This text document addresses various hardware support questions
_______________________________________________________________________________
You can reduce the speed of IDE CD-ROM drives with hdparm or a program called
setcd. It works like this:
hdparm -E [speed] [cdrom device]
setcd -x [speed] [cdrom device]
You can also try
echo current_speed:4 > /proc/ide/[cdrom device]/settings
but you will need root privileges. The following command may also help:
echo file_readahead:2000000 > /proc/ide/[cdrom device]/settings
_______________________________________________________________________________
tune your CD-ROM drive with hdparm:
hdparm -d1 -a8 -u1 (cdrom device)
This enables DMA access, read-ahead, and IRQ unmasking (read the hdparm man
page for a detailed explanation).
Please refer to "/proc/ide/[cdrom device]/settings" for fine-tuning your
CD-ROM.
