However, when I issue the command (as root): sysctl -w hw.atamodes=---,pio,pio,---,---,--- Nothing is changed. No errors are issued, sysctl simply tells me that it's changing from ---,pio,dma,---,---,--- to ---,pio,dma,---,---,--- which is obviously not what I wanted to do. Anyone have any advice, hints on what's going on here? This is a promise ata100 controller and the system is currently running FreeBSD 4.2-RELEASE. (it's the same system I referenced in previous posts regarding HDD problems) Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
