Apple has released three Extensible Firmware Interface (EFI) firmware updates that bring Lion’s Internet Recovery feature to the Mid-2010 iMac, Early 2010 MacBook Pro, and Late 2010 MacBook Air.
Apple had introduced the Lion Internet Recovery feature on new MacBook Air and Mac Mini models alongside OS X Lion in July. The Internet Recovery feature adds a small bootable install onto a machine’s firmware that allows the machine to connect to the Internet and download the full Lion OS for installation. This feature is a safety net to the recovery partition that OS X Lion installs on every Lion machine’s hard drive.
Now the users of older Macs can have another fallback option when they restore their system.
Apple has yet to offer support for the current Mac Pro as well as older versions.

This update enables Lion Recovery from an Internet connection on iMac (Mid 2010) models.
