)Simple.  Your boot disk should have a jumper on it set to the "master"

)position.  They might not be marked as such.  Consult your drive's

)Don't assume that your old drive is already a "master" drive.  Some
)drives have a third jumper position for "stand-alone" operation.  Your
)new drive will almost certainly NOT be in the slave position.

I believe the jumper configuration is stranger than that.  According to
the docs I got from seagate (they're from the BBS, hard to read, but I
think I got them right), the master drive should have master+slave jumpers,
and the slave drive should have *no* jumpers.  [Interpretation guide -
the thing that looks like a D is really a _, and the thing that looks like
a 3 is really a |.]  I.e. master has 3-4 short AND 5-6 short, slave
has no short, 1 drive has 3-4 short only.

Anyway, it worked for me.

PS - I think it's totally disgusting that the drives do not ship with
this doc, and the newer drive (a 3144A) didn't even have the labels on
the motherboard the way the 1144a I had did.  Very poor policy, IMO.

Check out the 'remote LED jumper' on the *DRIVE* as above.  (That was my
problem).  [May need another jumper as well on the controller, but you
also need to set a jumper on the *drive*.).  9-10 on the segate model I 
have.
