Yep, that's pretty much like the Matrox M3D I had back in the day. I actually ended up placing a heat sink on the main chip on that card. I remember using some kind of silicone glue to fix the heat sink on the card, because there were no mounting holes on it. (I know, not very elegant. I'm sure …

Just thought that SBEMU now entails the need for a usb mouse driver for DOS :) Making a slight off-topic detour in this response: Some BIOSes might already automatically emulate a PS/2 mouse when a USB mouse is plugged in, the same way as how they emulate a PS/2 keyboard in legacy BIOS mode when a …

I think JUDAS might be an alternative. But first I think I'd contact the author of MPXPlay to clarify the license. I didn't build MPXPlay at all. But I think I can contact the author to integrate my fix. BTW I just added BLASTER environment support (create one or change it). so you can forget about …

Excellent progress you continue to make, crazii! :rocket: I do have one concern, though: you are using sources from the Mpxplay project for the backend drivers. But those sources have not been released under an OSI-approved license , making the terms of use a bit unclear. These comments at the top …

Debugging DOOM in a Windows DOS box to see why it works there is not too promising. That's because the Tenberry DOS extender is aware of enhanced mode Windows and behaves differently there. If you think so then use another DOS extender like DOS32/A which as far as I remember does not have any …

Yeah. I fixed some bugs in MPXPlay too. It did have no sound in Virtualbox with HDA, it uses PIO for immediate commands while Virtualbox only support MMIO, I read the HDA spec and found the PIO are optional only. That makes a lot of sense, actually. As I understand it, MMIO is much more …

Cool, it's worth a try. But I remember reading some comments in VSB that it only works with QEMM, doesn't that means other emms is not capable, or VSB didn't bother to support other emms?

the reason to use QEMM is that, (according to some online docs) EMM386 doesn't support trapping port below 100h, which makes it unable to virtualize DMA & IRQ. I don't know about other memory managers. it'll be much appreciated if docs about other emms are provided. There may be another option: …

It has always been one of the big "THOU SHALT NOT"s of HDMI that modern HD content can't go to an analog channel, hence HDCP fails when trying to use streaming boxes etc through analog converters.

And if I understand the differences between UHCI and OHCI correctly, I would have to try get a USB 2.0 card with a …
