Low-level format the disk using DEBUG and the WD BIOS program at C800:5
(or their DOS formatter).

Boot UNIX "Disk 1 of 7."
Partition numero uno should be DOS, 80 cylinders (if my math is correct,
your Maxie yields 414,720 bytes per cylinder and 32M is 33,554,432
bytes.  Next partition (the active one) should get 1552 cylinders. 
Ignore FDISK's reporting of anything except starting cylinder number. 
Then, just continue with the installation.

???  I used "enabled" for a 1222 cylinder Maxie on a 1007-WA2.  Cope?

No need to.  No.

You mean if your DOS partition is formatted and sys'd and made active,
you still can't boot?  I'd start all over, doing what I suggested above.
