(especially for all the people w/ 4.6 setup problems) I've been trying to get DMA to work on ATAPI CDROMs for quite a while now to no avail. All my FBSD boxes are SCSI-based, but many of them have IDE CDROMs. I always just thought using PIO for a fast drive was dumb, but it worked, and the HD's are all SCSI, so I didn't bother any further with it. I tried this option to the kernel configuration file: options ATA_ENABLE_ATAPI_DMA But it never did anything. Now I see that doesn't even appear in the LINT file going back to 4.3, so it's probably old/deprecated. Thanks to your suggestion, I now have DMA working on an old ASUS P2L97 board (dmesg shows "WDMA2") and an Intel L440GX+ Dual P3 server system. (dmesg shows "UDMA33") -- Philip J.
