![]() ![]() It greatly improves OS development because the virtual machine restarts much quicker than real hardware, plus it offers detailed debugging functionality that can help greatly during kernel development. Bochs has already searched for a configuration file (typically called bochsrc.txt) and loaded it if it could be found. This was 3-4 years ago mind you, a lot can happen in that time), perhaps they have what you need although I haven't really kept up on them so perhaps someone else here can point you in the right direction. Bochs is a steadily improving emulator for the x86 platform. MAKEgmake PKGCONFIGpkgconf XDGDATAHOME/construction/emulators/bochs. I'm aware of several freeware emulators (Bochs being one, although last time I tried that it was as slow as a wet week, only emulated a 386 and I never succeeded in installing Win95 under it. gameport support GDBSTUBoff: GDB stub support IDLEHACKoff: Keep Bochs. And write this to a floppy image like this: (Assuming a Unix-type system.) dd if/dev/zero offloppy.img bs512 count2880 dd iffoo offloppy.img convnotrunc. With the gui debugger open, you can at any time press the 'break' button and in the View menu, you have the 'Physical MemDump' and 'Linear MemDump' options, just enter the start address and bochs will dump 4kB for you. Then you can assemble with: nasm foo.asm. Given that neither VMWare or Virtual PC are really designed to play games (Virtual PC in particular started out as a way for Mac users to run PC software which is why I'm guessing it's emulation is so much better than VMWare.) I doubt they would have thought to include proper gameport emulation.Īs the need to run DOS software under NT OS's becomes more necessary (which it will eventually since people won't be able to avoid moving away from 9x forever, gamers especially will be stung hard by Microsofts cessation of support for 9x when DirectX no longer comes in a 9x flavour) they'll think to add it but I don't see that happening any time soon. when you will build it, and add this option in your Bochs configuration file: displaylibrary: x, options 'guidebug'.
