Enabled Indicates the EFI driver is controlling the adapter,
or will attempt to control the adapter upon
reload.
Disabled Indicates the EFI driver is not controlling the
adapter or will discontinue control of the adapter
upon reload.
Error Indicates that the EFI driver encountered a
problem with the adapter. You can view and
modify settings for the adapter but the available
information and functionality may be limited.
Boot Support Indicates whether the adapter is eligible for configuration utility
software control, or is reserved for control by other software:
Enabled BIOS & OS, Enabled BIOS Only, Enabled OS Only, or
Disabled.
Enabled BIOS & OS The SAS controller is controlled by
both the BIOS and OS driver.
Enabled BIOS Only The SAS controller is controlled
only by the BIOS. This setting may
not be supported by all OS drivers.
For example, it is not possible to
disable an adapter in a Windows
driver.
Enabled OS Only SAS controller is controlled only by
the OS driver.
Disabled SAS controller is not controlled by
the BIOS when the SAS controller
is loaded. However, the adapter is
visible through the Configuration
Protocol.
Changes to the Boot Support setting are reflected in the Status
field of the Adapter List menu. However, the new setting does
not take effect until you reboot the system.
