Enabling SATA Mode and Selecting Option ROM Mode
Step 1
Set the SATA mode for managing the two boot drives:

when prompted to enter the BIOS Setup utility.
b.
Choose the
Advanced

Select
PCH SATA Mode
and then choose one of the options from the dialog:
–
AHCI—Not used at this time.
–
Disabled—The embedded RAID controller is disabled.
–
LSI SW RAID—In supported server versions, you can manage the internal SSD boot drives or
the front-facing drives by using the server’s embedded SATA RAID controller.
Note
Before you change from LSI SW RAID mode to AHCI mode, delete all the RAID volumes
configured in the connected physical drives.

If you selected LSI SW RAID mode and you want to set the option ROM mode, continue with the
next step. If not, skip to
