt
Protocol: UEFI;
however, ifrextract only putouts the Realtek Ethernet Controller report (see the attached file).
The files are attached here:

I have a same difficulty
That's.. normal I think?
Due to some happenstance, parsing the second image somehow can read directly 2851E234-20FD-4D1E-9041-DCB8F3025CAE (which is the realtek driver.. the first one has the same content inside 8D59EBC8-B85E-400E-970A-1F995D1DB587).
But you should feed the program with individual dxes, not the whole ass bios blob.
Yep, the tool is supposed to consume an individual binary file, not the whole BIOS image.
