Having problems getting my DVD-ROM to work using DMA. I have a Toshiba
SD-M1212 DVD-Rom set up as a slave to my CD-RW. My CD-RW has DMA in
Linux but the DVD-ROM. Both have DMA set in the bios. Somewhere the
DVD-ROM DMA setting is getting turned off. I have tried to turn on DMA
using hdparm -d1 /dev/hdd. I get an error message syaing operation not
permitted. However, if add hdd=ide-scsi as kernel parm then I DMA is
set. However, players do not see the drive correctly.
Anyone have clues where to start looking to solve this issue?
