I think somehow Hewlett Packard either wanted to make installing Windows XP hard on dv2700 series laptop's or they just wanted to see how good us geeks actually are.
Well, I think we passed.
The Drivers & Specs for the dv2742se & dv2700 series are:
Slipstreaming XP + SP2 I got working with nLite that comes with it's own boot image so you don't need IsoBuster. It'll also slipstream the SATA drivers into it, building an ISO file it'll also burn to CD.
The Bluetooth driver's were difficult, every package I could find was corrupt, but I found a post here that pointed to a new package here in the Czech Republic that worked.
