Does the term VMWare ring a bell?

I have an old student copy of VMWare Workstation on my home machine.  It's nice for running the odd Windows app that just won't work under WINE.  Only nag I have about it is the lack of real disk support.  (ie. I want to install Windows into a seperate disk not a hard file.)  Although it appears you can do this, nothing ever gets written to the disk, it all goes into a temporary hard file.  Odd...

You can run as many virtual machines as your system can handle.  For instance, my AMD XP 1800+ can run a single WinXP virtual machine on top of the native Linux without stuffing it up.  If I tried to run more I would quickly run out of memory.
