This was an easy one. My original question was:

---------------

Help! I am trying to connect an Exabyte EXB-8500 to my Sun SS5. I have a hard
drive as SCSI device #2, but when I daisy chain the tape drive behind the hard
drive, the computer won't boot. It says "memory alignment error" right after
listing the boot device.

Any thoughts as to what might cause this (bad cable? too long a cable [mine is
five feet between tape drive and hard drive, one foot between hard drive and
computer]? something else?) would be much appreciated.

----------------

I received a variety of interesting responses. In my case, the solution
was simply to put a terminator on the second SCSI device (the tape drive). The
hard drive by itself worked without a terminator, so I assumed that the tape
drive would work without a terminator. This turned out to be an incorrect
assumption.

Many thanks to the following people for their prompt responses:
[And apologies to anyone who I accidentally left out.]
