Try any PCI GPU. 2F seems to be GPU not found on AMI BIOSes.

So I make a brief summary, on the Compaq Camaro (Mitac 5114VU), using the RAM and the CPU K6-2-475, at startup on the post card some codes are displayed, but in short it stops on 2F 2E, but usually I do these boot tests, without any drive.
From what I understand instead, if there is no drive connected, it may not start (?).
But on my motherboard, despite trying many times to start, I don't have any video screen, I think I also tried with a PCI video card, thinking that the integrated one could be defective.
So I think I'll do it in the next few days, a short test, with some drives connected, using a Samsung HD, and a 1.44MB floppy player 💾, who knows if in this way, I can see progress, or even a BIOS screen on the monitor.?

I can confirm that the CAMARO starts without a floppy drive attached because I start mine a few times and it did display an error message

I attached a WD hard drive with 640mb with MS-DOS and it still freezes after trying to access the disk drive

The ram I used is the one shown .. i tried other rams and it always complained by not booting or failing the memory test
everytime it didnt like the ram it would display some random POST code

Let me know if you want me to do some measurements on my board to try to help troubleshoot yours

Thanks a lot Nuno
Today I recovered the motherboard, which I keep in a (self-built) file, it was very easy to find it, while in the past I had to search among various boards in different boxes.
I also recovered an old 4.3 GB Samsung HD 🇬🇧, I will only need this to try the boot, later I will use another one, probably of similar capacity and different brand, I just have to find a 40 PIN IDE cable, I have some 80 PIN, but I should have another 40 ones somewhere.
Since it will work without a floppy reader 💾, I avoid connecting it, eventually if you need it I have one ready that I use to reprogram the BIOS, but I probably shouldn't need it, I think it's possible that the failure to start, depended on the RAM, I tried some modules, but I don't think they were the same (or similar) to the one you use, I should have one in one of my PCs, unfortunately it won't be easy to find it, I hope to find it and at that point, if I'm lucky 🍀 I could solve it.
For the moment I wouldn't make some measurements, if this test with RAM and HD fails, or I get other post codes, maybe 🤔 I'll tell you which measurements could be needed, but overall the motherboard seemed very tidy to me, maybe first I can look at some points under the microscope, hoping to find something.

Yes, I'll try first with the RAM like Nuno's, with a 4.3 GB Samsung HD 🇬🇧, without a floppy player, then if it doesn't display anything on video, or doesn't change anything by locking on the same post card codes, I'll try it with a VGA PCI, I have to find a 40PIN IDE cable, then I would be able to do startup tests.
I hope to make some progress, or even to solve, clearly in this last case, I shouldn't worry about updating the BIOS, but I reflected that the failure, could be the result of a BIOS update that went wrong, I came across my paws 🐾, various motherboards with corrupted or damaged BIOS, unfortunately here the chip is welded, and for the moment it is a problem not a small problem.
