Efika models currently exist running two versions of the "1.3" Open Firmware.

The firmware marked with built-on date of "20070122" was used for all production runs after this date. This Firmware Update has been released to bring all current Efika models to a common firmware version. The update is recommended for all systems running Open Firmware version "1.3" with an /openprom/built-on property of "20061107".

The only user-facing change is automatic enabling of the internal AC97 bus.

Instructions: Extract the ZIP archive to a suitable boot device such as a USB drive. Simply boot the update file from the firmware "ok" prompt:
