Can't install SATA drivers

[parados]

I am trying to install linux on a new system being built with Gigabyte 7n400 Pro2 board. No matter what I do it refuses to see the 2 SATA drives.
I first installed Fedora Core1 to an IDE drive but couldn't see the drives at all. Not sure if the sata_sil driver was in Fedora I switched to Mandrake 10 and had the same problem. DiskDrake refused to see the drives at all. After hours of searching, I decided to just try installing directly to the SATA drives but the install doesn't recognize the drives. Sata_sil is being installed but then it tells me that there is no drive to write to. The drives are there in bios. I even put a copy of Windows2000 on an IDE drive and Windows saw the drives just fine including formatting them.
Anyone have any idea of what driver I am missing? The install asks for one but it lists Sata_sil under the hardware list.

Do you have more than one SATA controller (chipset) on that board? I recently had the same problem but reversed (found the SATA drive, couldn't find the IDE drive), and once I moved the IDE cable from one chipset to the other, the Mandrake installation found it just fine. Very confusing, but it worked. Would something like that be an option on your mobo?

Have you tried Fedora Core Release 2 ?
I run it, and my system has 1 SATA drive - drivers load and access hd perfectly.
