After thinking about this for a while I remembered something that makes this a while lot easier. Windows XP can use a CD as a bootdisk. Info on how to do this can be found here:
Itís a pretty easy process; all you need is some CD burning software. It might be a bit tricky to do this without a floppy drive but if you can make a BeeOS bootdisk on another computer you can either copy the needed files to your notebook or make the boot CD on it. Then all you need to do is use your CD burning software to make an image of those files and burn that image as a bootable CD.
If anyone is interested in doing this I could probably write up a short walkthrough using a freeware or shareware CD burning program.
I would also be happy to make and host an image file that you could download and use to burn a boot CD without having to mess around with the BeeOS files.
Of course all this depends on having access to a CD burner.
