I have also a x98 air II (HG5N), i want to install a dual boot Bios in order to install win8.1 and upgrade to android 5.
My stock official Rom doesnt have the UpdateIFWI, I tried installing it but didnt work (stayed at “upgrading” message….).
So i decided to follow your advise and install the ORIG 4.4.4 2.0 rom with stock UpdateIFWI, i loaded the rom to the Intel manufacturing tools and tried to enter DNX mode (fast boot mode), i am new to these procedures, i followed the Chris Youtube guide, but my tablet doesnt enter Dnx mode when i press Vol+- and power buttons simultaneously, it just boots normally to android. Do i have to install something to my tablet, to enter DNX mode?
I want to use Bios 2.02, is it appropriate for HG5N tablet?
