Strangely, 2 work. Also, Linux has some sort of hack for getting 3+ working. I'm also severly disappointed in Promise, their website has no mention whatsoever about this kind of limitation in their cards. It wasn't until I called their tech support that they told me they don't support it. Otherwise, this is mostly a despiration move. -- \ |_ _|__ __|_ \ __| Jason Andresen jandrese@mitre.org |\/ | | | / _| Network and Distributed Systems Engineer _| _|___| _| _|_\___| Office: 703-883-7755 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
