Hi guys dabbling with RIS at the moment have a few questions for the gurus

Firstly when setting up RIS you only get a option to use one install image and create a directory for the install files, Well this is a snag because I need the clients to be able to access both XP home and Pro and a variety of images so is there a way around this or am I being a numpty here.
On to the next obstacle so I fired up my shiny new RIS server and connect a Tosh Laptop to it all went well DHCP is working and I was given the option to install Windows so I selected Windows XP Pro and off it went but it stalled at the first hurdle and started moaning at me about Windows not having the right NIC driver. So is there anyway to inject drivers into a install config?
Am I right in thinking with a variety of different kit I am going to end up with different images for machines which need different network drivers seems to be more work then I originally expected lol ohwell.
Thanks for you help
