Does the floppy drive LED light up during startup? It should, whether or
not the HDD works, and you should be able to boot from a floppy, even with
a dead HDD. Therefore if a boot disk doesn't work, either your floppy
system is defunct or it's in the motherboard.

An easy fix -- which doesn't always work -- is to disconnect and replace
all cables. It's fairly easy -- pull cables one end at a time *only*, so
you don't forget where they went.

Each device has 2 things going into it...a flat (usually, grey, sometimes
blue) ribbon cable, for the data; and a power cable. Both are keyed, so you
can't put them in backwards.

Trace the data cable from the floppy(ies) back to the controller card, and
pull & replace. Those are usually pins, and *can* be replaced backwards, so
take care. You can swap the controller card into another slot -- any slot
should work. If all slots are filled, exchange two cards.

Chips work their way out of their sockets ("chip creep"); push every
socketed chip back in.

I have boxes of cables, controller cards and drives if you need any; e-mail
me.

If the floppy disk does its thing, are you sure the floppy itself is OK? It
must be low density (you can tell by the hub ring) and have the proper
files; try booting another machine with it. Not all DOS's will work on all
machines -- I've even seen some older machines that won 't boot under DOS
