But i have just one single question: He >can i force wide occur ? I missed out on some of this thread, so please forgive me if I'm repeating something that was said... If I recall, you said you had an Adaptec 2940UW... if that's the case, when you first power up the computer, it should show you the BIOS checks of the CPU and RAM, and should (hopefully) off you an option to "Press CTRL-A To Enter SCSI-Select Utility", or a very very similar statement. If you press CTRL-A at this prompt, it will take you into the Adaptec BIOS. In there, you can configure device options, and set "wide" negotiation on and off for each SCSI ID. If you know your SCSI ID # for the Wide drives (which was in your dmesg output, which I no longer have), you can set that drive to negotiate a wide connection. If the connection doesn't go wide at your next boot up, then you have problems which I've never known how to fix, other than replacing the drive =) Good luck, John To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
