ThunderLink SH NVRAM Settings
The settings in the NVRAM tab vary depending upon the
selected Adapter and the operating system.
Back up system data when installing or changing
hardware configurations.
Use caution when making changes to NVRAM settings and
only make changes to those with which you are familiar.
Entering invalid or incorrect settings when using an NVRAM
configuration utility such as the ATTO ConfigTool may cause
your Adapter to function incorrectly. Once you have made
the desired changes, click
Commit
to save the changes.
Changes do not take effect until you reboot the system.
If you do not want to make any changes, you may choose
one of the following:
•
Defaults
: restores the Adapter to factory default
settings. The
Commit
button must be clicked to save
any changes.
•
Restore
: reverts to the NVRAM settings saved the last
time the
Commit
button was used. Clicking
Commit
is not necessary when restoring.
SAS Address

Displays the SAS address assigned to the Adapter. The value
cannot be modified.
Boot Driver
Choices: enabled, scan only, disabled
Default: enabled
If enabled and disk drives are detected during the bus scan, the
BIOS driver remains resident. If disabled, the BIOS starts, resets the

Scan Only
is selected, the BIOS driver scans the bus and displays
the Adapters attached, then unloads itself after a brief delay.

Choices: enabled, disabled
Default: enabled
When enabled, requires the firmware to respond to periodic
activity. If the firmware does not respond, the system driver resets
the firmware on the
Adapter.

Default: enabled
When enabled, the Adapter driver sends multiple simultaneous
commands to NCQ capable SATA disk drives.

Adapters to appear.
Device Wait Count
