Well, I stumbled across the answer myself.  Thanks for all of the
responses, but the correct answer is the following:

The disk is formatted with the first partition as DOS and the
second as UNIX.  If you are running UNIX and wish to change
the active partition, you MUST use the UNIX FDISK.  If you are
using DOS and wish to change the active partition, you MUST use
the DOS FDISK.

I had been running under UNIX and I placed an MS-DOS boot disk
in drive A and reset the machine.  After is booted, I used
the DOS FDISK to change the active partition.

Oh well. . . I didn't know any better at the time.--
