Compaq Proliant ML310 Server (No Hard Disks Found)

Dear users, When installing SuSE Enterprise Server 8 on a Compaq Proliant ML310 server, we get a error "Hard disk not found" I assume its because a Smart Array Driver is required. Please may you advise where I can download the Compaq Smart Array 641 boot-time loadable device driver? Do I press ALT then insert the floppy disk during the install process? I have created a driver disk using rawwrite, press ALT at installation, insert disk, but SuSE just does nothing... Does not detect any controller. Any help is much appreciated. Thanks Fareed
