Hi Number6, I've been quite out of the loop during these last months was busy with some personal work. I'm happy if what I've published helped you and thanks for the kind words, it is much appreciated. I can also notice that you've find solutions for your issues with some other users; which is great! But there is something that I would still like to correct: changing the "byte" word to "bit" within the generated DSDT shouldn't be your first option. It is only a solution for those who are left with no other options for whatever the reason might be. I would still recommend (something also being recommended by RehabMan) that you generate your DSDT before making use of any DSDT fix masks, except for "Fake LPC" which I said should always be used in the case of the Rampage V Extreme. The method is already mentioned in the guide.
I have not really been investigating eSATA (not really a fan of, since I don't own such device yet) but it should work directly as far as I know. What is exactly your issue with the eSATA? I suppose that you have an eSATA port which is within your chassis. Which cables comes out of the e-SATA port?
