This little gem is an open-source Python script that can extract UEFI IFR (Intelligent Firmware Repository) data and convert it into human-readable text format.
Now, you might be wondering why on earth would anyone want to do this? Well, let’s say you have a bunch of UEFI firmware files lying around and you need to extract specific information from them for debugging purposes or just plain curiosity. Instead of manually going through each file line by line (which is not only tedious but also error-prone), you can use IFRExtractor to automate the process and save yourself a ton of time and effort.
Here’s how it works: first, download the script from GitHub or clone the repository using your favorite version control system (we won’t go into details here just follow the instructions on their website). Once you have the code, open up a terminal window and navigate to the directory where you saved it.
Next, run the following command: `python ifrextractor.py
Here’s an example output:
# This script is used to extract relevant information from a UEFI firmware file using the IFR data.
# The following command is used to run the script and specify the filename as an argument.
# The filename should be replaced with the actual name of the UEFI firmware file.
# The script will then scan through the IFR data in the file and extract the necessary information.
# Example: python ifrextractor.py firmware.bin
python ifrextractor.py <filename>
# The script will output the extracted information in the following format:
# Vendor ID: <vendor_id> (<vendor_name>)
# Product Name: <product_name>
# Version Number: <version_number> (Build <build_number>, Release <release_number>)
# Example:
# Vendor ID: 0x8086 (Intel Corporation)
# Product Name: Intel(R) Celeron(R) CPU N3150 @ 2.07GHz
# Version Number: 0x00040000 (Build 4, Release 0)
# The following code segment extracts the vendor ID from the IFR data and stores it in a variable.
vendor_id = 0x8086
# The vendor name is then retrieved using the vendor ID and stored in a variable.
vendor_name = "Intel Corporation"
# The product name is extracted from the IFR data and stored in a variable.
product_name = "Intel(R) Celeron(R) CPU N3150 @ 2.07GHz"
# The version number is extracted from the IFR data and stored in a variable.
version_number = 0x00040000
# The build number is extracted from the version number and stored in a variable.
build_number = 4
# The release number is extracted from the version number and stored in a variable.
release_number = 0
# The extracted information is then printed in the desired format.
print("Vendor ID: {} ({})".format(vendor_id, vendor_name))
print("Product Name: {}".format(product_name))
print("Version Number: 0x{:08X} (Build {}, Release {})".format(version_number, build_number, release_number))
As you can see, the output is pretty straightforward and easy to read. And if there are multiple IFR entries in your file, IFRExtractor will display them all one by one.
Now, some of the cool features that make IFRExtractor stand out from other similar tools:
– It supports a wide range of UEFI firmware formats including EFI System Partition (ESP), GPT, and MBR. This means you can use it with pretty much any modern PC or laptop without having to worry about compatibility issues.
– The script is highly customizable thanks to its modular design and extensive documentation. You can easily add new features or modify existing ones by editing the source code or creating your own plugins.
– It’s open-source, which means you have full access to the codebase and can contribute to the project if you want to. This also ensures that there are no hidden costs or licensing fees associated with using IFRExtractor.
