You're running a VLB controller, don't expect it to run a UDMA drive as well as a Pentium machine can. You're trying to compare performance on a what, 16 bit contoller, versus the 32 bit controller on the Pentium motherboard. Of course one is going to be a tad bit slower. :) Rick To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
