Hmm...I assume it does not detect the right capacity? Maybe your drive tries to access 1.2 MB but its a 360K or 180K disk? Do you have a 360k disk drive?

I would try to create a disk image with your favorite utility and note what sectors on the floppy are actually unreadable. Post that image if its not too bad...maybe we are able to reconstruct this file 😉

Nice board! I would also recommend to try some other floppy drives, had success with many old floppies that failed to be read in one. What is the exact size of the file? Is there any hint in the manual how to enable this feature by Software?

Enough for today :dead: Installed a new CPU socket and inserted a CPU. Soldered the 2 caps and attached wires where I intended to connect the ISA bus to. I was thinking that the board should power on without the 12 V lines connected and I tried it. As expected, the +12V / -12V lights on the card did …

Nice! Yours had a faster CPU but it looks very similar. Let me know if you need detail pics or something else. Hedeka...I knew this from somewhere... It the same brand I got an interesting ISA VGA 2 weeks ago from. It has a TV-out and works at least in my 80286, but not in my K6-2. Never seen this …

Hi Frog86, also from my side welcome to the forum and many thanks for your detailed and very useful reply! I already cleaned the board with vinegar and let it react for about 1h. Afterwards I cleaned with water, then grain alcohol and dried with a hair dryer. The result you can see on the photo. …

You should first remove that battery ;-) Post a picture of the whole board, I think there is good chance to find some documentation on the usual sites... The front display has nothing to say as it is not connected to the settings on the board. To hear the beep codes is a sign that the CPU is running …

What would be the reason of buying a motherboard without any chips in the sockets? CPUs and keyboard chips aren't hard to find, but bios chips.... and (I guess) pay more then $10 for it :confused: The BIOS is no issue at all, I have already 2 very similar boards, see here https://www.vogons.org/ …
