Trying to install SL5.0 on new Compaq Presario with 2 hard drives.  Scree
n
comes up "No driver found.  Unable to find any devices of the type needed

for this installation type. Would you like to manually select your driver
 or
use a driver disk?"  

Choosing "Select driver" brings up a list but where to find any of these
because I don't know if they are for the hard drive, the motherboard, PC 
bus
etc ?  

I checked the website of my hard drive just installed, for this purpose
(SL5.0) so I can keep Vista on the original drive too.  But they say no
drivers are needed for my new hard drive, that it's a controller for the
motherboard or something else.

Anyone familiar about where to start?
Thanks for your time.  Sincerely,
R.Soares
