Funny, I was just having this issue a few hours ago after reassembling my 386 (Asus ISA-386C, AMI BIOS). In my case, I have two floppies on the cable (3.5 & 5.25), and the BIOS had only autodetected the 5.25. Yet, it would seek the 3.5 on boot and would even read a 3.5 disk, before stalling at the …

Job done. I went with electrolytics (2x 16V and 2x 25V) and these were the wrong approach for one reason: They don't quite fit in that little space! So they're kind of sticking out at different heights and angles, looking like the Big Book of British Smiles. I will not be providing a photo. But I'm …

I guess you could make the argument that an exploding tantalum is a good indication that you have a problem, as opposed to a sneaky slow leak 😁 But either way it's probably a decade or so before you have to worry. Still on the fence about which way I'll go.

My board has a couple of blown tantalums right alongside the AT connector: PXL_20210912_051913063.jpg Full pic of board in better days: IMG_20200504_154621.jpg I aim to replace the whole row. I'll be able to read values off the good two once they're out, but obviously not the other two. I see that …

Great work tracking this down and sharing it along with the story! From the video I didn't realise it was interactive. Runs fine in Win11, and I just spent too long trying to land hits on those orbs. This really should go up on archive.org.

It's not the same card, but I had similar trouble with one of those new eBay Rage cards in a 98 box. No installer (exe) would recognise it. In the end I got it going by letting 98 install the standard VGA driver, then updating the driver from Device Manager - pointing it to an inf in the Pro driver …

Very interesting post from a similar thread. I think I'll start by replacing the keyboard controller. Yep, at least one of the OPs faults is centered around the fact that the chipset isn't able to control the A20 line. The A20 line does indeed get controlled by the keyboard controller in 286 based …

Yes it's lovely that Microsoft has done all this work on APIs and UWP apps, but none of that helps people who just want to change their MIDI device. At the end of the day we're out here using third party programs to replace a feature they removed.
