the DVD that the M40 came with is an IMAGE of the HD that is shipped with the notebook. There is nothing but one big image file on the DVD that shipped with the M40....no files.
what you can do is load xp pro.... then download and installed EACH driver individually from the Toshiba.com website. Each driver is ready to go.
I would actually download each one...burn it to CD/DVD then start with xp pro.
