Gigabyte B450 Question

[kiddagoat]

My brother has a B450 AORUS ELITE (rev. 1.x) motherboard. I put this motherboard in with the rest of his current system about 3 years ago now.

B450 AORUS ELITE (rev. 1.x) Support | Motherboard - GIGABYTE Global

Current BIOS on the website is F64c.

The current BIOS on his motherboard is either F30 of F31.

In the past I remember you had to update each version in succession until you got to the latest one. It's been a while. Is that still the case?

He's been getting some weird boot device not found issues with his system. I checked and both NVME drives are there. It appears the boot order got switched somehow. When I put the boot order back, it boots fine. I am wondering with time, drivers, and updates, would an older BIOS start to have issues?

On Ryzen, you generally don't get any performance improvements through AGESA once the next gen of CPUs is released. Unless there's something specific you need in newer AGESA (ie. more fleshed out Secure Boot and fTPM settings for Win 11), best not to fix what ain't broke.

As for BIOS update order, I'd reach out to Gigabyte and ask. A lot of vendors had to implement a convoluted update process around the Ryzen 3000 release (for Gigabyte B450 seems to be around the F40 mark), removing old CPU support and whatnot to accommodate new ones in the tiny 16MB BIOS chips they used in 300 and 400 series chipsets. Ryzen 2000 I'm guessing? For 3700X support on the B450I Aorus Pro Wifi I had to do a few updates in a row to get to F42c.

As for the boot device not found, I can't think of any reason boot order would affect it unless maybe the Windows install is non-UEFI/MBR, which it should never be? With a UEFI install of Windows, it doesn't matter whether the partition table stuff is on the same drive as the Windows install, as long as it can find the partition table somewhere to enable it to boot, boot order should be irrelevant unless you have more than 1 OS in the system.

If you suspect BIOS corruption over time might have caused it, you could always just reflash the same BIOS. Although, Gigabyte is a little weird, I always find that flashing the same file is a lot faster than flashing a different BIOS, I'm not sure if it's actually doing all the work or cutting corners.

Usually a person doesn't have to go to each newer BIOS version unless there is a warning saying so.

However, say, in your scenario, it has F30 and F41 requires you to flash to F40 prior to flashing to F41, then yes, I would strongly suggest going to the prior "required" BIOS before flashing to anything newer.

Hmm, does that make sense?
