How to use %pre to access installtion media

[Siao Yuan Tan]

Dear All,

Please help.  I am trying to copy a driver from installation media to
the hard disk in the %pre section, but do not know how is the path
setup.  In %pre section, can I access the media in /mnt/source and is
the partition already setup in the hard disk, is it in /mnt/sysimage or
something else.

Please advise.

Thanks,
Siao
