In my humble opinion, the _need_ to install BIOS update is extremely bad flag on hardware manufacturer reputation. For ages I used Tyan system boards ("motherboard" jargon became the name for system board decades ago...) and never I had a problem to solve which it was necessary to install BIOS update. The requirement to install BIOS update is an indication that whichever BIOS version needs to be replaced should never have been released in the first place - not before is was debugged appropriately. Tyan is in small server board business forever. A bit younger Supermicro... well, I have a feeling that they indeed have flops with some "releases" of their BIOSes. Alas, Supermicro effectively displaced Tyan from US small server market. I had problems with some Supermicro boards, most notably boards for AMD Opterons (which "die of age" sometimes at rather young age: 4 -5 years or so, which I attributed to not too good PCB and/or electronics design of the board...). The only reasons for the need of newer BIOS I feel are justified are: enabling new features of some motherboard components and security patch, the last should be really rare in such small and simple programs as BIOSes. Sorry about rant (probably should have added tags...)
