Yes, an Eee PC can run 10 operating systems in parallel!
I installed qemu 0.11.1 with kqemu 1.4.0 on my Eee PC 900 (1Ghz/1GB running Linux), using an external hard-disk for storage. I was able to get the following operating systems running with very little difficulty:
OpenBSD NetBSD FreeBSD DragonFlyBSD Debian GNU/Linux Windows XP Mac OS X Haiku
I am able to provide a torrent containing all of the free OS images, with the shell scripts I wrote. This may be useful to other people who would like to test the portability of their programs.
Please read the full story here if you’re also interested in qemu.
