I tried that, and the 5.0.x driver still could not deal with the tape drives (unfortunately, I don't have the log output available, but I can redo it if necessary). I also tried disable scsi parity support, and it could not discern either the tape drive or cdrom at boot time. Right now, I'm running the machine with covers off, the Adaptec is between a TekRam 390F scsi controller, and an original Soundblaster 16 (non-pnp) sound card. -- Michael Meissner, Cygnus Solutions (Massachusetts office) 4th floor, 955 Massachusetts Avenue, Cambridge, MA 02139, USA meissner@cygnus.com, 617-354-5416 (office), 617-354-7161 (fax) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-aic7xxx" in the body of the message
