last I remember IDE spec automatically slows the bus to the lowest common demoninator(same for SCSI, but SCSI devices can take themselves off the chain when they are not in use). so it's possible that your CD-writer is not DMA/66 so the driver drops the bus to 33. also possible that your cable isn't up to spec. is your cable 18" or less? and are you using a 80-wire/40-pin cable? Some places offer 24" or even 32" IDE cables, which work on some systems but I prefer to stick to 18" wherever possible since that is the IDE spec(and I have had some problems with 24" cables hooked to promise IDE controllers - got some CRC errors on transfers, not fatal but I don't like seeing errors) nate (not a freebsd-head yet, but workin on it) To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
