OK, good to hear. And yes, you're welcome 😁 For w98 installation there is now this Wiki page, so you don't have to hunt down this information from past threads.

@Ozzuneoj: What's an OCI? Did you mean OCR? Sorry, I've been doing a lot of research over at "Bob is the Oil Guy" and mixed up a letter. Strangely enough, I have a Korean car and my OCI (oil change interval) for it is something I've been thinking about as well. :lol: Makes perfect sense lol I did …
Re: SSH2DOS - Updated for 2021 standards

Thanks, that's pretty much what I suspected. You're right it's more of a convenience to provide connectivity to modern machines, not really for security. Hopefully the potential users are aware of that. Anyways, nice to see that even the humble ole DOS hasn't been left behind 😁

Tervehdys Antti 😁 I'm not a DOS user but got curious: What are these DOS versions using as an entropy source? There is no /dev/random for DOS is there? I know in some other systems there are separate entropy daemons used, and they need to be configured by the user.

OK so the error message is clear enough: The linker can't find where these Hook* thingies reside. That usually means that some dev library is missing, or paths need to be added/fixed. But in this case I couldn't find such things referenced in the source files. If you do some grepping (e.g. in the …

@OSH: That sounds like you're missing some mingw-w64 bits (assuming you're doing this on Linux). It seems windows.h is in package mingw-w64-i686-dev, but you may need something else too. The original recipe that I used back in December (whew, time flies!) still applies. One thing to note is that the …

ALEKS, you're right to tread carefully there. Just because something is "old" doesn't mean it's suddenly free to do anything with. It probably comes down to whether this stuff has any relevance to AMD's current business. I suspect it doesn't, but it's not always so obvious. For example, Intel had …

Google Translate can also accept PDF, but it needs to be in a text form I think. And also they have some limits on how much can be translated at a time. Unless I missed something this one only has images. So it must be processed with something like Tesseract first. @Ozzuneoj: What's an OCI? Did you …

Hi OSH! This is a known issue. The solution is to use bash to run the sign_commit script, see here: https://github.com/kjliew/qemu-3dfx/issues/14

Of course there's still the matter of if the copyright still counts. Tseng Labs (according to Wikipedia) . They went on to be eventually owned (after multiple takeovers) by a pharmaceutical company (OSI Pharmaceuticals)? Don't know if it would matter what happens to such an old ROM to them (nothing …

Hmmmm... Looking at VDIAG.EXE inside a hex editor looks interesting... I see all kinds of string in there (even EGA/VGA support apparently, with as low as 16KB VRAM installed?). I also see what looks like C runtime libraries in there(stdlib etc.) with even main.c in a string... Perhaps a C …

They've come a long way for sure. To me it's impressive that it's working at all :D The performance does feel "good enough" already when compared to host, too bad it's limited to Linux for the moment. EDIT: Added the Wine version. I did try to limit customizing to a minimum here, to make it easier …

Nice idea! I rarely do any benchmarking, but at least this provided me with just enough motivation to sort out some problems I had with virgl :D There are many combinations that could be used, but it seems qemu is the one I most often reach for as the primary choice... So here's the results for my …

Hi, I did some further testing on that "Linux x64/sse4.1 black screen bug" I mentioned earlier and found out that this bug is glibc-related: UniPCemu works just fine on the musl-based Void Linux, for example. Here's a workaround for glibc-based distros (needs glibc >= 2.26 I think). Add this env …
Re: Getting UniPCemu up and running

EDIT: I managed to reproduce the problem in qemu by running it on a non-working host and using "-cpu host". So UniPCemu or some component doesn't like AMD FX or old Xeons? It doesn't seem to be related to number of threads or cores (tested with only one core, and the problem shows itself if -cpu …

Seriously cool project. You, sir, are an enthusiast! That goes for your other projects as well...I can't imagine the amount of perspiration that went in to making that stuff. I guess for ISA this is just about the best thing that still makes sense? Or do you have some other ideas waiting in the …

Interesting! Thx for the explanation. It's some kind of bug *somewhere*, but the hunt is still on... The CPU speed indicator (and the startup yellow text, and the configuration menus) do all work. They are visible in the screenshot (in that previous post). The reason why it seems hw related to me is …
Re: Getting UniPCemu up and running

Sounds good :D My "64-bit black screen problem" can be considered solved. I just tried building UniPCemu on a different host and it works there just fine. So I'll have to do some comparison to see what that was about. Could be hw related (Intel vs. AMD etc.), but we'll see. I'll report back here, if …

OK, so it's using SDL2 (as expected). I don't know what that hang is about (the switch from SDL1 to SDL2 fixed it for me - also could've been something else entirely). EDIT: I tried using valgrind (to get some nice kcachegrind process diagrams out) but closing the window kills the whole shebang …
