I have a DecStation 3100, running Ultrix 4.1 (recent upgrade) and it's crashing all over the place. Actually, it's been crashing for years, but now it's a problem. I have a "real cheap" SCSI drive on it (Newbury NDR5380) that doesn't support (very well) SCSI disconnect. So every now and then the system hangs when this bug is encountered. I'd turn the feature off on the drive if I could, but I have no idea how. Does anyone have any idea how to get the DecStation to not do SCSI disconnects anymore. Anyway to modify scsi_data.c or some other file, or some kernal configureation? Please help. woolstar@cobalt.caltech.edu

I also don't recommend trying to make our SCSI driver not use certain SCSI commands to cover a SCSI compliance problem. I don't know, but I'm hoping, that this could be fixed with a firmware modification. While I am not familiar with Newbury if they are willing to try and solve the problem you might have them get in touch with us in one of the following manners: 800.678.OPEN triadd@decwrl.dec.com 415.853.0155 FAX We'll do what we can to make sure the disk drive works on our DECstations. We'll be happy to help if we can. Thanx, AJ P.S. This isn't necessarily a "hopeless" or "long-term" problem. We recently were able to help a High volume third party disk drive supplier understand that their disk drive firmware wasn't providing an ID back after reset within a 2x factor of the ANSI specified time-out and they were able to provide a test version of new firmware in less than 10 days. ********************************************************************** * AJ Casamento "The question is not whether or * * Digital's TRI/ADD Program not they are my opinions; but * * 100 Hamilton Ave. UCO1-B rather, which of my personalities * * Palo Alto, CA 94301-1616 do they belong to? * * 415.853.6744 * * ajc@decwrl.dec.com * **********************************************************************
