Probably even with a fairly long cable? Try using the DPT controller's BIOS utility to set the SCSI bus speed down from the default 20MHz. 10MHz should do it. The author of the DPT drivers posted a (long) message here some time ago relating to the problems various people are experiencing with these controllers. If you're interested, mail me personally and I'll forward you my saved copy of it. -- V Johann Visagie | Email: wjv@CityIP.co.za | Tel: +27 21 419-7878 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
