We will be receiving a SC780 and a Fujitsu Eagle shortly, with the
ultimate plan being to run 4.2bsd on the 780. We presently run 4.1bsd
with two RP06's which will remain on the system when we convert to
4.2. There will be a short time during which we will have the Eagle
[hopefully] running under 4.1, which prompts my questions.
1) While the hp.c in 4.2 has a table, etc., for the Eagle,
4.1 does not. Thus, it would appear that if I am to run
the drive with 4.1 I must get the B2 firmware for the SC780
unless I want to hack hp.c. Is this true? (The B2 firmware
supports 44 sectors per track and wastefully emulates two
RP06's).
2) If the answer to 1) is yes, does anyone have a hacked hp.c
that works with the B3 firmware? If so I'd appreciate a
set of diffs.
3) Is the B3 firmware the way to go with 4.2bsd? It would seem
so since it handles 48 sector tracks and allows 414 Mbytes
of storage; also, the table in hp.c appears to be set up with
this emulation (extended RM80) in mind.
Thank you.

I don't think you have to get the B2 firmware. Our SC780 (apparently
with B3 software---nobody mentioned anything about revisions) was
settable to any of a bunch of emulations. But by all means, hack
hp.c for 48 sectors/track.
2) If the answer to 1) is yes, does anyone have a hacked
hp.c that works with the B3 firmware? If so I'd

Sure. (``It's in the mail'' --sorry)

I would say so. It only took a few minutes to put in tables for
the ``RM02'' 48 spt drive. It took about an hour to hack up config,
hp.c, and dkbad.c to support both NOBADSECT *and* bad sector
forwarding simultaneously; we didn't want to lose the extra space
off our RP06s just to be able to run the Emulex, so we run both
instead.
[Note: we're still running 4.1. I haven't looked at the 4.2 hp.c.]
