Re: Need to identify 486 motherboard and VGA/EGA graphic card

The video card seems to be made by Samsung (according to the FCC-ID : A3LGTI-VGA1) And it's a VGA card.

Hope the update goes well ! Have had some issues doing basic searches over the last few weeks and I know you are constantly trying to improve it but the basic search features seem to have some issues lately or maybe is just me. Some fields still can't give good results (such as form factor and ram …

No, because they are connected through FSB, so they will be running at 100 Mhz, if FSB is 100 mhz. Only Socket A motherboards have this feature, they could run memory higher (so with 133 mhz FSB, they could use 266 and 333 Mhz DDR1 memories), but performance gain was really very small, I would say …

Maybe a picopsu would do the trick ?

This is probably a mistake. The people who made these schemas made lots of mistakes. They probably mistook the bios chip for the tag chip (notice that there's no bios chip on this schema)

Uh19 (see my signature) would be a great place too 😀

Yes beware. Make sure nothing's easily flammable in the room too, because the things it projects could be fire hazard I think. To test thing you can simply disconnect one leg of each tantalum capacitors. The board will probably work fine without it and you'll see if a tantalum was the culprit.
Re: Best way to image disks and scan old manuals?
Posted on 2021-07-09, 15:48
For disk imaging under DOS environments I highly recommend M. Brutman's DskImage . It's a very simple utility, but it's fast, produces exact copies of the original disk and can retry reading failed sectors. I would avoid stuff such as WinImage as the image produced is not identical to the original …

Re: New solutions to the ATX -5V problem

Good work guys ! A bit off topic, but I think another kind of adapter should exist for PSUs (and that would probably require more work) : some way to adapt modern PSUs that are 12V oriented to something 5V oriented. By that I mean taking some part of the +12v rail and beefing up the +5v rail for …

Hello, we've documented this board here : http://www.win3x.org/uh19/motherboard/show/6929 Can you please dump the bios so we can add it ?
Re: Build Win98 from ZERO
Posted on 2021-07-04, 14:40
4GB-8GB of ram is way too much for windows 98. Nothing made for it will even benefit from it. As a 32-bit OS, the max it could theoritically support is 3.xGB. Now, with the way it's made, the absolute max is theoritically 2GB iirc, and in reality the max (without unofficial patches) is between 512MB …
Re: Very unique 386 motherboard “Unknown Make/Model”
Posted on 2021-07-03, 15:12
Yes, unfortunately that ID isn't documented anywhere. That doesn't mean it will never show up though. With UH19 we're planning to make an up to date manufacturer id for POST strings.
Re: Very unique 386 motherboard “Unknown Make/Model”
Posted on 2021-07-03, 13:12
Unfortunately, no it cannot do that, (I don't think any software dumping tool can do that actually). If you have a TL866 you can dump it that way, otherwise it'd still be better than nothing because it's possible to split the eprom file (now I don't know exactly how the split is made on your board, …

What bios is in there ? Phoenix ? AMI ? Mr BIOS ? Award ? If it's AMI (or maybe even award), you should have a POST string which can be used to identify it. Can you please show it to us (and/or dump your BIOS using this http://cd.textfiles.com/microhaus/mhblackbox3 … MORY/GETROM.ZIP) ?

but virtualpc and vmware are not emulators, they are virtualizers, they are almost the same thing as i install win98 directly on my core2quad, they can emulate a sound, video and network card, but they don't emulate a processor. The first version of Connectix Virtual PC for x86 host computers was …

It should be fine. Back then you could even run a BIOS from another motherboard and have a chance that it'd work just right. Just try it and the worst you might get is a black screen.
