Maybe the XP disk has the drivers you need on the disk but Vista doesn't. Did you get any drivers on a floppy with the mobo?
No floppy drivers came in the box. In fact, I don't even have my floppy drive installed anymore. Do you know how to use a USB drive to emulate a floppy drive so that if I stick it in and boot from it, it will say A:\ in DOS mode?
As for the stability and speed of Vista that was installed over a fresh copy of XP, I don't perceive any difference with a clean installed Vista which is a good thing.
