In the installation documentation for the DECStation 3100 (YES! I read it!) it IMPLIES that you can place any of the peripherals (disk, tape, optical disk, etc) on any of the 6 port addresses that are available. Doing a "test -c" at the prom prompt will list what devices are on what ports. You then use this information during the installation process. However, if you have the TZK50 (tape cartridge) on any port other than port 5, when you attempt to boot, you are informed that the device on that port is busy. If you install the tape on port 5, it will boot properly. Is this an error on my part, was there a part of the documentation that I missed, or is the boot prom looking for the tape drive to ONLY be on port 5?

------- Might be a bug in the prom microcode for the DS3100. I tried it on my machine and it acted similarly. I do know that I had a TK50 at a different unit than 5 for testing purposes and that worked but I don't recall ever trying the boot code path with the tape unit at a different than 5 value. I don't believe it has anything to do with the SCSI implementation. It's most likely a prom bug. --- Ricky Palmer Ultrix Advanced Development --- Digital Equipment Corporation --- Nashua, New Hampshire --- ... One of the fathers of PMAX ...

Ricky, I have been booting my TK50 (ugh!) from SCSI target 1. No problems. aps.
