thx alot for ur help Guardian
it was alot useful
i have removed those 2 lines and it worked
but there is an error message that appear when i boot using that boot disk and it says :
WARNING :
The high memory area (HMA) is not avilable.
Additional low memory (below 640K) will be used instead.

but it worked well.
any way i was asking how 2 remove those lines for :
a- Partition magic prog which run under dos was complaning about the high memory.
b- There is another prog wich manpulate partitions was complaning and wasnt runing .

now i want to ask for some further q's
at first is the himem and emm386 useful or not.
is that increasing speed of any thing or what ?
do u think the removnig if those lines could affect any thing ?

here is a copy of the modified config.sys :

DEVICE=OAKCDROM.SYS /D:MSCD001
FILES=20
BUFFERS=20
DOS=HIGH,UMB
STACKS=9,256
and here is a copy of the autoexec.bat
@ECHO OFF
PROMPT=$P$G
PATH=A:\
SET DIRCMD=/OGNES
LH MSCDEX.EXE /D:MSCD001 /L:X
LH DOSKEY /INS
LH SMARTDRV
