How cheap.... [ML] Not necessarily. Might be a 3.0R sync negotiation bug, because I get the same rate for IBM DCASmumble hard disk hung off an aha1542CF. The disc and the card are fast SCSI devices, 10 MB/s should be possible (okay, I don't care much because ISA cannot trasfer more than 2-3 MB/s anyway :) /Marino To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
