Sony's PlayStation 3 will be capable of running Mac's Tiger and the Linux operating systems, but it would seem that we won't have to wait that long to see an operating system on one of Sony's latest and greatest. After doing some testing the website PSP Update, here has proven that the PlayStation Portable will run operating systems such as Windows, FreeDOS, Linux, DLX Linux, NetBSD, OpenBSD, PicoBSD, Pragma Linux, Debian 3.0r0 and 2.2r5, and any other disk images with pre-installed systems on them.
What would you want with Linux on your PSP? We have no doubt creative answers will be handed to us in the form of working systems shortly. µ
