Hello

I've seen that other people are having trouble with this too, but didn't find a solution.

So my hardware is:
LG DVD-writer 4163B
memorexx CD-ROM writer
Abit nf7-s (v.2.0) nforce2
AMD 2600+ @3200+ (no errors)
2x512 kingston DDR400
SATA: Seagate 200G sata-drive
gainward Nvidia 5600 256MB

And my software:
Debian unstable with 2.6.10 kernel.
WinXP on the side for now maybe getting rid of it.

And I'am having trouble with my ide cd-rom and dvd because they don't get dma.
So they are wery slow and can't watch any dvd's that slow.

The command hdparm -d1 /dev/hdx (x= a or b, a is dvd and b is cd-rom) gives the result:

BirdFarm:/home/miqu# hdparm -d1 /dev/hda

/dev/hda:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
BirdFarm:/home/miqu#

and hdparm -I :

BirdFarm:/home/miqu# hdparm -I /dev/hda

/dev/hda:

ATAPI CD-ROM, with removable media

So any ideas for using dvd and cd with dma?

Or what am I doing wrong?
Bios Ide settings are on auto. I'am sure that I'am forgetting some info but it's my first post so sry.

My conf , lsmod , lspci and dmesg are in my homepagearea.
If you need more info please ask I'll make more files available.
Can't link because this is my first post.

"users.utu.fi/mjrast/linux" has txt files (just copy paste to addressbar)

So I tested the drive with my windows xp. There the reading of dvds works fine but writing screwed up with a message(from nero) scsi command failure...
Might the drive be broken, funny because it reads fine in winxp.

So my IDE controller is broken again. It doesn't take master drives at all. So made my writer slave and gave it a go and burning works fine in windows. But under linux can't give DMA to the drive still.

Any help would be appriciated

I think it gives my drive udma100 at startup but no dma? (in dmesg)
And in later parts of startup checks the drives again and says something like "ide0 allready assinged"???
