Something strange is happening to my CRT screen😅 I wanted to use it again after being unused for a long time, but the image is shaking all the time. I've tried using different cables, connecting it to different power sources, but it doesn't seem to work. Maybe there's nothing I can do about it. Here …

Run diskpart as administrator and use the clean all command. That should wipe out all the partitions and give you a fresh start. When I runned Diskpart and looked for the disk attributes, the "Read-only mode" didn't appear as active. I don't know if I messed up something inside the disk functioning …

Hi everyone! I'm having an issue with a CF card that I've recently bought, and I don't know how to fix it 😅 When I first formatted it, I made four FAT16 partitions, and I could write on them on my Win10 PC, using a card reader. Later on, I don't how I did, but I made the card read-only. After …

What speed are utilities like checkit, norton sysinfo, landmark speed test, ... reporting the cpu to be running at at the moment? I definitely should try some of those utilities. Maybe it's running at 16MHz despite that the BIOS sets it at 12. Considering the setup program you are using was for a …

CTRL+ALT+S doesn't work? It doesn't, for no reason. OK there's something weird going on here, the 3xxx series can access the BIOS even by pressing DEL at the startup, you don't need a setup disk for it and that's the reason you cannot find any mention of one anywhere. Have you checked the PC inside …

So it's not not a PC3286 as you wrote in your initial post which does have a 16MHz CPU, but a PC 2 286 as the BIOS says with a 12MHz CPU :D It's a PC3286, but it seems I'm not using the proper SETUP 😅 https://drive.google.com/file/d/1MtwdO9q8av7bsb-nX3HfilOCu6ueohis/view?usp=drivesdk Come on help …

This particular model was only sold as a 286/16, no other cpu options were available. So oscillators should be the right ones for 16MHz. The strange thing is that OP cannot set the speed to 16MHz in BIOS, but I'm not familiar with its BIOS screens. Perhaps some photos could help. https://drive. …

The CPU does not have a multiplier. It runs at whatever frequency the board runs it at. If you can not set a higher speed on the board your best bet is overclocking by changing out whatever generates the clock (most often an oscillator can).
