Thanks so much for your help.  After I updated the BIOS it works much
better.  I went back to the place I got the FreeDOS boot image and saw where
it warned against running old BIOS images.  Sorry I didn't see that.  Also
the ips=15000000 was causing it to run slow.  I assume that is instructions
per second.  I was able to boot and run the Menuet operating system.  It was
too slow to be usable, but it did work.  Here's my bochsrc.

romimage: file=$BXSHARE/BIOS-bochs-latest, address=0xf0000
vgaromimage: $BXSHARE/VGABIOS-elpin-2.40
megs: 32
floppya: 1_44="mos076.img", status=inserted
boot: a
log: out.bochs
mouse: enabled=0

I'm thinking about trying to install GEM next.  I wonder if anybody has
tried that.

Also, should I send a zip of this to somebody so they can put it on the list
of operating system images?

Assuming that you are using a recent version of Bochs, is there any
particular reason you are not using the BIOS and VGABIOS that came with it?
The versions you specify are so ancient that I don't think they are still
available for download. By "access a floppy" do you by any chance mean the
FORMAT command? That is known not to work under FreeDOS. You didn't say
whether you were running Bochs under Unix/Linux or Windows. 
Under Unix/Linux you can transfer stuff between virtual floppies and your
hard disk by mounting the virtual floppies using the loopback device. You
can use the real floppy drive under Windows by specifying 1_44="a:" or under
Unix/Linux by specifying its device file such as 1_44="/dev/fd0" or
1_44="[fd:]" under Mac OS9. I have booted FreeDOS under Bochs before and it
came up much faster than Linux, so I don't know why it takes longer than
Linux on your system.
