Update of /cvsroot/mplayer/main/DOCS In directory mplayer:/var/tmp.root/cvs-serv13958/main/DOCS Modified Files: documentation.html dvd.html Added Files: cdrom.html Log Message: Some separation and renaming for the next generation DVD dox :) --- NEW FILE --- <HTML> <BODY> <PRE> <A NAME=4.1>4.1. CD-ROM drives From Linux documentation: Some CDROM drives are capable of changing their head-speed. There are several reasons for changing the speed of a CDROM drive. Badly pressed CDROMs may benefit from less-than-maximum head rate. Modern CDROM drives can obtain very high head rates (up to 24-times is common). It has been reported that these drives can make reading errors at these high speeds, reducing the speed can prevent data loss in these circumstances. Finally, some of these drives can make an annoyingly loud noise, which a lower speed may reduce. The recommended way to do it is with a program called 'setcd' . It's kinda old, but won't be too hard to find on the Net. (UPDATE : new hdparm has an option for this !) Use it with : setcd -x [speed] [cdrom device] Also you can try : echo current_speed:4 >/proc/ide/[cdrom device]/settings but you'll need root privileges. I use following command too : echo file_readahead:2000000 >/proc/ide/[cdrom device]/settings for 2MB prefetched reading from the file (it's useful for scratched CDROMs). It's recommended that you tuneup your CDROM drive also with hdparm : hdparm -d1 -a8 -u1 (cdrom device) to enable using DMA access, readahead, and IRQ unmasking. (if you don't understand these, *read the hdparm manpage*) Please refer to "/proc/ide/[cdrom device]/settings" for fine-tuning your CDROM. </PRE> </BODY> </HTML> Index: documentation.html =================================================================== RCS file: /cvsroot/mplayer/main/DOCS/documentation.html,v retrieving revision 1.29 retrieving revision 1.30 diff -u -r1.29 -r1.30 --- documentation.html 22 Aug 2001 16:57:48 -0000 1.29 +++ documentation.html 23 Aug 2001 00:14:51 -0000 1.30 @@ -85,9 +85,9 @@ <A HREF="dvd.html#4">4.
