 Normal MFM controllers never come with an own BIOS, so there's nothing to
 jump to. 
  XT controllers do.  But now I recall that Ian said "WD1003" and I seem
to recall that that's the AT controller series.  I think I remember
using an "IBM Advancced Diagnostics" floppy, or something like that, for
this.
