I should. Understood, I use a single 5400 RPM UDMA Ide disk with the new ATA drivers - /usr/obj and /usr/src are on the same partition.

I'd be interested in seeing what a difference SCSI over IDE has in a buildworld. --- Chris Piazza Abbotsford, BC, Canada cpiazza@home.net finger norn@norn.ca.eu.org for PGP key To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
