Anyone can help me check if I'm right?

Each byte is for each channel, LSB is secondary slave. Interesting bit is bit 4
1 = 80PIN.

Mine:
> 50: 07 e6 07 e1

So: I have 40 40 40 40

 > 50: e6 e2 17 e0

Yours: 40 40 80 40

So the silly BIOS is doing something wrong :/ I would expect 40 40 80 80.
I will try to play with the cables to see what I can get.

regards
Rudolf
