Enable DMA on DVD drives


Can anyone advise how I enable DMA on my DVD drives (DVD playback is choppy) and get it to do so on system boot every time? Seen lots of advice and they seem to make assumptions about what the drives will be called - I have 2 hard discs hanging off SATA connections and 2 DVD drives on 2 of the four IDE connections...

Any help appreciated as this is the first time I've got a distro to actually install in about a year

I did a Google search, and it's not looking good for SATA:

Search my posts for the last couple of days I have answered this about four times and am getting tired of writing it every time. In fact here is one of them in the similar threads at the bottom of this page.

Sorry, I was getting frustrated after working for hours to get this sorted without success last night - perhaps in hindsight I didn't make myself clear.

I know what commands to use to enable DMA, but all the threads make *assumptions* about where my DVD drives will be mounted. I have an MSI board with FOUR SATA connectors and FOUR IDE connectors so it's not that simple. My DVD-RW and DVD-ROM drives are connected to two of the latter.

Can you tell me what command I can use which will *tell me* where my DVDs are mounted - I don't want to spend ages on guess work by trying hda, hdb etc etc etc

Many many thanks (I am a linux noob btw so please don't be harsh)

Try the command below and you should get similar output.

Code:
>$ dmesg |grep -i dvd
hdc: HL-DT-ST GCE-8483B, ATAPI CD/DVD-ROM drive
hdd: BENQ DVD DD DW1640, ATAPI CD/DVD-ROM drive
hdd: ATAPI 126X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache

This works for me - add hdparm -d1 /dev/hdc to /etc/init.d/bootmisc.sh
