Dos 3.3 I believe has a slightly different master boot block from earlier DOS's
to deal with extented partitions. UNIX 286 must share that boot block with DOS
and so it has to know all about the boot block. V/AT's fdisk does not know
about the *new* extended partion stuff and so won't work with DOS 3.3 or 4.0.
The newest DOS you can use is 3.2.1. I'm really suprised that V/AT boots at all
with DOS 3.3 installed.

BTW,
This problem has nothing to do with DOS Merge.
