Unboxed the DataExpert OPTI-495SX rev 1.1 board (386DX-40 integrated). It needs a lot of TLC, patching, trace repairs, and a lot of other items to make it look clean and efficient. Here's a picture of the board: IMG_20211015_173057408~2.jpg I'd work on it tonight, but after work, I have to go to …

I'd be interested in benchmarks and your experience with it. I soldered a realtek LAN chip on a m/b, as the old one died. I lifted 2 traces as it wouldn't come off. Still no luck, not working. And it's full of components around 🙁 Maybe I should check V and other values.

Lm80 replaced and board is like new. No, soldering is not better than factory but I'm satisfied. - THE END -

I can't believe this, tried and retried a cap blew clean. Replaced and now works again. I always loved Stephen King for his fantasy but this is getting close to possession to mock me 😀 I just need to have a neighbour called Eugene and I'm done.

Took it out of storage, soldered the new LM80 and doesn't turn on. No shorts on chip. No dead shorts on motherboard. Have no idea. All components work and retried in other system. I hate this board.

I soldered the LM80 chips I got and the board refuses to turn on at all. Tomorrow I'll desolder this chip and see if it is a bad chip (I ordered 2) or fakes. Tired and no conclusion. Going to bed and sleep it off 😀

Your cpu: https://www.cpu-world.com/sspec/SL/SL6C7.html Core voltage is 1.5V Setting it to "manual" and put cpu multi to 13 and frequency to 100? Result? Underclocking shouldn't be an issue, could be, as suggested, a BIOS issue. Try reflashing if last version or upgrade if not. Edit, could you …

Did 3 wrappings and it works. I had to glue it as it would otherwise come off and give a hardware error. I used some epoxy and have to wait until tomorrow when it's cured. It needs a very grippy ring, mine is 2mm. Cartridge has issues. Might need to buy a new one. Does anyone have a pic of the …

Can you please post the BIOS string here The entire bios was dumped and uploaded on page 1 of this thread Bruno.. Maybe you could rewrite the first part of post n.1 and add all the files to have all the relevant data/files at the beginning, avoiding to go read all the posts. After this bad sentence …

Cleaned and old IBM Thinkpad T22 (P III 900mhz Coppermine in micro-pga)) - in bad shape with issue with the LCD. Bought for 5€ just to test cpus as the socket is easily accessible. Then comes a PAckard Bell with a Duron 1200mhz - in medium shape; previous owner put a normal fan to replace the dead …

If you have the old jumper settings for the dx-100 that's a nice overclock for that chip 😀 I mean that it's too much high and fails. Looks like a too far OC.

Checked two cd-rom drives. The first needed some oil and grease; now works but with front bezel it doesn't get the all the way in or has issues ejecting the tray. Second cannot read data nor audio cds; I can only assume it's good for parts.

Do you have another cpu, dx/2, to test? Maybe the bus is too fast and corrupting the floppiy"s data transmission? Maybe data isn't with correct divider in bios. Try tinkering with bus/2 /4 /8 ... or similar

Is copying files from the floppy drive on this motherboard as quick as on another one? I'm wondering if maybe once it's booted DOS allows for more retries before failing than the boot loader. I know I had a failing floppy drive where it would still work, but copying files from it was slow as it'd …
