Commercial PC emulators (VMware, Connectix, etc.) canħ2 achieve much high emulation speed using a technique calledħ5 Virtualization takes advantage of simulating x86 instructions on anħ6 x86 machine, allowing large portions of the simulation to take placeħ7 at native hardware speed.
To model theĦ9 processor accurately, Bochs must run many instructions for every simulated x86ħ0 instruction, and this makes the simulated machine many times slower thanħ1 the physical machine. However,Ħ8 the downside of Bochs' approach is simulation performance.

In other words, itĦ3 does not depend on the native instructions of the host machine at all.Ħ4 This is both a strength and a weakness, and it's the major difference betweenĦ5 Bochs and many other x86 emulation software such as VirtualBox, VMware, etc.Ħ6 Because Bochs uses software simulation for every single x86 instruction, itĦ7 can simulate a Windows application on an Alpha or Sun workstation. No matter what theĦ2 host platform is, Bochs still simulates x86 hardware. The guest platform is the operatingĥ9 system and applications that Bochs is simulating.Ħ1, including x86, PPC, Alpha, Sun, and MIPS.
The host platform isĥ8 the machine that runs the Bochs software. This approach allows BochsĤ7 to run a wide variety of software with no modification, include most popularĤ8 x86 operating systems: Windows 95/98/NT/2000/XP and Vista, all Linux flavors,ĥ3 Bochs is written in the C++ programming language, and is designed to runĥ6 Since Bochs can run on one kind of machine and simulate another machine, weĥ7 have to be clear in our terminology to avoid confusion.
Because BochsĤ5 simulates the whole PC environment, the software running in the simulationĤ6 "believes" it is running on a real machine. Bochs can be compiled to emulate many differentģ9 x86 CPUs, from early 386 to the most recent x86-64 Intel and AMDĤ0 processors which may even not reached the market yet.Ĥ1 42 Bochs interprets every instruction from power-up to reboot, and hasĤ3 device models for all of the standard PC peripherals: keyboard, mouse,Ĥ4 VGA card/monitor, disks, timer chips, network card, etc.

I found this out while messing around with a softmodded Nintendo Wii and running DosBox on a Wii is really slow, and that's because the processor needs to be emulated on a PowerPC CPU, and that goes for all the permutations like setting it to 386 mode or 486 or pentium mode.Īlso while I'm on the Topic of the Nintendo Wii, there's a BOCHS for it too (at least as far as I'm concerned) (or was it QEMU? correct me if i'm wrong), so theoretically, you could do a slight permutation of this guide and make into "Run Windows XP on Wii" or something like that, as it wouldn't take too much effort.As a special service "Fossies" has tried to format the requested text file into HTML format (style: standard) with prefixed line numbers.Īlternatively you can here view or download the uninterpreted source code file.Ī hint: This file contains one or more very long lines, so maybe it is better readable using the pure text view mode that shows the contents as wrapped lines within the browser window.ģ6 Bochs is a program that simulates a complete Intel x86 computer.ģ7 It includes emulation of the Intel x86 CPU, common I/O devices,ģ8 and a custom BIOS. Please note, I've seen android devices with x86 processors in them, and that would work a lot better as then the software doesn't even need to emulate the x86 architecture. OK, BIG WALL OF TEXT INBOUND! sorry in advance. Since this can be dome for windows XP, can you possibly follow the same steps and get windows 2000 or possibly 95 on Android?Īnd if so, can going old school make the preformance increase and have it be not as slow?
