I don’t have experience with MSI recently, but I’d be really surprised if you couldn’t flash a new BIOS off the system partition or FAT32 USB. You may not be able to update from Linux directly, but almost all motherboards I’ve seen support doing it from the BIOS interface.
I have a tortoise and he’s great. I wouldn’t necessarily recommend them for everyone, but if you like reptiles they have a lot going for them. Calm, quiet, low maintenance, vegetarian (no crickets, mice etc.) and have a lot of personality. If you take care of them they can be a friend for life.
I like to take mine into the yard in an enclosure and chill in a hammock nearby. He even likes to cuddle into the crook of my neck on the couch. Not exactly the most active pet, but his calming energy helps my anxiety. When he’s splooted, basking under a heat lamp I am almost envious.
