Hi,
Over the weekend I built my new computer using the ASRock H87M-ITX motherboard (BIOS is up to date with version 1.50). I have three hard drives connected to the motherboard:
So far I am just mucking about with the BIOS and I haven't installed any OS yet. In fact neither of the three disks have anything on them - neither partitions, nor file systems - they are completely clean and empty. As expected when I let the boot process continue past the BIOS I get an error telling me to select a proper boot partition.
I want to set up the two WD disks in a RAID1 mirroring array using the motherboard's BIOS, but I'm having issues with that. In the BIOS's "Storage Configuration" (under "Advanced") I can select one of three values for the "SATA Mode Selection":
When I select "AHCI" as the SATA mode, the "Boot Option Priorities" menu allows me to select "AHCI-P0 Samsung ...", which is the SSD. The two WD disks are available separately under the "Storage Device BBS Priorities" (where I can set the order of which disk the BIOS attempts to boot from first), but not under the "Boot Options Priorities" menu. So far this is what I expected.
However, when I select "RAID" as the SATA mode, I can create a RAID1 array using the "Intel(R) Rapid Storage Technology" menu in "Advanced", but I no longer see the SSD in the "Boot Option Priorities". In fact I don't see any of my hard drives in the boot options menu.
Why can't I select my non-RAID SSD as the boot disk in the BIOS when I switch the SATA mode to "RAID" from "AHCI"?
Is the "RAID" SATA mode in the BIOS meant to allow me to use a RAID array as the boot disk and therefore allows only RAID devices in the "Boot Order Priorities"?
Thank you for any help you can provide.

Over the weekend I built my new computer using the ASRock H87M-ITX motherboard (BIOS is up to date with version 1.50). I have three hard drives connected to the motherboard:
- 1x Samsung 120GB SSD (purpose: system disk) and
- 2x WD 4TB HDDs (purpose: RAID1 for data).
So far I am just mucking about with the BIOS and I haven't installed any OS yet. In fact neither of the three disks have anything on them - neither partitions, nor file systems - they are completely clean and empty.

- IDE
- AHCI
- RAID
