Adaptec 2810SA SATA RAID Driver

Trying to run an Adaptec 2810SA SATA RAID Controller in a dual Opteron system running SuSE 9.0 AMD64. The problem is that the driver (aacraid-drv_1.1.5-suse9.img) for Suse 9.0 AMD64 from the Adaptec site, cannot be read by Yast at install time. The file was dd'd and copied to floppy apparently successfully. Has anyone had the same problem and does anyone have a solution. Better yet, does anyone know of a driver for Suse 9.1 AMD64. Janis
