not a great idea. it would take a lot of time to install it but.
also u would need to pass the copy protection and copy the contents of the nfs cd to the unattended dvd. and some of the setups just like to be called from their own cd's (copy protection).
also its 2cd's so it will at some point request the 2nd cd...
I suggest this:
first copy the cd1 and cd2 to just 1 folder in the hdd.
try to install it from there. if it works without any problems then post back in here
I'll try to dig up the silent switches
its done by installkitwizard...
you can find the registry path to the serial here
