is necessary to change the settings in the interface
This patch should also be applied to 2.4. I don't currently have a
2.4 tree around.

According to the datasheet, ht6560b only supports up to PIO mode 4.

Hi,
With digging into the code...
I think the ht6560b controller supports DMA. At least it did so in 2.2
(where hdparm could still turn it on). DMA in 2.2 would improve the HD
from about 1M/s to 4M/s. So that's quite interesting.
Also the datasheet claims that there is full ANSI ATA-4a

The data sheet doesn't. It's a PIO controller capable of PIO4 with 32bit
host to cpu transfers are best.
Hmm. But what do you then think that 2.2 did?
I mean it now does 1.15M/s and in 2.2 it would do ~4M/s with DMA on.
Alan,
