A fair amount of warining is in place though it _can_ cause problems, I'm not in any way making any garanties :) However some controller chips can tristate all outputs, and those should be safe for hotswapping, modulo eventual static charge problems... -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
