Better to have the motherboard doing what it does before an install. If a BIOS/UEFI firmware update changes any features, you'd want that done first. You'd like your kernel and its configuration to match your system. However... Always look at what an update offers, and whether there's been grievances posted about it. It's virtually impossible to revert back to a prior firmware installation. They usually don't offer it as a download, and if they do, the process usually refuses to downgrade. Sometimes you have a dual-BIOS system, where you update one, and the other is a fallback. Often it's bug fixes, maybe once or twice after sale, then it's abandoned. But sometimes you'll find that they've fixed something (that you don't care about), altered something else (that you also don't care about), and/or broken something (that you do care about). I have two indentical motherboards here, bought within a week or two of each other from the same store (I installed the same CPU, the same amount of RAM). They don't have the same firmware, any more, but should. They have the ability to self-update, if connected to a working network, and you go to into UEFI and initiate it (which is much better than having to install Windows to update it). One did it fine, the other has always refused to connect. I don't see any operational behaviour between them beyond that one won't do the update, and a bit of text on screen while it cold boots. -- uname -rsvp Linux 3.10.0-1160.119.1.el7.x86_64 #1 SMP Tue Jun 4 14:43:51 UTC 2024 x86_64 (yes, this is the output from uname for this PC when I posted) Boilerplate: All unexpected mail to my mailbox is automatically deleted.
