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 macOS
installation. For example, you made need to modify the device wait
time or create a RAID group. The EFI configuration utility can be
launched from an EFI shell. Unfortunately, an EFI shell is not included
with Intel Macs. ATTO recommends rEFIt, which is available for free
from http://refit.sourceforge.net.
DMG for rEFIt, do the following to open the EFI Configuration Utility:
1. Burn the rEFIt DMG file to a CD. Do not remove the CD.
2. Shut down the system and insert the ExpressSAS
adapter.
3. With the rEFIt CD inserted, boot the system while
pressing and holding the C key. This will boot the rEFIt
CD.
4. The rEFIt boot menu will appear which contains a series
of icons. Release the C key and use the arrows to
highlight the Start EFI Shell icon. Press Return to enter
the EFI Shell.
5. 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.
6. 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.
7. Use the on-screen menus to configure your adapter. Help
is available at the bottom of the screen.
8. When exiting the configuration utility, if you changed any
settings, the system will restart the adapter so the new
settings take effect.

menu or reset to restart the system.
