OK, I;ve looked and looked and can't seem to figure out how to set hw.ata.wc to enabled. I've put and a few other things in /etc/sysctl.conf, the others get set, hw.ata.wc doesn't. You can't change it by hand either as sysctl tells you it's readonly. Grepping in /sys/i386/conf has turned up nothing and neither has grepping /boot. No flames please, I feel I have tried to find the answer. :) Erick -- "Our vision is to speed up time, eventually eliminating it." -- Alex Schure To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
