We had a similar problem that I was asked to resolve on our graphic stations.
We have Leading Edge model Ds [the 286 box] with EGA, Bernoulli removeable,
Everex 3mb board and an AT&T Targa-16 card under the hood.  Lot's of junk
fighting for the same address space.  We eventually got them all routed except
the Targa card DEMANDED that it run at A000:0000 (all other attempts failed)

My Solution:  Since our displays were Mono, and we had that *cute* little 
              utility called "EGA.COM"  I told our EGA it was a Mono display,
              and it moved its address space down to the B000:0000 area.
              Both cards are happy now (wish our users would be so 
              Cooperative :-] ).

My suggestion: If you can STAND being in CGA mode during the operation of the
               imager software, try this invocation batch file.

...
EGA CGA
(Execute imager)
EGA EGA
