1. XP SP2 will have SP2 integrated. Your's may/may not have SP2. You can check your version - see click here
2. No to the original & slipstreamed versions, because...
3. The SATA drivers are unique to the SATA on your motherboard (there are no Microsoft generic SATA drivers that I know of). So you'll need to visit your motherboard's website, download them & use F6. Or, slipstream them too - nLite will do it under Integrate > Drivers. AutoStreamer may do it too.
I can help you find the SATA drivers for your motherboard if you post the make & exact model number. G
