Has anyone found a meaning to the directions in the book under the picture of Neks/Nex Isle?

For those interested in what they say:

FAAM KO UHU AR. PALA KO AR KO UHU NEL.
AR NA LAM FAAM KO.

Sorry, I had written the instructions wrong. the last word should be NA

Like ages ago.
It guides you to a place where you can dig up & fight the boss from the first Legend of Grimrock game.

Google it or solve yourself (there is a similar puzzle in the game in the archives, so you should know how to decrypt this text by now) — choose, what suits you best.

I knew about the archives which is why I'm asking about these directions. Thanks.
