In reading though many of the posts in the last few months I found out
that large drive support has been added with certain caveats. I can't
change the configuration of the system that I need to make this work on.
Essentially, if I can make this work, I can deploy Linux in the Army on
approximately 50000 systems. It will definately get noticed.
The drive partition is approximately 2 GB (whatever the largest
partition size is for FAT16).
I finally got a config file that appears to work (mostly).
Here is a screen shot of system commander just starting up:

I cheated the cyl, heads, and spt. The real disk parameters are 527
cyl, 255 heads, and 63sectors. I changed it to the following so that it
was within the limitations of the BIOS and IDE. Again, even though the
disk is larger that 4GB, I only have the MSDOS partition (sda1) within
the limits of FAT16.
Here are the guts of the config file:
plugin = ./plugins/bochs/plugin-bochs.so
bochs-opt boot: c
bochs-opt diskc: file="/dev/sda", cyl=8959, heads=15, spt=63
bochs-opt floppya: 1_44="/dev/fd0", status=inserted
bochs-opt cdromd: dev="/dev/scd1", status=inserted
bochs-opt keyboard_serial_delay: 200
bochs-opt floppy_command_delay: 500
bochs-opt vga_update_interval: 200000
bochs-opt mouse: enabled=0
bochs-opt private_colormap: enabled=0
bochs-opt i440fxsupport: enabled=0
bochs-opt newharddrivesupport: enabled=1
bochs-opt ips: 1000000
bochs-init
Everything works great. Even my System Commander starts loading and I
can pick which OS to boot from. System Commander copies all the files
from the C:\SC directory to the C:\ directory (msdos.sys, io.sys,
command.com ..... all the files necessary for booting the selected OS).
Then I get the following and MSDOS 6.22 never boots:
