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

UDMA setting is a legacy of PATA, and tends to have very little 
relevance to SATA.

I wouldn't worry about it unless you are actually measuring low 
performance, as opposed to just looking at dmesg.

The UDMA speed doesn't really make a difference with a SATA drive. The 
transfer speed is really controlled by the SATA link speed (1.5/3/6 
Gbps). It only really matters if there is a PATA-SATA bridge somewhere. 
Some manufacturers never supported UDMA/133 so there's a behavior 
difference between drives in that some indicate support and some don't. 
The transfer speed has to be set in most cases for compatibility reasons 
but it usually doesn't actually affect anything.
