Z790 Hero does not remember boot order.

I've got a Z790 that resets boot order every single boot.

I want to boot from  PCIE not m.2.  

I expressly disable booting from m.2, and it does it again!

I'm on the latest bios.  (4/17/2024 - 2202)

If you are on BIOS defaults anyway, it's possible that the motherboard battery has expired and you haven't realised. Cheap to replace, probably worth a try...

Z690 Hero, 12900K, BIOS 3501, MEI 2406.5.5.0, ME Firmware 16.1.30.2361, 7000X Case, RM1000x PSU, ASUS TUF OC 3090TI, 2 x 16GB Corsair RAM @ 5200MHz, Windows 11 Pro 23H2, Corsair H150i Elite AIO, 4x Corsair RGB fans, 3x M.2 NVME drives, 2x SATA SSDs, 2x SATA HDs.

Wouldn't it lose other settings as Walton not just the boot order? In any case I'll give it a shot but I'd be surprised if it works. Also that would probably require it to be turned off from the PSU or unplugged to lose settings.

It would, that's why I said "if you're on default settings". So probably not the battery then, but it seemed like a possibility when I thought of it. I've never booted from a PCIe device, so have no direct experience why that might be happening, sorry.

Tried replacing the battery, still doesn't help. 😕
