First, you don't say what operating system you are using.
If you don't have ports in Win9x, you should try adding new
hardware wizard to see if any are detected. A 486 is not likely
to be plug and play.

If you don't have ports listed when the bios displays a summary
of installed options in text format, usually in linedraw boxes
just before the boot process completes, you have a cmos setup
or jumper block problem.  Since a dx66 is unlikely to have on
board IDE and communication ports, you likely have an expansion
adapter, probably an integrated floppy, fixed disk, serial, and
printer port card.  The jumpers would be located on this card.
If you don't have the documentation, you are going to have trouble
locating the right jumpers.

I have Mitsubishi Apricot 'XEN-PC' 486DX66 which I am setting up and
have run into a problem:

Both MSD.EXE and another diagnostic report no COM ports despite the
physical presence of two, clearly labelled as such.

Could these have been jumpered off for some obscure reason, or am I
looking at a board failure?  Any advice on restoring these ports much
appreciated.
