The 2249 is not viable on the 3130's ESDI controller.  The only 380 MB
drive that is qualified to run on the 3130 is a semi-custom version of
the Micropolis 1558-15.

It is a 380 MB drive.

1243 cylinders, 15 heads, 34 sectors/trk.  Gaps should be set to 0x19,
0x13 and 0x26.  It will run best at a 2:1 interleave, but not reliably
at all.

The jumpers are for address and bytes/sector.  Some others are factory set
and should not be tampered with.  You should be able to get specifics from
Fujitsu Americas Support organization (jumper locations often change when
drive is rev'd) at (408)432-1300.
