Hello,
    I'm a beginner to the sun world, and apparently it's showing. I'm =
attempting to set up the SCSI bays on my 4/470, and I'm simply puzzled =
by what's going on.

I have an IBM 0664-N1H 2 gig 68 pin SCSI-W hard drive using an adapter =
to get the 50 pin SCSI1. I'm also using, alternately a sony 1x 8012 =
CD-ROM, which came with the system, and a Sony 4x CDU415, a drive that's =
been workable with macintosh machines in the past.

regardless of the configuration,
b sd(,30,)
gets me
sd: SCSI device not found

Now, both CD-ROM drives are set to ID6, which makes the calculated =
number correct. I've tried both drives, same results, with and without =
parity enabled. I've also gotten the same results with two different =
cables, with and without a passive terminator on either the drive, the =
CD-ROM, or a conector past the bus, and in both drive bays.

the command
b sd(0,0,0)
gets
no image found, attempting boot anyway
sd: scsi deive not found

for the hard drive, set to ID 0 (I know i need to move that to ID3).

entering the extended diagnostics via "x" and running SCSI path =
diagnostics gains me the same SCSI error, SCSI device path not found =
error1.=20

This machine has the following cards in it, and appears to be =
functioning normally other than this, and I'm accessing using a serial =
terminal (compaq laptop/kermit/null modem) on ttya.

(x2) 501-1333 32MB ECC memory boards
501-1381 0Mb sparc CPU
501-1855 IPI-2 controller
501-1217 sun-3 SCSI host adapter

If it's important, I can provide the spacing/slot assignment of all the =
boards and any jumper settings you request, but I am away from the =
machine at the moment so i don't have those handy.

One last question about the 470's drive bays; they appear to be a =
hot-swap type design that use a connector in the back of the bay. Inside =
the bay, there are a bank of 4 standard power connectors and 2 50 pin =
SCSI internal connectors. When the bay was removed after I got the =
machine, the cable used was looped around to where one end of the cable =
plugged into one SCSI connector and the other plugged into the second =
one, with devices in-between and unterminated. Is one of the connectors =
a terminator? I have no documentation whatsoever for these machines, and =
I'm winging it as to the manner in which they are set up....and I'm =
really puzzled by the layout on the drive bays.

Thank you,
Mike Free
