[求助]要实现快速格式化并安装光盘下的win98，是不是这样写？
没有调用定位光驱盘符的子程序。
Autoexec.bat：
@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% （定位光驱盘符的子程序，重要）
set temp=c:\
set tmp=c:\
path=%RAMD%:\;a:\;%CDROM%:\
copy command.com %RAMD%:\ > NUL
set comspec=%RAMD%:\command.com
........
原98盘中的这个程序为：setramd.bat 内容如下：
@echo off
set RAMD=
set CDROM=
echo.
echo Preparing to start your computer.
echo This may take a few minutes. Please wait...
echo.
a:\findramd
if errorlevel 255 goto no_ramdrive
if not errorlevel 3 goto no_ramdrive
goto do_shift
:loop
if errorlevel %1 goto no_shift
:do_shift
set cdrom=%2
shift
shift
if not %1*==* goto loop
goto no_ramdrive
:no_shift
set ramd=%2
if "%RAMD%"=="C" goto c_drive
goto success
:c_drive
echo Windows 98 has detected that drive C does not contain a valid FAT or
echo FAT32 partition. There are several possible causes.
echo.
echo 1. The drive may need to be partitioned. To create a partition on the drive,
echo run FDISK from the MS-DOS command prompt.
echo.
echo 2. You may be using third-party disk-partitioning software. If you are using
echo this type of software, remove the Emergency Boot Disk and restart your
echo computer. Then, follow the on-screen instructions to start your computer from
echo a floppy disk.
echo .
echo 3. Some viruses also cause your drive C to not register. You can use a virus
echo scanning program to check your computer for viruses.
echo.
goto success
:no_ramdrive
echo The Windows 98 startup disk could not create a temporary drive for the
echo diagnostic tools. This may be because this computer has less than the
echo minimum required extended memory.
echo.
:success
