please refer to section V ("4") of http://fdos.org/ripcord/beta9rc5/readme.txt
summary:
MSDOS uses HIMEM.SYS.
FreeDOS had a range of drivers which do the same work:
*FDXMS286 : driver which works on 286 and newer, up to 16MB (286), 64MB (386 or newer)
*FDXMS : driver which works on 386 and newer, up to 64MB
*FDXXMS : driver which works on 386 and newer, up to 4096MB (I think, at least 64+
MB)
*HIMEM.EXE: driver which works on 386 and newer, up to 4096MB (I think, at least 64+
MB).
only 1 driver is compatible with EMM386: HIMEM.EXE
It's the preferred XMS-driver. Here's an example:
12?DEVICE=C:\FDOS\BIN\HIMEM.EXE
2?DEVICE=C:\FDOS\BIN\EMM386.EXE X=TEST
2?DOS=HIGH,UMB
the X=TEST statement is very strict in which UMB blocks it allows you to use,
and requires a newer version of EMM386 (see below).
I tried many combination of EMM386.exe
I got still:

I found no way with EMM386.exe
Aborting
incompatibility between FDXMS and EMM386, I guess.
There's also a newer EMM386 and HIMEM versions available than those with Beta9 release
candidate 5.
See ftp://ftp.devoresoftware.com/downloads/ for HIMEM and EMM386
Is FreeDos supporting 1024MB Ram I didn't found Infos about what FreeDos
is supporting?
Yes, I have a 1024MB equipped machine. (AMD Duron1200Mhz, 1024MB, lots of storage)
use HIMEM.EXE , and also EMM386 if you want/need it.
any idea
