Thanks Magnus

Did you also enable it to run at boot in MDK control center? You can check if the settings were made after reboot by using hdparm again (as root):
do 'hdparm /dev/hda' (repeat for every drive)
[EMAIL PROTECTED] src]# hdparm /dev/hda
/dev/hda: multcount = 16 (on) IO_support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 1 (on) readonly = 0 (off) readahead = 8 (on) geometry = 9732/255/63, sectors = 156355584, start = 0
You speciefied -u -d -k, this maps to unmaskirq, keepsettings, using_dma
Happy hacking...

This is great ... I was looking for qa way to do this :) I did you say and put in a script in
/etc/init.d/idedma (the script you attached). I wonder ... if there a way to see that the script is starting correctly and the settings are really made to my system?
Anyway ... thanks for the tip

First of all, what kind of system are you on (CPU - RAM), which burner are we talking about?
Is it an IDE burner with SCSI emulation?
What could help a lot is tune your disc devices with hdparm (I got a huge boost out of this). Install hdparm with 'urpmi hdparm'.
First turn to your hard drive (/dev/hda I will assume), since it is the
source of data for both your writer OS and programs, it needs to work
optimal.
- check the current settings and mail the output to the list, this way
we can advice you better.
hdparm /dev/hda
Now, make sure you have the specifications of your devices handy.
I use these settings for my Hardisk: 'hdparm -c1 -d1 -k1 -u1 -X69 /dev/hda' Breaking it up: -c1: turn on 32-bit disk access -d1: turn on DMA (is probably on already) -k1: keep settings over bus reset (you need this) -u1: Unmasq IRQ (reduces waits between different disk operations) - Watch out with this one, it has been known to cause system instabilities on some motherboards/harddisks, but it works fine for me. -X69: force IDE-DMA Mode5 (UDMA 100) (adapt to your need, check 'man hdparm'
Test them out to see which one suit you best.
Now do almost the same for the cdrom/dvd/writer devices (e.g. /dev/hdc) 'hdparm -c1 -d1 -k1 -u1 /dev/hdc' 'hdparm -c1 -d1 -k1 -u1 /dev/hdd' Again, test it carefully.
If you are satisfied with what you got, put it in a startup script like the one below (which is /etc/init.d/idedma) Then open the Control Center, go to system - services and set it to run at boot.
--> done
Additionally you can also switch filesystems to get an even better performance. I found ReiserFS very fast, XFS has been reported to be great too.
Good luck and have a lot of fun!

Dear all,
Recently, I bought a CDR. While burning CD using xcdroast at 48x, I can barely move my mouse or do anything else. It is still very smooth burning cd and surfing net under windows 2000. How should I tune my mandrake 9.0 for better performance?
Thanks,
