SATASelect Options
The following table lists the available and default settings for each SATAlSelect option and the
description of each option. The default settings are appropriate for most systems and appear in
bold type in the table. Adaptec recommends that you do not change the settings.
SATASelect Options Available Settings Description
Controller Configuration
Runtime BIOS Enabled
Disabled
Disabled:Scan bus Controls the state of the BIOS at POST time.
When Enabled, the
HostRAID controller BIOS
allows the controller to act as a bootable
device. Disabling the BIOS allows another
suitable
HostRAID controller to act as the boot
device.
BBS Support Device
Controller When BBS support is set to Device base, the
system’s BIOS will list each attached bootable
device to the
HostRAID controller as an
individual entry. When BBS support is set to
Controller base, the system’s BIOS will only list
the
HostRAID controller in the system boot
order. This is useful in a multi- HostRAID
controller configuration.
Physical Drives Display
during Post Enabled
Disabled When Enabled, attached physical devices are
displayed during system POST. Displaying the
devices adds a few seconds to the overall POST
time.

legacy and non-configured drives. Write cache
enabled provides maximum performance.

feature of the disk drive. When enabled the
