When you use an Ultra ATA controller, you'll be running in EIDE/PIO mode. Re: 3.0-current. You might have some problems with only some "special" controllers. However, the Promise and others (including the PIIX*) work well. You can use full DMA modes (including Ultra), and gain all of the performance benefits. -- John | Never try to teach a pig to sing, dyson@freebsd.org | it just makes you look stupid, jdyson@nc.com | and it irritates the pig.
