Re: output from hdparm
Add: options ide-cd dma=1 to your /etc/modules.conf file This should do the trick.

Re: output from hdparm
Good one! thanks, also I forgot to write that I have a cdr-w on the same machine and dma was always working for it. so with your answer I recalled that in order to let the cdr-w work I had to add hdd=ide-scsi to the kernel in grub. that is why I could set up dma on my cdr-w and not in my dvd so I added hdc=ide-scsi for my dvd and also worked. thanks for the tip.

Re: hdparm
apperently it is a kernel compilation problem: I booted the kernel from mandrake with the parameters you sayed and it worked. There is a 50% improovment on benchmarks, but in real life not so much. I looked at the docs and the kernel configuration and have not find what I should set on.

Re: hdparm
Actually, that's how I found out about the cdrom :) I had a weird problem - my 7200rpm / ATA100 hdd couldn't read/write more than 2mb/s on Linux. Now, after loading the VIA IDE module, and enabling DMA - It reads in 22mb/s! I wonder how many people have the same problem and they just don't know it. (I actually worked with it that way for months, using 10% of my hdd speed).
