Many of the better mobo's include a RAID chip on the mobo in addition to the one that may be part of the chipset [some newer chipsets only support SATA RAID.]. The same option can exist fot SATA RAID, only RAID or also use for IDE drives. [SATA drives are also a form of IDE drive, but not ATA]
You must review the articles to see if the RAID controller will only support RAID or if the controller will allow running ATA drives and also ATAPI drives, Not all of the chips do. Gigabyte's ITE gigaraid chip allows all options. So allow ATA but not ATAPI.
No real way to find out but read such articles.
