Recently I've been struggling with setting up any Linux distribution under VirtualPC 2007. I needed to test a Firefox plug-in under Linux and didn't have a physical Linux machine.

I've tried several distribution and the problem was always with graphics - I didn't get the system working in graphical mode. As I found out the problem was in a colour depth - it should be 16bit.

I finally succeeded with PCLinuxOS 2007.
