The solution is to use the minix "fdisk" program, not the ms-dos "fdisk" 
program to set the partitions.  The source code for fdisk is on the 
commands disk in the ibmpc version 1.2 of minix.  I'd like to thank David
Lawyer and Robert Regn for sending me email to point this out.

Be CAREFUL!  I managed to render my DOS partition unbootable by using
Minix fdisk.  I was never able to figure out quite why, either.

Fortunately I had backed up both my DOS and Minix partitions before
I ran fdisk, since nothing short of a high-level format rendered my
DOS partition bootable again.  Of course, I'm hardly a DOSaphile, so
I might have missed something.  (Alas, I still have to run DOS for
some things.)

I wound up using a DOS-based disk manager program (not FDISK) to
repartition.  I would have saved several hours if I had done that
first...

Back up *everything*!!!
