Re: What's the value of a socket 423 P4 system?

I have a little collection of s423 motherboards, mostly QDI brand. Why? Because they have PC/PCI connectors on them meaning they support DOS sound even without ISA slots.

Depending on the mechanism, of it's some kind of carbon-backed switch or dome, you can repair these with a bit of special paint. 8-bit Guy did an episode on this for a different keyboard. It's not the computer keyboard. That works fine. It's the controls of the mechanism of the tape deck, you see …

It's more than a belt; several of the buttons don't work properly, either can't be pressed down or when pressed don't click in place and stay down (the "play" button does that), so there's more to it. It's not critical, I have a Interface 1bis to use with it https://sites.google.com/site/ …

It lives. 😀 Had to glue the case back together in a number of places, add a composite out mod and a PAL/NTSC converter, and also build a US-compatible power supply. The cassette player/recorder is still busted. But the "computer" part works fine.

I've also had better results with AMD-based thin clients; the best I have so far as compatibility goes is a Zotac Zbox MA760, which has a FX-7600P chip and is similar in many ways to the Wyse 5060. It's only a little older (2014). Significantly better DOS compatibility than Intel-based machines like …
Re: Newer iGPUs (past HD5xx) and VBE 2.0/3.0 modes: any hope?

Of course, because the chipsets in the 2 systems aren't compatible with the other's CPU. I was talking of the CPU generation, not the GPU generation. As in, "the xth CPU generation and its associated iGPU" How do you suggest that I debug the problem? I have tried the VBE test program from UniVBE, …

They all work without issues on the previous generation iGPUs, HD4xxx on Ivy Bridge chips.

Like we would have if the graphics circuit never switched from text mode to graphics mode? If this is the case then Dune has noticed that the mode switch failed. Otherwise Dune would start writing into the video memory and cause gibberish text to appear on the display. But if Dune was using plain …

I am not aware of any significant VGA problems in Gen6. Could you describe what you have noticed, please? This could be rather helpful for me. Thank you. Black screen with blinking cursor when attempting to run Dune, Dune2 and Duke3d on a Dell Optiplex 3050m with a i5-6600T CPU using its iGPU ( …

This came about in a discussion in sound/SBEMU and since it was off-topic there I am moving this here. https://www.vogons.org/viewtopic.php?p=1153472#p1153472 Basically, Intel CPUs with iGPUs past HD5xx/6xx have broken VGA compatibility making some older games impossible to run. In my experience, …

One more test that I did tonight. I went back to the Optiplex 3050m system and replaced the CPU: instead of the one I tried at first (i5-6600T) I installed a i5-7600T. That was the only change I made. SBEMU does not work at all anymore. It gives me: internal buffer overflow system halted. After that …

general note: the sound volume for all OPL and SB sound is very low in all instances where it works. what volume option did you use? /vol9 will be the max, have you used that? Oh I completely forgot about the volume options. :) I'll test tonight when I get back from work. FWIW the EB 8470 uses a …

Indeed it doesn't. With no SBEMU loaded, and sound disabled (otherwise it complains "can't find FM chip") indeed Duke3D ends up in that same blank screen. The same may happen with the other games that get a blank screen when launched in my tests above (Dune and Dune2) on this machine. They all work …

I tried this on several different computers before I had it work. I used the method in this video to create a flash drive with FreeDOS and SBEMU. I first tried it on my Dell Latitude E6500. SBEMU ran and recognized the sound card as Intel HDA. I got no sound in any game I tried. I tried plugging in …

Hey, the I=b000-b7ff is a very good hint. Jemmex does not detect/use that automatically. Now I can have mouse and SBEMU and EMS to play FE2, without that I had to leave out the mouse which made the game unplayable (it's a space combat simulator, no mouse=control of the ship and UI is crap). 😀
