遇到这样的IMG问题

tclshx

config.sys:
device=himem.sys /testmem:off
DEVICE=EMM386.EXE RAM
files=40
buffers=30
dos=high,umb
stacks=9,256
devicehigh=ramdrive.sys /E 8192
autoexec.bat:
@ECHO OFF
set EXPAND=YES
SET DIRCMD=/O:N
LH MOUSE.COM
LH TWAY32.EXE
LH PQMAGIC.EXE
遇行时总到最后显示:正在执行EMM386. 可用记忆限制为32MB.
然后一动鼠标就重启.为何? 若敲回车键,可进入PQ80中文版界面,动鼠标后又重启.怪也!
