: Ah, following up my own post. Well, I tried everything below and it worked thus
: far. The 735 booted fine once the 715 drive was connected and appeared to be
: identically configured. I then returned the 715 drive and hooked an 800meg scsi
: drive (quantum trailblazer) to the 715. I formatted the trailblazer using sam
: (adding 64 meg of swap), copied the contents of the 715 boot disk to it, and
: then ran mkswap on the /dev/rdsk/trailblazer_disk. After that I could boot the
: 715 from the trailblazer. I removed the trailblazer from fstab, rebooted, and
: the 715 appears good as before.
: I then moved the trailblazer to the 735 and booted it. Voila, system works fine.
: Now, my last problem getting the 735 working properly: It has two 1.2gig scsi
: drives internally on the fast-wide bus. I have the proper fast wide cable and
: everything is hooked up correctly as far as I can tell. Sam recognizes these two
: scsi drives, but when I try to format them, it says they have 0 megs. I tried
: formatting them outside of sam using mediainit /dev/rdsk/trailblazer_id and it
: starts up, initializes scsi, locks scsi, but then has an "I/O error". It does
: this for both drives.
: The only thing improper about the setup is that I do *not* have a scsi
: fast-wide terminator on the bus. Didn't buy it b/c I'm trying to do this on the
: cheap. Would lack of a terminal generate this kind of error? I'm used to other
: system with scsi II busses and so long as the cable isn't too long I could live
: without the terminator. I assumed that scsi III was the same, but I really don't
: know. I'm uncertain about the quality of these drives, if they're dead, etc.
: They do, however appear to spin up. Any advice would be appreciated. I'll
: probably head out and buy the terminator sooner or later, but I'd like to hear
: any opinions first. Thanks.

HP uses two types of Fast Wide interfaces, Differental and Single Ended.
I would assume that the 735 uses the Differental type of interface as
I do not believe HP switch to the Single Ended until the C class work
But to answer you question, Yes you need the a terminator at both end of
the scsi chain. This is the most likely reason you system did not boot
in the first place.
I would use IOSCAN to see if the drive are visible from the system or
one of the diagnostic. I believe that the boot rom will allow you
scan all scsi interface looking for a bootable device.
Hope this helps,
(Waiting for my HP712 to finish it startup processing.)
