Lines: 41 * From: goldfarb@ucf-cs.UUCP 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.] -- In-Real-Life: Chris Torek, Univ of MD Comp Sci (301) 454-7690 UUCP: {seismo,allegra,brl-bmd}!umcp-cs!chris CSNet: chris@umcp-cs ARPA: chris@maryland
