I just hooked up my 2 HDDs into a RAID array, the RAID setup said they are online and the creation was successful.
when I go to install windows 7 the installation tells me that it can't find DVD drivers.
OS: trying to install Windows 7 HP.
HDD: WD 500Gb *2
Many motherbds have one or two sata ports that you can swich to ide or ahci and sometimes raid. Often they are the last two sata ports (4&5 or 5&6) Set them as ahci and plug your optical drive in there.
You can use ide mode if you want as an optical drive wont need the bandwidth of either bus, I just use ahci in case later on they realize they want more hdd/ssd's and they put the optical on usb.
