Kernel 2.6.5, hdparm dma, and AK72
 

Hello all,

I'm using slackware 9.1 with kernel 2.6.5. I'm trying to tweak my hard drive to perform better by using hdparm, but apparently I didn't compile something in the kernel that I needed to...

I'm using an AOpen AK72 motherboard (can't show the url...grr...just do a google search on AK72 and it's the phase out one) and a Maxtor 120 gig hard drive (I know, I know, eww). I recently switched from Debian to Slackware, and I think I missed some setting that I had in the kernel beforehand. When I do this:

root@galadriel:/# hdparm -d1 /dev/hda

I get this:

/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
root@galadriel:/#

This is not good. I don't want to enable random chipsets and quite frankly, when it comes to chipsets, I'm lost. All I know is that my (two) chipsets are VIA KX133 and VIA 686B.

Any help would be greatly appreciated. Thank you.

Post bump and update

Got a bit of a problem: when doing hdparm -tT on the system, I get a fast cacheing, but as far as the read ahead, it's insanely slow (2-3 mb/sec, not good). This seems to be a consistant problem with the VIA stuff...ideas?

I think I might have it, but I won't be able to test until I get home today.
