didn't try just booting into it ?
not sure if a hardware independent restore (to get the drive functioning on different hardware) would probably drop network drivers and therefore any network settings that were saved...
try and get lucky booting the drive off a similarly aged mainboard
You need to get access to the registry. XP they are stored in "C:\%windir%\System32\Config" or something. Not sure what tool you need to load those files up to get access to them being a security issue and all ;)
