UEFIDump replaced by UEFIExtract with ‘unpack’ option

~ hucktech ~ Leave a comment

UEFITool is a Qt-based GUI tool that works on Mac/Windows/Linux. In addition to the main Qt-based GUI tool, the project also has a few other command line tools, UEFIExtract, UEFIFind, UEFIDump. And there are two codebases on Github, master and new-engine.

Some of the command line tools have been changing: UEFIDump was a tool that dumped info. UEFIDump is now gone, replaced by UEFIExtract with the “unpack” option (the “dump” option is related).

UEFIDump/UEFIExtract aside, UEFIFind is also useful to find information:

VbiosFinder and rom-parser

VBiosFinder: extract a VBIOS from a BIOS update.

This tool attempts to extract a VBIOS from a bios update.

Dependencies include: UEFIDump and rom-parser.

UEFIDump, of course, is included with UEFITool. But rom-parser is new to me.

To view ROM contents:
usage: rom-parser [ROM file]

This program does not have support for reading the ROM from pci-sysfs, please do this manually in advance, ex:
cd /sys/bus/pci/devices/0000:01:00.0/
echo 1 > rom
cat rom > /tmp/image.rom
echo 0 > rom

Pass the resulting image file as the argument to this program.
To modify ROM conents:
usage: rom-fixer [ROM file]
Obtain ROM as above, program prompts for modifying ROM vendor and device IDs and invalid checksums.
IMPORTANT: rom-fixer will update the ROM file in place. Make a backup!

UEFIDump created, UEFITool and UEFIExtract rewritten

Nikolaj has been rewriting his suite of UEFI tools, so they are no longer dependent on the Qt framework, and uses his new engine “NE” tag. UEFITool (UT NE) no longer requires Qt. UEFIExtract (UE) no longer requires Qt. UEFIFind (UF) still requires Qt, and will be ported later. UEFIDump (UD) is a new tool! Described below. Extract of release notes:

UT NE A30 | UE 0.12.0 | UD 0.1.0
Almost no new features, but massive changes under the hood:
* engine (classes from /common) can now be build without Qt.
* added support for very rare Apple-specific images.
* fixed some quirks with report generation.
* UT and UE binaries rebuilt to include updated engine code.
* UEFIDump utility released, it’s a PoC analog of UEFIExtract, that generates the same report and dumps all leaf items into one .dump folder without hierarchy, “_%03d” suffix is added for duplicated items. The tool is an example of Qt-less engine usage.
* UEFIFind will be ported to non-Qt engine a bit later.
