asus_tools

An unopinionated Asus Bios Renamer shell script.

Prerequisites

You'll need access to a bash-like shell with the following binaries grep, strings, tail. These, should, be present in almost any bash like environment.

Using This Script

Clone this repo

1. open a terminal in the cloned repo directory
2. copy the target bios file SomeFile.CAP and the BiosRenamer.exe to this directory
3. mark the script as executable

chmod u+x ./bios_renamer.sh

4. execute the script from the terminal

./bios_renamer.sh

How The Script Works

The expected file name is recorded in this rename binary. This script fetches all strings from the binary, looks for .CAP, then renames the original .CAP file.

Why This Repo Exists

• Access
  • Doesn't require Linux (should work on MacOS, FreeBSD)
  • Doesn't require Windows or emulation (e.g. WINE)
  • Doesn't require x86
• I'm opinionated
  • A binary to rename a file is absurd
  • ASUS could just ship this with the appropriate name
  • ASUS could leave instructions in plain text
  • Other tools appear to be overly complex and expose individuals to supply chain attack

Technical Note

The diff of the original file and the renamed file is empty, and SHA256 sums are identical for the ASUS provided binary, and likewise for this script.
