I have added the tutorial for using 79 Unlock to flash Hitachi ROM v0079FK and v0079FL drives to the downloads section of the site. You can download it here:

or a direct link here:

This will be included when the Textbook tutorial is updated, but because of the influx of people flashing 79 drives, I wanted to get this out as soon as possible. This will give me some more time to make other improvements to the Textbook tutorial.
