Gigabyte: ga-ma78gm-s2h: bios sees sata hdd as ide ? Help

I just purchased a new setup and when i boot up and go into the bios it shows the sata drive as ide. I only setup the date and time and left everything else as default. I want to install the OS but not use a raid setup, should it not show the drive as sata drive instead of a ide, or is this normal? Do i need to change something or add drivers or what? Please help me on this.

It shows the sata hdd as IDE channel 2 Master
it shows the sata DVD-writer as IDE channel 1 Master ATAPI ihas220 6 8L04

Thank you

If i decide to use AHCI mode and i have the bios setup as this,
onchip ide channel Enabled
onchip sata controller Enabled
onchip sata type AHCI
onchip sata port 4/5 type As sata type
i understand that windows vista business w/sp1 has a generic driver so i would not have to install a driver for AHCI mode until after i installed the OS.
is this good to go as far as installing the OS. or am i missing something
Thank you
