Tonight I have mostly been ... Installing Windows 2000 on a Debian machine with Qemu, a processor emulator and virutalization program.
I have Windows 2000 running in a little window on my desktop. Speed isn't fantastic, but it's certainly usable.
Now I'm downloading service packs and updates, then I'll call it a night.
This will be useful for testing webpages with Internet Explorer, and generally messing about.
