Re: Hdparm and 2.4 kernel
Generally you need to be root to use hdparm. I am root! I wouldn't imagine it working it with a non-priveleged user. There seems to be a gerneral problem with hdparm not being happy under the 2.4 kernel -- if I boot 2.2.18 again it works fine. Even more generally you shouldn't need to use hdparm with 2.4.x kernels. 2.4.x has much better IDE support. I get much better benchmark results with DMA set on. -- Chris Howells E-Mail: [EMAIL PROTECTED] ICQ: 93699029 Web: http://www.chowells.uklinux.net

Re: Hdparm and 2.4 kernel
is your kernel compiled with dma support? because if it's not, thats not gonna work. Yup, pretty sure it is. I'll check though. If your chipset supports DMA, along with your drives, and you select the Use DMA when available... option in the kernel, it should already have DMA enabled. If not, I would be hesitant to force it on with hdparm. Hall

I had my kernel compiled with DMA support, passed some command line parameters throug lilo.conf and DMA was not set by kernel; I did it by hand (hdparm). I'm using a Dell OptiPlex GX110 with i810 chipset and a Maxtor 20GB UDMA.
