没有用软件，用最老土的方法：
首先用瑞星软件做了6张瑞星的软盘将所有文件复在一个文件夹ravdos中
再做了张98启动盘，并改了AUTOEXEC.BAT和CONFIG.SYS两个文件
最后用Nero StartSmart刻录的（刻录别的启动盘一点问题没出过）
===========================================================================
AUTOEXEC.BAT是这样改的：
===========================================================================
@ECHO OFF

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:\

copy command.com %RAMD%:\ > NUL
set comspec=%RAMD%:\command.com

===========================================================================
又将CONFIG.SYS改了一下：
===========================================================================

用这个改过的win98启动软盘启动电脑情况良好，提示也多了这一项：with RAV support.
就是在开始刻录时总是出现暂存盘错误的提示，百试不爽 作者: gotomsdos 时间: 2005-3-9 23:17 标题: 制作瑞星2005DOS杀毒光盘时，出了点问题，有人能解乎？ 只要容量够,刻录跟文件内容没关系呀! 你这不走题了吗?
关键你要讲一下怎么作成ISO的,什么做光盘的引导文件,
这个暂存盘错,是不是临时文件夹容量不够了,还是刻录前的设置弄错了. 作者: lxcght 时间: 2005-3-10 11:58 标题: 制作瑞星2005DOS杀毒光盘时，出了点问题，有人能解乎？ 我用WIN98软盘做的文件引导，不用做成ISO吧，
临时文件夹容量我想没有问题吧，至于刻录前的设置，具体是指什么样的设置。我用同样的方法做WIN98启动光盘一点问题没出啊
