China DOS Union

Hello everyone:
This afternoon I made an MSDOS boot disk and added UCDOS and DOSLFN. It boots normally, but it cannot display Chinese long filenames completely. I don't know what the reason is. Please help answer. This is the AUTOEXEEC。BAT file I wrote


@ECHO OFF
set EXPAND=YES
SET DIRCMD=/O:N
set temp=d:\
set tmp=d:\
set cdrom=z

path=a:\;%cdrom%:\;;z:\;z:\ucdos\

LH MSCDEX.EXE /D:mscd001 /L:z
LH DOSLFN /C- /Z:CP936UNI.TBL

call z:\ucdos\ucdos.bat
cls






Thanks
