If it's also saying something about dropping to PIO mode then... I keep thinking this one ought to make the FAQ (if it hasn't already) as, depending on the phrasing of search words, there's often about 2,000 hits on deja with it. 9 times out of ten (two machines out of two in my case) it can be fixed by simply replacing your IDE cable with shielded 80 pin ATA 100 IDE cable. (Which can be found for around 3-6 dollars). I thought that it was only FreeBSD that was so sensitive to it, but closer looking at various Linux bootup dmesg showed that it was affecting Linux as well. >HTH Scott Robbins To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
