Umm.. Not sure if it's much use, but:
1: I compiled doscmd with X11 support
2: DOS 5.00 in drive a:
pwroot@beast[9:56am]~peter/sys_privpages/compile/BEAST-164# mdir a:
Volume in drive A is BOOT
Volume Serial Number is 0000-0000
Directory for A:/
command com 47845 04-09-1991 5:00
sys com 13440 04-09-1991 5:00
fdisk exe 57224 04-09-1991 5:00
format com 32911 08-15-1991 23:22

chkdsk exe 16200 04-09-1991 5:00

3: more ~/.doscmdrc

assign A: /dev/rfd0.720 720
assign hard boot_drive 80 2 2
X11_FONT=8x16
4: Boot dos from a:
peter@beast[9:58am]~-160> doscmd -x -b
Init: 0
Unknown interrupt 15 function 4101
Unknown interrupt 15 function 87ee
[DOS 5.00 command.com prompt in an X11 window at this point, dir etc work]

I'm not sure if that's a problem with what I've done to get it to compile/
run under SMP, or whether it's something else. The src/usr.bin/doscmd/
README.* files have more detailed instructions on what order to do things
to boot from a virtual drive within a 'file'. How one would use a slice,
I'm not sure. Beware that the doscmd docs use BSD/OS pathnames for
devices.. ie: /dev/rfd0_1440_3.5 vs. /dev/rfd0.1440
I have not built a virtual hard drive for the dos box, that's unknown
territory to me.
The X11 code wants a "vga" X11 font. I changed it to something else to
get it to load..
BTW: src/usr.bin/doscmd/i386-pinsn.c is GPL'ed... :-O
