Nope. The harddisk is not SATA, it's PATA. See the links I posted
earlier. That's the whole point.
The controller thinks its a SATA device, so there is probably a bridge
installed.
I suppose it's something like that.
It's all very confusing.
E.g. that would mean I must treat my PATA harddisk as if it's a SATA
harddisk, but on the other hand, it's not really a SATA disk, so I
cannot use SATA features.
Maybe an idea to spend a few words on the matter, including the way
you're supposed to configure the kernel for this setup.
Sounds like you've hit on the configuration, in the previous email.
Yes, it does mean no DMA for the DVD drive.
BTW afaik you won't be able be able to control DMA on the dvd drive with
this setup, so I'll stick to my patched kernel for the moment (= both
disk&cdrom are assigned to ide).
That's normal for combined mode. Until libata can do ATAPI (soon!), the
lack of DMA is a necessary evil, since two drivers are trying to claim
two halves of the same hardware.
