MSI LiveUpdate BIOS Grabber

Description

Parses MSI LiveUpdate BIOS update catalogs and saves all newer (since last run) download links into a text file. It removes any catalog formatting, ignores false positives, removes duplicate links and sorts them in alphabetical order for easy comparison afterwards.

Usage

The DB (i.e. MSI_BIOS_Grab.txt file) consists of all MSI LiveUpdate BIOS update catalog download links which have been gathered so far across all runs. Note that some of them may not work (e.g. 404), which is probably due to MSI mistakes/typos.

Compatibility

Should work at all Windows, Linux or macOS operating systems which have at least Python 3.7 support.

Prerequisites

To run the python script, you do not need any prerequisites.
