I have a DVD drive which is recognised by FreeBSD: acd0: DVD-R <DVD-RW IDE1004> at ata1-slave PIO4 The drive supports DMA, and Windows sets it to use UDMA mode 5 (I think), but BSD does not. I am assume because the device is not listed as supported correct driver? I had a look in ata-dma.c but that file seems to be for controllers rather than devices. Can anyone point me in the right direction for this? -- Avleen Vig Systems Administrator Personal: www.silverwraith.com EFnet: irc.mindspring.com (Earthlink user access only)
