Start of heading level 2: MSI MS-7673 BIOS Update to v6.20 with FreeDOS: Pitfalls and Solutions End of heading.
Sometimes computer archaeology catches up with you faster than you’d like. In my case, it was my mother’s computer (“MuttiLinux”)—a rock-solid machine powered by an MSI PH67A-C43 (B3) motherboard (internal model MS-7673) and an Intel Core i5-2500K (“Sandy Bridge”). The system had been running Linux smoothly for years, but on the firmware side, it was effectively frozen in time: BIOS version 2.70 from 2012.
Because newer Linux kernels and modern graphics cards run significantly better with proper UEFI support and up-to-date firmware, the decision was made: the final BIOS update to version 6.20 had to be installed. However, this version leap is anything but a routine update—and getting there gave me a genuine 30-minute heart-stopping moment.
