Here's the ATA-related stuff I get at boot time: atapci0: <VIA 82C686 ATA100 controller> port 0xd400-0xd40f at device 7.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata1: at 0x170 irq 15 on atapci0 ... ad0: 57241MB <ST360021A> [116301/16/63] at ata0-master UDMA100 acd0: DVD-ROM <Pioneer DVD-ROM ATAPIModel DVD-106S 0122> at ata1-master using UDMA66 I've also got 'hw.ata.atapi_dma=1' on /boot/loader.conf to make sure the DVD uses DMA, since it does seem to work properly with this drive. There should be similar stuff in your boot messages telling you what modes the drives are using. > There is a dvd drive as slave -- and I was able to set it from the default > pio mode to dma mode.

If those are the only two ATA devices in the system, put the DVD on a separate cable -- performance will suck if you try to access two devices on the same cable no matter what DMA mode they're in. Speaking of cables, make sure you've got the disk on a proper 80-way UDMA100 cable.
