The easiest and quickest way would be to disconnect the SATA drive for
install and install Vista on the 40GB PATA drive. This will allow you to
install without the SATA drivers. After the install is complete, you can
re-connect the SATA drive.
If you have the SATA drivers handy, go ahead and install on the 160GB drive
and press "F6" when requested to put in the SATA driver disk. It has better
performance than the older 40GB drive. Although it may not be too noticeable,
the SATA drive has a better interface, as well as probably having a higher
cache onboard.
So, use the PATA drive for an easy install. If you have the SATA drivers,
install Vista on the SATA drive. Easy will equal slightly lower performance,
though.
