>Description:
The nVidia chipset AHCI-SATA-Interface nForce 630i MCP73 (Product-ID: 0x07f0)
is not recognized as ahcisata. So the kernel falls back to pciide with PIO.

Patching the ahcisata quirktable gives the desired result and it uses DMA.
>How-To-Repeat:
Boot NetBSD 5.0_BETA (or 5.99.1) with the above chipset.
>Fix:

Following a hint from tron@ this patch fixed the issue:

 Isn't there a BIOS option to switch between pciide and ahci modes ?

 In this AMI-BIOS unfortunately not. I can only select to use any
 SATA-port in the nVidia-RAID.

 OK, so no other way than forcing it to ahci in the driver then ...
