Ivy Bridge gen board: H61M-USB3V
A customer wants a Windows 11 upgrade on this "unsupported" PC, and I felt that it was time to start using the 24H2 version as 23H2 is only supported until this October. During this upgrade attempt, four things were changed: The machine was configured to run in IDE mode so I switched it to AHCI and sorted out Windows to accept that, the Boot HDD was cloned and replaced with a SSD (so all my upgrade attempts were with the SSD), memory upgrade from 4GB to 8GB RAM (additional module added, memtest86 ran and passed 4 times no errors), and later during my attempts to do the Win11 upgrade I switched the system to UEFI (along with mbr2gpt on the SSD).

Win11 upgrade plans A, B, C and D all failed so I decided to unplug the PC and go back to a spare PC and try my latest idea on there. My latest idea worked, so I intended to start the process all over again on the customer's PC including a drive swap, re-clone the HDD, etc, with an overall plan to have that PC booting from BIOS as it always has done rather than UEFI (my logic being that if a computer has been reliable in a particular mode and there's no compelling reason to change it, and the change could cause problems down the road like I've experienced before with PCs made soon after the change to UEFI, and the change could be easily made later if need be, then if it ain't broke don't fix it).

So this morning I unplugged the SSD from that PC and reconnected the original HDD. I fully expected for it to throw a boot wobbly because MBR vs GPT, but what happened instead was that when the PC powered on, it beeped rapidly so many times that I wouldn't even bother to count it (20 beeps at least, the sort of rapid beep that is similar in tempo to the final beeps of a 'no graphics' beep sequence) then it auto powered down. I disconnected the HDD, switched it on again, it did the same beep sequence and temporarily showed a 'Dual BIOS' screen' I haven't seen before then auto powered off. I then removed the additional memory module and it either booted properly straight away or it did on the second attempt (I *think* it booted straight away, this happened first thing this morning and I wasn't expecting this drama). I then reconnected the HDD, switched from UEFI to BIOS mode and it booted Windows.

Since then I've added the extra memory module, done the clone, booted Windows from SSD, all is well. However, that beep sequence worries me. Any ideas? It's not running the latest BIOS, I *can* do that but I'm not a fan of BIOS updating unnecessarily plus to my knowledge this PC has never done this before so why now.

Reads like the bios was nerfed and the board loaded the backup copy.
Ok, more reason for me to think of replacing the CMOS battery, it's got to be ten years old at this point, and this computer has probably been unplugged (by me) for longer than it has been for a long time.

Would you expect the most recently-set BIOS settings to have been lost? It's just that it's apparently remembered the AHCI change I made. Admittedly I'm assuming that the original builder left the setting on the default which happened to be IDE (along the lines of 'low effort builder')...

Changing the battery is a good idea regardless. And as you have the system upgraded and playing nice, I'd take it as a win if it passes your stress testing.

The customer is a browser tab or two at a time kind of person *at best*. I suspect this computer will have passed on before >8GB becomes relevant to them.

So far so good, processor upgrade done (from i3-3220 to i5-3570), memory upgrade still in, SSD working fine, 24H2 installed, battery replaced (IDE mode was the default setting!), just running the processor through its paces with prime95. Surprisingly I found an updated graphics driver for the i5 so it's now got a 2020 version driver rather than 2015.
