It's a 1GB RAM setup of a i440fx motherboard (the first one in the PCem-X hardware list in the source code). OK, should be more than enough... Have you tried to dig in the boot logs to see the exact spot where the crash happens? NetBSD seems to be less picky on hw, but on the Linux front there's a …

Anyone knows more software I can use to verify/diagnose x86 emulation(Pentium II w/o FPU)? Slackware linux 1.01's (linux 0.99pl12) boot disk and Minix 3.3.0 both crash with page faults somehow? How much memory did you have for the Linux test? I tested some minimal 32-bit Linux distros (current ones …

Sorry for the dumb question but kjliew test was made on a Linux running computer ? Maybe I'm trying the wrong way as I'm tinkering with VM on a Win10 computer. Yes the most recent tests (that use qemu-5.2.0) were made on Linux, but I think it *should* work on a Win10 host too (WHPX is a Windows …

Just be sure of polarity when installing new caps... match the polarity of the old caps, not the markings on the board. I've seen a couple devices over the years where the - line on the capacitor was clearly going into a + on the PCB, and yet it worked for 10+ years, so the markings were incorrect. …

If you're interested in the details of what the BIOS is doing, grab yourself a copy of Pinczakko's BIOS Disassembly Ninjutsu Uncovered. It has a whole section about Award 6.00PG, nicely dissected.

Vanilla qemu won't help you much, you need to compile a customized version with kjliew's qemu-3dfx, see here: https://www.vogons.org/viewtopic.php?f=24&t=60950 The current version works on a Linux host but I don't know what the situation is with mingw. I know that robertmo has successfully run …

Trying once more: What you describe sounds a lot like a corrupt BIOS. Do you have any way of flashing the EEPROM outside of the board? You have multiple PCs in your signature. Why not use one of those to perform a hot flash? ^ This. Looks like there have been at least *some* memory-related issues, …

I made a comparison of some DOS-based C compilers: https://github.com/leikareipa/dccb. The code can be compiled using a bunch of compilers, and some sample performance results are included. I'd use the Digital Mars C/C++ compiler, but the Microsoft C/C++ one is pretty good too. As far as I know, …

As they say..."it depends" Maybe you could provide some info on what kind of coding you are planning to do? Any specific hardware target perhaps? Any memory constrictions? DOS extender needed? Libraries you care about? And so on... If you care about portability to gcc, I guess DJGPP would then be a …

Generally I'm not much of gamer nowadays, but this one, I do like: Cataclysm: Dark Days Ahead Very appropriate setting, for these pandemic times. NetHack & DF veterans, go ahead check it out if you haven't already! Everyone else: Prepare for a *steep* learning curve... I think you can also play CDDA …
