In order to put the Fujitsu M2263E onto an MD21 ESDI disk controller,

you must have ROM rev A98E or higher. Contact Emulex, they have an

ROM upgrade program. You should also closely inspect your board rev

and have Sun upgrade it to the latest if your 3/160 is really old.

I have not verified that the board rev will actually keep it from

working, though, so this may be optional (I upgraded mine).

I actually have the 2263E working as sd0, with a second ESDI Micropolis

as sd1 on a SCSI-2 host adapter on a 3/160 running 4.1.1.

One other trick: when formatting, if you get errors while writing to

the last cylinder for the backup label using the MD21, WIPE THE GEOMETRY

from the disk by paritioning the disk and writing random data over sector 0

(at least). I always let it run for a few more sectors just in case.
