Yes, you can disable the internal floppy disk controller by monkeying
around with a PAL on the motherboard. I don't recall the exact chip
or location, but it was simply a matter of re-inserting the chip
with pin #1 bent out. I've never tried to do this, just picked it up
along my travels. Perhaps the hotline can offer you more assistance
on that matter.

I have had that happen with only two packages - Windows/386 and
Pagemaker. If you reboot with a clean system (no autoexec or config.sys)
I bet it fixes the problem. It did for me. I never did spend the time
to figure out what caused that to happen, but once I was able to
complete the installation, I really didn't care.

I got an installation guide when I upgraded the memory on my 6386.
It has what appears to be a linear algebra problem near the end of
the guide to help determine the proper switch settings for the
memory board. Another thing that may help you is a file posted on
the AT&T NSSC BBS (201-769-6397) called SIMMS.ZIP. It is a menu-driven
program, again, to help determine the proper switch settings.
Hope some of this helps, somehow...
