What am I doing wrong? The drives probably don't support any UDMA modes. WDMA modes aren't enabled= =20 for atapi devices because there's a very large number of devices which don'= t=20 implement them right or not at all, yet claim to support them. You can enable whatever DMA modes those drives support with the atacontrol= =20 utility after the kernel has booted up. =2D-=20 ,_, | Michael Nottebrock | lofi@freebsd.org (/^ ^\) | FreeBSD - The Power to Serve | http://www.freebsd.org \u/ | K Desktop Environment on FreeBSD | http://freebsd.kde.org --nextPart2475508.GuTn7KHHVK Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (FreeBSD) iD8DBQBCkMKZXhc68WspdLARAlpjAJsHK7NYdfQUynXIXURup0tTx5jgKQCfWoDv 0Dys7Yazr8kHyO/TuuF+BK8= =LK+g -----END PGP SIGNATURE----- --nextPart2475508.GuTn7KHHVK--
