The placement of the ide0_enable lines is important. I think they should
_not_ be within the IDE section. Check src/mainboard/asi/mb_5blmp/Config.lb
for an example which worked for me, and please report if that fixes the
problem.

Uwe,
I'm still having problems. The ideX_enable register values are within the "chip southbridge/amd/cs5530" context in my Config.lb, which matches the ASI mb-5blmp you cited.
This is grasping at straws, but my Config.lb inconsistently uses tabs and spaces... any issues there, beyond aesthetics?
Anyway, FWIW, I attached the Config.lb I'm working from. Any hints appreciated.
thanks,
Jonathan
