Description

SATA
• AHCI Mode
• RAID Mode
• Off
Enables you to set different modes for the embedded
SATA controller(s).
Note: Be careful when making changes to this field.
The OS previously installed on the SATA hard drive
under a particular mode may not boot after the SATA
controller(s) is changed to a different mode.
Security
Freeze
Lock
• Enabled
• Disabled
Specifies whether BIOS sends Security Freeze Lock
command to the embedded SATA drives during POST.
This option is applicable only to ATA and AHCI mode,
not the RAID mode.
Enabling this feature prevents changes to all SATA
security states until a following system reset. This
feature is useful to stop virus and malware from
erasing your drive or setting up a password attack.

Cache
• Enabled
• Disabled
Allows you to enable or disable Write Cache on SATA
drives during POST. This option is only applicable to
AHCI mode, and is not applicable to RAID mode.
Port A (B,

• Auto
• Off
For Embedded SATA settings in ATA mode, set this
field to Auto to enable BIOS support. Set it to Off to
turn off the port.
Note: In case of AHCI mode and RAID mode, this field
is grayed out because the BIOS always enables the
port.
