I am unable to restore operating system after installing mother board from salvaged pc on a Presario 6440 with Titan II motherboard Pentium II 266 mhz. When I run the Compaq quick restore after I enter the serial# and model # it attempts to read the restore CD but it just does nothing. Does it require the serial # from the PC the motherboard came from? Or is there another method to be able to load OS from the recover disk. I am able to get to the files on the recover disk but I am not sure how or what file to execute to get things rolling. Any suggestions will be greatly appreciated.
