One of the CMOS settings of the GA-890GPA-UD3H mother board is "OnChip SATA Type", which includes three choices: Native IDE, RAID and AHCI. Only one can be selected.
RAID is a data striping method and AHCI is an interface between SATA3 host controller and the storage media. I beleive the two can co-exist.
My question, then, is:"When RAID is selected for GA-890GPA-UD3H, is AHCI also enabled automatically, like the Intel mother boards?"
I have this question because Intel recommends the following for the CMOS settings of mother boards they produce (see
http://www.intel.com/support/chipsets/imsm/sb/CS-015988.htm ):
"If you are using a SATA hard drive, the best option is to set your BIOS to RAID mode [for Intel mother boards]. RAID mode provides the greatest overall flexibility and upgradeability because it allows your system to be RAID-Ready
and also enables AHCI."
If Intel does that, I feel Gigabyte may do the same, If they don't, why?
PS: FYI, Intel also describes the steps to set RAID and AHCI for their mother boards, as follows:
To enable RAID and AHCI:
1. Enter the BIOS.
2. Click Advanced.
3. Click Drive Configuration.
4. Enable Intel® RAID Technology.
5. Save the changes and exit the BIOS.
To enable AHCI only:
1. Enter the BIOS.
2. Click Advanced.
3. Click Drive Configuration.
4. Disable Intel® RAID Technology.
5. Enable SATA AHCI mode.
6. Save the changes and exit the BIOS."
