As you are assuming right later, I do mean PC DOS 7 HIMEM.SYS running under 
DR-DOS.

even done the first one (ver 6.22) - as supposed its the same  :-)

Hmm, hardly to believe. AFAIK they didn´t include any chipset since DR DOS 6. 
;-)
How CHIPSET should know about today...

ok, did it now as well - of course no success, best I got was:
 _specified chipset not or no shadow RAM_

and now DR-DOS 7.03 with

regardless of the drivers or switches (believe me! :-), I tried this also in

one DOS is profen being better) results in:

anything strange?
but don´t no how to deal with
anyway it happens on my notebook (later) as well as on my infamous P60 
(Batman revange).

P166MMX Step 4    :-(
Chipset made by UMC: UM8891N (Notebook), UM8886N EIDE/ISA bridge

Maybe the other way round. :-))
If anyone out there could provide me any good info/datasheet/pointer 
about that particular chipset (programming) really I would be happy 
to spent that time... ;-)

At least I would do it before HIMEM.SYS and then provide RAM with the
 CHIPSET=RAM USE=... switch
So I do on the other machine.
I know being responsible for what I´m doing there ;-) (esp. DMA transfer etc.)

btw - If I could run it that way - I would never ever thinking of using any 
other XMS driver than DR-DOS ! ;-)
