Yes, but none of them is compatible with M$-DOG. If you want to have just one
set of conf*.sys aut*.bat files, then you have to use a third party
multi-config util - OpenDOS will refuse to load properly from the M$-DOG
multi-part config.sys. Of course, you could use the CHAIN statement at the
beginning of the M$-DOG multi-part config and load the OpenDOS one with
SELECT statements.

GRUB works perfect.

Ah! Didn't know that - that's the solution I was looking for! Thanks, so far
I used the autocon package (from simtel in msdos/bootutl)

Also you can freely use the SELECT statement in that file - neat! But
there's a small problem with installers modifying the startup files - they
will do their job only on the 'standard' ones.

And you can share the autoexec.bat between M$-DOG and OpenDOS by simply
setting CONFIG in DCONFIG.SYS to the current configuration name, just as
M$-DOG does in behind the scenes. Or even do 'goto %OS%' - if there's no OS
set, it will do nothing and process the M$-DOG part, if OS is set - you move
to the OD part. Neat(2)!

So far, I the best result I got was 622K... ;-(

Midnight sun bids moors farewell, retreats from charging dusk,
Mountains echo, curfews bell, signal ending tasks.
They place their faith in oaken doors, cover in candle light
The panic seeps through bloodstained floors
