Bochs

Most IT people know about VMWare, an environment that lets you run another operating system on your PC. VMWare will allow you to run eg Win 98 and associated software on your Unix/X11 workstation, displaying a window on your workstation, simulating a monitor on a PC. It's kinda strange seeing bootmessages appear in a window. But VMWare is pricy; you can use a VMWare copy for about a month with a temporary license, but after that, you are considered to pay for it.

Bochs is an open source implementation of VMWare. I was surprised about the maturity of the project. It's still not that advanced as VMWare, or as userfriendly, but if you have a minimum of geek capabilities, you can run an OS in it. I had to fiddle a bit with the virtual disk parameters, but finally got it working, and at this very moment, I'm installing FreeBSD in a Bochs cage.
