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 cls call setramd.bat %LglDrv% set temp=c:\ set tmp=c:\ path=%RAMD%:\;a:\;%CDROM%:\ copy command.com %RAMD%:\ > NUL set comspec=%RAMD%:\command.com copy extract.exe %RAMD%:\ > NUL copy readme.txt %RAMD%:\ > NUL :ERROR IF EXIST ebd.cab GOTO EXT echo Please insert Windows 98 Startup Disk 2 echo. pause GOTO ERROR :EXT %RAMD%:\extract /y /e /l %RAMD%: ebd.cab > NUL echo The diagnostic tools were successfully loaded to drive %RAMD%. echo.
