Dear SATA subsystem folks,
please keep my address in CC list since I am not subscribed.
This is a reply to my message to the coreboot list [1] and I am adding
more current information to it.

The guy at the computer shop said that under MS Windows you have to set
a jumper to get this working and I also found that in the FAQ of Western
Digital Web site [2]. But setting the jumper did not change anything.
The `dmesg` output is the same.
Also looking at the VIA controllers on their site [2] it does not match
the one I am using, so this problem might not be related to this at all.

This problem is reproducible with Linux kernel 2.6.32 and 2.6.39 on a
Debian Sid/unstable system.
Any insight or help is much appreciated. Searching for
linux-ide sata II via chipset udma 100
did not find anything useful.
Thanks,
Paul
