Re: Hard disk access causes high CPU load

Hi, I've found the reason. VIA chipset support was not compiled into my kernel (oops). I've recompiled and now DMA and 32bit transfers are enabled by default. Balazs On Sun, Apr 21, 2002 at 11:12:44AM +0200, Balazs Javor wrote: >Hi, > >Thanks everybody for the help! >hdparm tells me that I don't

Hi, Thanks everybody for the help! hdparm tells me that I don't have either DMA nor 32bit transfers enabled... Before switching it on though, might there be a reason for this? e.g. Is the controller on my Shuttle FV24 (VIA PL133) not supported properly? It says something about not 100% native mod

Oops, I was wrong. Every system I have installed before always has the dma enabled. I just checked and it wasn't enabled here even though I have it on the kernel. So that might be the problem. I will check into this further. Dave -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subjec

Get hdparm package and run hdparm /dev/hda or sda or what ever your root hard drive is, and that will give you information on your hard drive usually hdparm -d1 /dev/hda will turn on dma try hdparm -d1 -m16 -c1 /dev/hda that should take care of most of it. I had the same problem as you and someone

Hi, How can I find out whether the hard disks in my Woody box are using the best possible DMA mode (or any DMA at all)? Allthough I have a relativly slow machine (VIA C3 800 + 256MB), I have an ATA100 controller (VIA PL133) and two Seagate Barracuda IVs. So they should be relatively fast and use
