I have the exact same issue with my Elite.
My arcade pack that came with H0079FL is all good, Slax put it in mode b and did the rest, but my Elite with H0079FK not even recognized in Slax????
Bios sees the drive but Slax doesn't somehow, and I know my set up is complete.
Well, today I'll give Podger's Mode B exe and see what happens.
Anyone one else knows why this can happen? and Please discard the most common errors that we all know about. This is not common.
