Compatibility still isn't complete enough to get working with Windows 9x. So far all development is concentrated on DOS support, not much effort has been spent on anything else so far.

I suppose you truly won't know unless you try. One thing that turns a lot of people off of 3d printed parts is the appearance. If you have the capability to do resin prints, that would be a big advantage. Even though resin parts are probably weaker. I could see a demand for IO shields to mount AT …

I'm not sure what the deal is either. So far I have never had a problem with DirectX 9 breaking an install of Windows98SE. I've never heard of it before until recently.

This is what I was hoping for. Either a real SCSI controller, or perhaps a CPLD or FPGA to drive the SCSI bus. Not a micro controller trying to emulate a controller over their gpio interface.

So, if I understand correctly this project is essentially a SBC with a SCSI interface in target mode? So similar in idea to PiSCSI, except hopefully far faster than the RasberryPI gpio interface. It would make sense to use FreeBSD, since it was one of the only open source operating systems that …

I finally happened to get a chance to try out the PicoGUS I recently bought from Joe's Computer Museum. I am using it in my recently acquired 486DX-33 system with a MS-4132G motherboard. At first I was having problems with system crashes that I was not experiencing with a Sound Blaster 2.0. I was …

Cool project, I have been looking into building something like this for my 486 system. This way i can hook it up to my KVM. There is also this project that adapts serial to USB. USB to Serial Mouse using the Pi Pico!

I believe the Z230 SFF is Haswell, that won't have chip set drivers for XP. The similar Z220 SFF series is is Ivy Bridge, and it has XP drivers on the HP support page.

Almost certainly a false positive from your antivirus. It is becoming an increasingly common problem for old software to get flagged as a virus. Especially software that directly accesses hardware, or uses programming tricks like self modifying code. In this case it looks like Kaspersky doesn't like …

Norton Ghost was definitely the go to tool back in the day for resizing and copying drives and partitions. If you are comfortable with Linux, Gparted is a decent option as well.

If you could get away with a small form factor system under your monitor, that would make for an awesome WinXP machine. The HP Z220 SFF is a good example.

Glad I was able to help explain at least some of what is going on. 388h end up becoming somewhat the de-facto standard for Sound Blaster FM and Adlib, unfortunately that meant it became hard-coded into a lot of DOS software.

What happens if I have no PCI card but several ISA cards. Which will be chosen? All? How do you set up several cards under these conditions? The simple answer is don't do that. The problem is resource conflicts. Unless you reassign the resources of one of the cards, neither will work correctly. How …
