Hello list,
I installed the latest snapshot on an Intel D945GCcr mobo
which supports SATA-300 (sata2) , plugged in some hard
disks, all of them Western Digital WD3200AAKS,
wich according to WD website those work at 300 mb/s.
(http://www.westerndigital.com/sp/products/products.asp?
driveid=299language
=en)
but OpenBSD doesn't seem to recognize them with the
AHCI driver , and they are recognized as UDMA5 instead.
I'd like to enable full speed on this disks, any tips?
OpenBSD will use the interface that is presented by the hardware/bios
configuration. Even if your SATA controller is AHCI capable, it wont
be used in OpenBSD unless the BIOS configures it to be in the AHCI mode.
As for the speed difference, I don't think which mode the controller
is in affects the speed it talks to the disks at.

Here i paste a full dmesg :
