Hey everyone, I want to upgrade my Compaq Presario SR1350NX from XP HOme to XP Pro. XP Home SP2 is installed. I have XP Pro original release (no service packs) on CD. My question is about slipstreaming the drivers. If I'm only going to upgrade, do the drivers need to be slipstreamed into the XP Pro install files, or will the upgrade process use the existing drivers? I would do a clean install, but have found that some of the driver installation files are problematic. The sound driver installer reports back that there's not enough room on the C:\ drive to install the driver. (200Gb disc, so there's plenty of room) Thanks Dave
