If you are still having problems with this, I sugest you try the webmin
interface, it has a great section on the hard disk parameters... and you can
choose all the options and then test the result.. I used this to see how far
I could push the drive (a 7200rpm 2mb cache UDMA 100 Western Digital) and
the ide interface before it failed.. I am using the standard 7.2 kernel, and
a bx motherboard. (which by default only supports udma33) and I got truely
amazing improvments..
give that a shot and see how you go, there are alot more settings then just
choosing dma mode.

Subject: [expert] Enabling DMA on IDE Disk drives.
I have a problem in Mandrake 7.2. Whenever I enable DMA access to my to
my harddisk my computer hangs and I see the following messages in the
message log:
kernel: hda: timout waiting for DMA
kernel: ide_dmaproc: chipset supported ide_dma_timeout func only: 14
kernel: hda: irq timeout: status=0x50 { DriveReady SeekComplete }
Enventually, DMA is disabled. I'm seeing this problem with the
production 2.2.17-21mdk kernel, my recompiled 2.2.17-21mdk kernel, and
the 2.2.18-14mdk kernel. I had previously used Mandrake 7.0 on this
same computer and was able to get DMA access to work by getting the
2.2.13 kernel source from kernel.org and adding the backported ide patch
to the kernel. My desktop computer also runs Mandrake 7.2 and has DMA
access enabled. The computer with problems is a Dell Latitude XPi CD
(Pentium 166 MMX) (No laughing please) with 80 MBytes of memory and a 2
GByte IBM disk drive. The chipset is identified as CMD643. Any and all
suggestions will be appreciated. Thank you in advance.
Best regards,
Arnold
