Hm, DR DOS EMM386 should support any kind of machine, even if it's not
100% compatible. If there's an incompatibility somewhere it's good to 
know about it. 
I don't know if I can help, but I'd like to go into this a little, 
as it is quite well defined how to detect ROMs.
If you send a private email with your configuration files, MEM /A 
outputs, exact version numbers of DR DOS issue, memory manager, 
ROM-BIOS, and a memory dump from A000h..FFF0h (of course without 
any memory manager loaded ;-), and anything else that might help, 
I will have a look.

One thing to try: Load MS-DOS HIMEM before loading DR DOS EMM386.EXE.
(This will give a warning, because it's a sub-optimal configuration, 
but I'd like to know if this fixes your problem). The MS HIMEM.SYS
driver probably uses different detection methods for non-standard 
hardware then the DR DOS memory managers.
