No, it doesn't, but make sure that SATA is enabled in the BIOS under Integrated Devices.  You might also try clearing the NVRAM using the jumpers on the motherboard.  This will clear all the BIOS settings and force BIOS to rebuild its hardware and configuration list.
I just purchased a Dell Poweredge 830 server.  It came set up with a raid 5 configuration via a Dell 6 channel CERC card and to boot from a network boot device.  I'm trying to change the configuration to boot from an internal HDD.  I've taken a 250 gb drive from the working raid array (replaced the original 3 drives with 320 GB drives) and am trying to get the server to recognize the new drive.  The drive is connected to the SATA 0 slot on the motherboard.  I've disabled the network boot in the setup screen boot order, but when I set the SATA Port 0 to AUTO, the program displays 'UNKNOWN DEVICE'.  I've tried connecting the drive to the SATA 1,2, and 3 slots with the same result.  I've tried replacing the HDD with another from the working array with the same result.  I can't get the computer to see the new drive.  Additionally, and consistent with the recognition problem, the boot order will not display a HDD boot choice.  I'm stymied as to what to try next, any suggestions much appreciated.
