Hi
I have problem with DMA with cdrom on my laptop
[EMAIL PROTECTED]:~/Documents$ sudo hdparm -i /dev/hdb

IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4

AdvancedPM=no
Drive conforms to: ATA/ATAPI-5 T13 1321D revision 3: ATA/ATAPI-2 ATA/ATAPI-3

It uses multi word dma instead of ultra dma
If i want change it by hand to uldra dma 66
