BOCHS CMOS IMAGE FILE PORTABLE

Remember those classic arcade games from your childhood? Or perhaps you have a portable games device and are tired of carrying around both your H/PC and console? Figure 1: Console Game Emulation The most wide spread use of Emulation in the consumer market comes from the games console and legacy platform sector. If that wasn't enough, you then have to consider the other inflated system requirements such as RAM, video and storage. The overall result of this is that substantially more powerful underlying processing hardware is needed to maintain performance between all three components.

The physical processor in the computer not only has to manage it's own native operating system, but also the virtual operating system and the mapping or substitution of the architectural calls made by the virtual system.

While on the one hand you can use the software emulator to create a map between the physical system architecture and that of the virtual, this in itself is less than ideal, notably from a performance perspective. There is a trade off to be made through this. An emulated system provides an environment in which whatever is running within it is oblivious to the physical hardware and native operating system of the computer. This can be stepped up to another level called Emulation. Taking the concept of virtualisation, which separates the hardware of a computer and in simple terms allows it to be seen by more than one operating system. The idea of spreading the disparate abilities of the hardware behind this revolution has become more of a reality, and will become something everyone will invisibly benefit from in the coming years.

Over the years as accessible computing has made vast inroads into our every day lives, and inexorably the cogitative abilities of the humble home or office PC have increased. Using a method known as virtualisation back in the heady days of large symmetric mainframe systems, it was common for resources to be better optimised by taking the multiprocessor system and through virtualisation dedicating different installations of the operating systems to run against one of the available processors. The process of running an operating system literally on top of another one is not a new one.

So, is this an elaborate trick designed to fool those users of less experience? Not quite, though users of less experienced disposition may wish to turn away now and be happy in their naivety. An operating system designed for a specific CPU architecture say the x86 architecture on your desktop PC, simply could not contemplate running under another processor type (for instance the XScale on your Handheld PC).

Just as with how a H/PC user will appreciate that a MIPS application cannot run on a StrongARM backed device, and a Windows CE application cannot run on your Windows or Linux desktop PC. The art of running any operating system is one that requires a fundamental understanding of the makeup of the hardware it will run on. Windows 98 was actually running on the Axim in front of Windows Mobile. The PPC wasn't using a network connection there was nothing out of the ordinary in the hardware makeup of the PPC itself - just a run of the mill Windows Mobile 2003 device. Here though this wasn't an experiment in remote connectivity, this was a far more highbrow exercise.

Anyone with a network connection and a VNC client can achieve that in a relatively short space of time. Nothing spectacular in that one would think. Of particular note in this category are the exploits of a number of overly excited Axim (Dell PPC) users who have been swapping images of the Windows 98 desktop in their QVGA and VGA displays since the middle of last year. When you have a critical mass of active developers confined to a small, 240x340 space inevitably someone will push the boat out from harbour and sail it right over a waterfall surfacing in the realm of what most people would call abject fantasy. The Pocket PC (PPC) I will admit - through circumstance and not for any prevailing feature of its own - does have one advantage. BOCHS 2.1.1 - x86 Emulation makes it to the H/PC
