No change. I still get all 0xff's (not all zeros like I said earlier)
I think I'm a victim of my own cleverness. Digging back into the code
I now rember that my port is _not_ just a port of the V1 assembly.
Its a total rewrite.
My port is heavly based on the AMD solo board. Thats the mainboard
that had a superIO closest to mine and out of all the boards I looked
at the AMD north and southbridge code was the cleanist and easiest to
follow. So I basically took the smbus code from the amd8111 and
changed the register defines and bit flags to match the i440bx.
Well at least thats the theory. Obviously I got something wrong. The
structure for the sm_bus read already has a delay function in it. It
was only one out(80,80) I bumped it up to 6 but no change.
I suspect that one of my flags is just incorrect. What needs to
happen is lots of debug prints to watch the status register and verify
that a single read really does the right thing.
I was kinda hopeing it would just "work". Sigh.
I can't really mess with it again till this weekend but if someone
else wants the code let me know.
