Not sure it qualifies as purely retro, but I putzed around Windows 98 and its included DOS 7.1 in a KVM powered QEMU VM.

I actually got PCI passthrough to work, to a point, in pure DOS on a Voodoo 3, but there are still lots of unresolved issues.

The main trick (for me at least) to actually get video output in DOS and Windows 98 GUI, is to force a VGA re-initialization right after the virtual POST . I adapted this [1] into a onliner that I added to autoexec.bat and I was greeted by working video output. Presumably Seabios does not init a passed through PCI VGA card for some reason (I am setting X-VGA to true for the Voodoo 3's hostdev and had tries fruitlessly specifying the path to a VGA ROM dump in the BAR definition). A Promise Ultra133's normall

Unfortunately it is very slow in Doom (maybe 10FPS or less) and I lose Keyboard and mouse once Doom launches .

The slowness might be due to PCIE/PCI issues.

The keyboard and mouse issues might be something
fixable through various possie means

Industrial time!
FS-97A CPU Board & PCI-7S base board (2xPICMG 1.0 ISA+PCI, 4 PCI, 2ISA slots)
Socket 479 Celeron/Pentium M board (with overclocking on industrial mobo!)
Love those bright red voltage indicators 😀
Another milestone completed - PentiumM for desktop with fully working ISA via ICH4/ITE 8888F

Which resolution are you trying to play? Voodoo 3 should be plenty for Q3 unless you are trying to drive a higher resolution.

I tried at both 800 x 640 and 1024 x 768

If you use the later patches, you might not want them. 3dfx optimizations were dropped around version 1.16 IIRC.

This board serves me very well, today I gave it a good wash so I can put it back in her box.

Hah, yep, I know how that is. Looks nice!

Installed Office 97 on my most recent project. The installation has some attitude issues when it comes to multi display setup...

Office works quite nice though.

I'm trying to keep all software and hardware around the very first Pentium II period . The plan is a really powerful workstation running Windows NT4.

More about the hardware later 😀

I finally bought and install L2 cache in my Tulip TC40 machine and it is working. Now I have to read about modding this board to use 3,3V processors.

Are you sure the board needs a modification?
It might do 3,3V CPUs when you set the jumpers accordingly.
A regular DX4 is 3,3V only. I also observed a voltage regulator near the P8-P9 connectors, so maybe...

Re: Single board computer 386-sx40 skipping VGA BIOS?

This sounds pretty neat, but I don't know enough about what you're doing to understand what you're talking about. Are you using a VM to control retro HW?

Photo 2 - board with voltage regulator, photo 3 - without voltage regulator. Interesting which voltage regulator should I use? I also see some more surface mounted elements which does not exist on my board so it will not be so easy.

Messing with some socket 478 boards. Trying to find one that will run a Willamette core but having troubles for the P4 Willamette Core: Aiming for the Stars topic...
The one ECS 848P-A V.2 has a bios that did support it according to website archive but mine has a later bios which does not.
Maybe the Gigabyte GA_8iPE1000-G will as per it's CPU support but hate to tear down something that is already working well.....
FWIW I need to post the 848P-A manuals and bios that I have as they are not on TRW or many other places.....

Two more cards saved from e-waste, cleaned and tested with new coolers.
* Gainward GeForce3 Ti 200 GS 128MB

* Asus X850XT PE AGP

I may refurbish old cooler later (smoker's household unfortunately). Memory chips were so impregnated with "oil" from old thermal pads that zalman porcupines would not stick. Also needs one 10uF 25V SMD capacitor, but works as it is. Zalman vs stock cooler is like ~30°C difference.

NFS5 crashes by hanging at the splash screen

Downgrade to a more compatible forceware version (not newer than 61.76), install official 3.5 patch.

I've since sold the board but I'll probably try it on a Chaintech CT-9BJA0, since it's also 845 SDR.

I think I had tried 45.23 first (or something lower than 71 for sure) and while NFS worked, I had choppy quality on FR2.

Lately I was experiencing a lot of weird behavior from hardware, like HDDs failing to spin up occasionally, graphics cards with trembling text, motherboards showing no video on power on... Last night it was narrowed down to the (knowingly) super cheap and expendable PSU I was using for bench testing, although it delivers correct voltages even under load. Thankfully before throwing away perfectly working hardware.

I'm no PSU expert, but after opening it up it looks like it's not worth bothering, correct?

That goes straight into the compactor. Nothing in there is worth salvaging.

Unless you have a better PSU that has a rusty case and can be fit inside this one's casing, but I wouldn't bother personally.

Ah thanks, so in the bin it goes with no remorse. It looked like being very-very bad to me too, but I needed a confirmation as I don't really know how to judge PSUs.

I upgraded my NAS op system from ubuntu 18.04 to 20.04 LTS. Result: My Win98SE box could not connect to my read only transfer share for v1SMB retro boxes.
It looks like distros are killing v1 protocol from default configurations.

So adding this section did the trick for me:

1    client min protocol = NT1
2    server min protocol = NT1
3    ntlm auth = yes
4    lanman auth = yes

I had a similar problem after the update to windows 10.
I could not find my Thecus NAS (and my retro PCs) anymore.
Win10(11) disables SMB1.0 by default
After enabling SMB in Win10 it worked again.

I'd love to see more about this build! Have you written it up anywhere?

Looks like a Silverstone type slim ITX case, but with some very different risers!
