*DING* Unibus addressing - KZQSA SCSI adapter

You DEC old-timers out there will probably chuckle at my little "discovery", but I'm posting my findings for us who are "DEC challenged".... Yesterday I was pulling my hair out trying to get my VAX 4000-500 to recognize an external RRD-43 CD-ROM that was attached to a KZQSA SCSI adapter. No matter what I did, it wouldn't recognize the fact that anything SCSI was connected. The problem turned out to be the address that the KZQSA was set to. It was set to address 761400, and the 4000 was reporting the card to be a DEFQA, which to even a DEC newbie as myself, was VERY wrong. A search through the "VMS wizard" archives at Compaq.com turned up the statement that the KZQSA was shipped with a default address of 761300. So I fiddled with the address jumpers and set it to 761300 and *voila*, the 4000 found the KZQSA. I hooked the external SCSI enclosure to the card, and it found the CD-ROM. It was able to boot VMS from the CD, and I'm on my way. Again, don't laugh too hard, I hope this message helps others who are "Unibus Ignorant".... - Matt Matthew Sell Programmer On Time Support, Inc. www.ontimesupport.com (281) 296-6066 Join the Metrology Software discussion group METLIST! http://www.ontimesupport.com/cgi-bin/mojo/mojo.cgi "One World, One Web, One Program" - Microsoft Promotional Ad "Ein Volk, Ein Reich, Ein Fuhrer" - Adolf Hitler Many thanks for this tagline to a fellow RGVAC'er...
