SATA as hda (not sda)

Hi! I'm try to install SLES 9 x86 64Bit on AMD ATHLON-64 2800+ (ADA2800) 512K/ 800МГц BOX Socket-754 Micro-Star MS-7032 K8M Neo-V Socket754 <VIA K8M800> AGP+SVGA+LAN SATA HDD 120 Gb SATA150 Seagate Barracuda 7200.7 with using CD1 SUSE LINUX Enterprise Server 9 Service Pack 1 for AMD64 and Intel EM64T. Is SATA determination as /dev/hda normal (not /dev/sda)? I'm try with boot option hda=none (/dev/hda not detected, confirmed driver activation for sata_via, error - no hard disks were found for the installation) and without this option (hard disk is detected as /dev/hda). Thank you, Valery.
