Yup. this is my first really old PC. I never really installed Windows 98 or 95 or earlier versions with need of a floppy disk. New expierence for me 😀

So, after half a day, it seems that cable and floppy drive were damaged. Found cheap ~2001 PC for a few euros, switched FDD and cable and now it works fine 😀 Also 486 CD drive was bad too, switched for an IDE DVD.
Now, I'm trying to install Windows 95, but it just get stuck on this screen blue screen. Even before, when loading Windowss image, picture is distored (same distorted picture was with Windows 98 too).

That doesn't look good. Your video card might have a problem. I'd say it could be the "ramdac", but it could be something totally different.

Again your cd ROM drive may be perfectly fine, do you use official pressed discs or discs you burned yourself ? Old drives weren't made to read burned discs. Some of them cannot read them. Other may be able to read them if you burn your CD-ROMs slow enough.

Used a CD-R. I was getting error "CDR101 Not Ready Reading Drive E". Only fourth drive worked 🤣.

So, after few pushes of Reset, it finally finalized installation. What's best website for drivers?

So I wouldn't blame the original CD-Rom drive right away. Try to burn your next CD as slow as possible and/or pressed discs. These will probably work.

You can try vogonsdrivers.com and win3x.org.
There are probably others, but usually googling around works for me.
What drivers do you need ?

UM8810PAIO motherboard, S3 Virge/DX graphics card and an internet card?

I think something went wrong with your windows installation because according to this you have 3 parallel ports and 6 serial ports. Try to delete all parallel and serial ports from this menu and launch "add new hardware" from the control panel and let windows detect new hardware.

Your motherboard should be fully supported by windows 95

What's your ethernet card ?

The drivers you need for the S3 card should be here http://www.win3x.org/win3board/viewtopic.php? … le=30&f=8&t=289

How do I install Winrar or Winzip?

That is weird, though personally I'm using 7zip (if you want to give it a shot you'll have to install Internet Explorer 4 to have it working)
Where did you get these ?

So, after countless of hours. Still cannot get to install any Winzip, Winrar, 7zip... I even reinstalled Windows, this time without any issues, no freezes. Installed Windows 95 OSR 2.5, maybe wrong version?

This version is too new use version 9.20 exe (not msi) and 32 bit.
I forgot it mention that I'm sorry 🙁

Windows 95 osr 2.5 should come with ie4 on the cd. You'll have to install it to get 7zip to work.

Thanks, I managed to install 9.2. BUT, still cannot extract any archives... WTF?! My last steps would be install GPU drivers and try Doom game.

You just want some old school carnage.
Me approves! 😀

Yea, so on lowest resolutions it's artifacting. On 640x480 it runs fine, but like 15 FPS 😁

Also, backup of BIOS.

Final assembly 😀
Added motheboard and ECS VRM photos.
Thank you all for the help!

Top !!!
Thank you very much.

The vrm photos are better than what I had before. Now it may be possible to retro engineer it, but if you could make a second photo and pull the regulator's cooler I think this will reveal the very last things that we'd need to replicate one.
