>Release: FreeBSD 4.0-CURRENT i386
>Organization:
>Environment:
Thinkpad 770X with CS4610 PCI accellarator CS4239 sound configuraiton.
I believe the TP660 has the same setup.
>Description:
Until we can get the PCI CS driver to handle non AC-97 codecs,
we should attach directly to the CS4239 and run in ISA
compatibiliy mode. Unfortunately, all of the CS resources
on the board have a slightly different logical ID than the
normal ones. They use CSC01XX instead of CS00XX. Perhaps
this is to indicate that there is a PCI accelerator attached?
>How-To-Repeat:
Add the pcm driver to your kernel config and boot that kernel.
>Fix:
