Drive shows up as SCSI

86i13B06A267CECFCE2My Gigabyte motherboard went dead, bios screwed up. I bought a new motherboard, ASUS P5N-T Deluxe. I also got a new drive, WD Caviar Black WD6401AALS. Installed Windows 7 but when I boot up is says WD6401AALS during the POST. When I right click on the drive properties  its called, WDC64 01AALS-00E8B (SCSI).  The drive seems to be operating normally. Has anyone had this problem ? Can anyone let me know how to correct this?
