We will be receiving a SC780 and a Fujitsu Eagle shortly,
...
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).
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
appreciate a set of diffs.
Sure. (``It's in the mail'' --sorry)
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.
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.]
