Re: Windows NT Versions BSoD on PCem

Great! Can you run the (crashing) emulator through GDB and perform the steps I mentioned in my previous post? You will probably need to disassemble around 100 bytes before and after the crash address.

Re: Windows NT Versions BSoD on PCem

When you say PCem crashes, does it actually crash or just exit? If the former, could you do a debug build, run GDB on it and disassemble around the crash address (which will probably be in generated code) and post it here (and also the current values of cs and pc)? If the latter, could you post pclo...

Re: Windows NT Versions BSoD on PCem

Is RTM the final released Windows 2000 or is it some kind of beta? If the latter then I'm not going to spend too much time on it.

As I said though, Windows 2000 works okay for me, with pretty much the same configuration you're both using.

Well no, that's the very definition of a soft reboot. There are some bugs I'm aware of with the IDE emulation.

Re: MMU translate from recompiler

Your comments refer to registers that don't exist on x86-32. It's also best to not be running code in a mode it wasn't designed for, regardless of how much it might appear to work; it may stop working in the future. My intention, once the 32-bit recompiler has matured a bit, is to have a seperate 64...

Re: MMU translate from recompiler

I should also say that as I'm actively working on this area of the emulator, you are quite likely to end up duplicating work I'm already doing. By all means continue - if nothing else it will be a learning experience - but be aware that I'm unlikely to accept patches for work I'm already doing / hav...

Re: Unable to build a working PCem executable on Windows 8.1

Umm, pretty sure you can use 32-bit compiler and applications on 64-bit Windows...

Besides, if you're running only 64-bit stuff then you can't use the recompiler, as that's currently 32-bit only.

Which order are you linking ALut and OpenAL in? On GCC ALut has to be before OpenAL on the command line.

Haven't seen that before. Unless by 'slower CPUs' you mean the XT-class models, which generally don't have real time clocks.

Win32s always runs with the MMU on, the GDT is above the 2GB mark. RAM size is irrelevant.

Yeah, PCem isn't going to work without a keyboard and mouse, and it probably wouldn't be very useful with just touchscreen input anyway.

trap is set at the beginning of all interpreted instructions, in exec386().

I like how little faith you have in my abilities to actually test what I'm committing.
