I don't have a list of all the jumper options for the sa455, but
here's something obvious to look for:

IBM used a ribbon cable with a "twist" for drive a.  Other
manufacturers used a straight-through cable.  If you have
the cable with the twist, then both drives should be set 
up to select the second drive (ie: ds1 if labelled ds0..3,
ds2 if labelled ds1..4).  Otherwise, the A drive should be
selected as d0, and the B drive as d1.

The drive at the end of the connector chain (drive A if you
have a standard IBM PC) must have a terminator resistor
package in place.
