The EPOX board uses : atapci0: <VIA 82C686 ATA66 controller> The 596A is usually found on Super7 boards or manufacturers trying to cut corners. Actually it is a better solution because the software codecs and AMR are both junk IMOP. Most users add a sound card and 'god only knows why' you would ever use an AMR slot. The ATA66 is the obvious benefit though. I think EPOX went back to it on their Super7 boards versus a 686A. -- Ted Sikora Jtl Development Group tsikora@powerusersbbs.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
