Important Information About "Drive Firmware Update" 

This extension will load during boot time.  It detects the firmware version and drive type of your internal hard drive.  If the firmware and drive type require update, the extension will download the new firmware into the drive.  Once the install occurs, the extension is no longer required.

Installation Procedure:

1.  Drag the ÒDrive Firmware UpdateÓ extension in the Extensions folder located in the System folder.

2. Restart the computer by choosing ÒRestartÓ in the Special menu.

3.  As the computer is restarting you will see the  ÒDrive Firmware UpdateÓ icon displayed along the bottom of the screen.  The icon will be displayed only if the firmware update has been performed successfully.

4.  After the system finishes booting, choose ÒRestartÓ from the special menu.

5.  If the firmware update was successful, the icon will not be displayed along the bottom of the screen.  The extension can now be removed from the Extensions folder.
