3 New Windows OS Installation
When you install a new or different copy of the Windows operating system on a disk attached to an ATTO
ExpressSAS adapter, you must reinstall the ATTO ExpressSAS drivers.
If you are changing the version of Windows you are
using or installing a fresh copy of your current version
onto your system, you must ensure Windows
recognizes your ATTO ExpressSAS and uses its
drivers.
You may create an installation media (disk, CD or USB
flash drive) from a file from the ATTO website, then
use that media to install the adapter and its driver to
the new version of Windows.
Follow these procedures after you have completed
installation of the ExpressSAS adapter and you have
connected storage devices (refer to
Install Hardware
on page 15).
Adjusting Adapter settings with the EFI
Configuration Utility
Depending on your configuration, it may be necessary
to adjust adapter NVRAM settings prior to performing
the Windows installation. For example, you may need
to modify the device wait time. The EFI configuration
utility can be launched from an EFI shell. A built-in EFI
shell is included with many PC platforms. If your
platform does not have a built-in EFI shell, one can be
obtained at
http://tianocore.sourceforge.net
.
Once in the EFI shell, do the following to open the EFI
Configuration Utility:
1
At the prompt, enter the
drivers -b
command.
Scroll through the list of installed EFI drivers
and find the
ATTO ExpressSAS driver
. There
may be more than one entry based on the
number and type of adapter(s). Note the two or
three digit hexadecimal driver handle on the far
left of the screen.
2
At the prompt, enter
drvcfg -s {handle}
where
{handle} is the hexadecimal number from the
previous step. This will launch the EFI
Configuration Utility for the associated adapter.
3
Use the on-screen menus to configure your
adapter. Help is available at the bottom of the
screen.
4
When exiting the configuration utility, if you
changed any settings, the system will restart
the adapter so the new settings take effect.
5
At the prompt, enter
exit
to return to the EFI
boot manager or
reset
to restart the system.
