From SPK, I get series of 3 long beeps, approx 2 sec apart, series repeating after approx 5-6 secs. I am however not familiar with error beep codes on this board, and could not find any info on them Could this be related to the fact that there are no L2 Cache chips on-board? From the manual, there …

It has the AMI BIOS chip still on it and I could look into extracting the image. Only one problem: how do I do that? Give GETROM a try, it's a DOS utility used to extract BIOS images. http://cd.textfiles.com/microhaus/mhblackbox3/MEMORY/GETROM.ZIP If you obtain the BIOS image, let me know, so I can …

If you can get the board to boot, try GETROM http://cd.textfiles.com/microhaus/mhblackbox3 … MORY/GETROM.ZIP Another good alternative is to use an EPROM reader (like the TL866), that works just as well.

Try to reverse engineer the area around the transistor, it should be a general purpose 2N3906 or 2N 3904 (PNP or NPN). Depending on how the transistor is connected to the power rails/if the base is pull up or down, you should be able to identify the type needed.

So, I have a strange board for which I cannot find the manual. It's an Aries _3P, DOC: 14760, which has a Socket7 slot marked with P54C. I have a strong feeling of this being an FIC motherboard, given the model number on the PCB, but I have no info on it yet. Could you please take a photo of the …

I'm guessing putting 48W Delta fans inside a small computer has no practical reason, other than looking badass. Connecting just one of them to that controller will make it let out the magic smoke. Even at 5V, I don't think it can handle them. Your best option is to hot wire them on 5V directly or …

Still... same - doesnt match! My mobo (if agreed with Your pin countage method) is set to 7-8 at JC1 Yes? Refering to the Manual, it should be then a 486 SX/DX CPU! I don't have but SX/DX - I have installed DX4.... It's simple, you need to add the extra jumper on JC2 pin 13&14 and the extra ones on …

If you start counting from pin 2, it matches with the printed manual. Have a look at the DX/SX jumper patterns, you'll see that they match. It is possible the printed manual is based on a earlier/later revision of the PCB, compared to the MTL manual. Filename a.png File size 1.07 MiB Views 140 …

Aftet quick analyse of the manual I've encountered that it is not coresponding to this MB: - In section cpu type setrings: JC1 for example has 14 pins and my mobo has 20, JC2 in manual 14 pins in mobo has 16 So sadly I think it's not that MB. It's VERY similar at first look, but it's different mobo …

Given the brutal state of the PCB components (the CPU socket is literally ripped in half lmao), I would also carefully analyze the state of the traces in the damaged areas. Have you tried measuring that damaged SMD resistor ?
