是这样的：比如我的硬盘分区是两个区C盘和D盘，通常我们用WIN98启动引导系统到DOS带有光驱时，光驱会在第四个盘符也就是F盘，现在就是能不能修改下config.sys这个文件的内容，可以使启动到DOS后光驱保留，而把这个E盘去掉。
启动后光驱显示的盘符是E盘而不是F盘。
原来我的CONFIG.SYS这个文件内容如下：
device=himem.sys /testmem:off
device=oakcdrom.sys /D:mscd001
device=btdosm.sys
device=flashpt.sys
device=btcdrom.sys /D:mscd001
device=aspi2dos.sys
device=aspi8dos.sys
device=aspi4dos.sys
device=aspi8u2.sys
device=aspicd.sys /D:mscd001
files=10
buffers=10
dos=high,umb
stacks=9,256
devicehigh=ramdrive.sys /E 2048
lastdrive=z

对应的批处理是这样的：
@ECHO OFF
set EXPAND=YES
SET DIRCMD=/O:N
set LglDrv=27 * 26 Z 25 Y 24 X 23 W 22 V 21 U 20 T 19 S 18 R 17 Q 16 P 15
set LglDrv=%LglDrv% O 14 N 13 M 12 L 11 K 10 J 9 I 8 H 7 G 6 F 5 E 4 D 3 C

不知道可行不，高手帮帮忙！！

你去掉了F盘，那么在EBD.CAB的东东你是用不了的
