You Windows Mobile Pocket PC is desgined to run on Microsoft Windows Mobile operating system.
Windows XP cannot be run on ARM processors like the one you have on your Pocket PC (Intel PXA 270 aka Intel Bullverde).
However, you can can upgrade your Pocket PC from Windows Mobile 5 (that is provided by default) to Windows Mobile 6 (I did that myself on my own i-mate JasJar). To do this upgrade, you need to get some unofficial ROMs (the ones that are not built by the manufacturers, but by some developers who create their own ROMs according to requirements.) Sometimes, this cannot be safe, however, I have used one ROM for i-mate JasJar that upgraded it to Windows Mobile 6.0 making it better except for the problems as mentioned below:
- The RAM is now more eaten up, so you have to sometimes restart your device to use camera as the camera is a RAM intensive application and you device sometimes does not have that amount of RAM vacant
- Video calls are now no more supported
- Internet Telephony cannot be used
So, if you can sacrifice with these three flaws, you can upgrade to Windows Mobile 6 using this custom ROM:
Finally, as you now know that you cannot actually have Windows XP in your Pocket PC, there is an application that however, lets you have the look and feel of Windows XP on your Pocket PC. The earlier versions of this application were free, but the versions 4.0 onwards are now paid ($1 per user license). It is named 'XP Modification for Pocket PCs'. You can get it from the internet or from the vendor itself http://www.teamfluxion.com
