Major project: install WinXP and Debian Linux on my IBM Thinkpad T30 laptop

My next major Linux install will be to get this Thinkpad T30 working as a dual boot machine. I will download and install Debian as well as WinXP on this laptop. I still need to research the Debian step. I also need to do back up with the 20GB USB drive but the My Documents folder on my Thinkpad is only some 6 GB in size so this USB 20GB drive will do this no problem. I must remember to do a Win Fat format on this USB drive with my eMac computer.
