Symptoms
SSD location information in the On-Board Diagnostics Configuration page may be displayed in the wrong order. The issue occurs when setting SATA operation mode to RAID On, installing three PCIe SSD to the motherboard, and booting to On-Board Diagnostics by pressing the F12 key when starting the computer.
| Installed Location on the Motherboard | Location Information Displayed in On-Board Diagnostics | |
| Disk 2 | M.2 PCIe SSD-1 | M.2 PCIe SSD-2 |
| Disk 3 | M.2 PCIe SSD-2 | M.2 PCIe SSD-1 |
Affected Platforms:
- Alienware Area-51 AAT2250
Cause
The disk number from RAID ROM follows hardware port number, not from motherboard location sequence. There is no request to point out that the disk number must be the same as location information.
Resolution
This is working as expected.
