Adjusting Adapter settings with the EFI
Configuration Utility
Note
Depending on your configuration, it may be
necessary to adjust adapter NVRAM
settings prior to performing the OS X
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.
Once you have downloaded the 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 install 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.
9
At the prompt, enter exit to return to the rEFIt
boot menu or reset to restart the system.
