While copying some RPMs from a CD to the hard drive, I noticed the

took a really long time and ran "hdparm -Tt /dev/hda" to see what the
transfer speeds were. The buffered disk reads were somewhere in the
neighborhood of 7MB/s, which lead me to believe DMA wasn't on. hdparm
and dmesg confirmed that. I tried turning DMA on with hdparm to do some
more testing, but I got the error:
HDIO_SET_DMA failed: Operation not permitted
We're running the latest RHL9 kernel, 2.4.20-20.9, a Hitachi 60GXP
Deskstar drive, and using ATA-133 compatible cabling. My suspicion is
the motherboard, a Gigabyte 7VT600-L based on the Via KT600. I'm not
sure if the kernel we are using has support for a motherboard this new.
Searching Google produced quite a few hits, but most were pretty old
and all seemed to suggest that IDE driver support was lacking in those
instances. So my question is, will the new Fedora Core 1 kernel have
the support we need to get DMA working on this setup?
I believe you're correct. I have a number of KT600 boards on systems at
work, and Fedora Core 0.95 (plus current updates) works fine on all of
them with expected DMA support, whereas Red Hat Linux 9 did not. If you
hold off a few days and use BitTorrent to grab the Fedora Core 1 ISO
images you should be right as rain.
