私立医院分诊护士退休:为什么我的机子中的MSDOS.SYS文件显示是0KB,用文本编辑器打开是空的啊!怎么才能打开它啊

这个文件是原来DOS系统和98系统的启动配置文件，在2000或XP系统没什么作用，可以删除的。以下是95或98系统的此文件内容：
[Paths]
WinDir=C:\WINDOWS
WinBootDir=C:\WINDOWS
HostWinBootDrv=C

[Options]
Logo=0 ;显示WIN95标志
BootMulti=1 ;允许多引导功能(F4或F8)
BootMenu=0 ;=1时自动显示启动菜单
BootMenudelay=00 ;设置启动菜单停留时间
Bootmenu Default=01 ;设置缺省引导菜单选项
BootGUI=1
Network=1

;BootWin =0时引导旧版本DOS
;Bootkeys =0使键无效，如F4和F8
;BootDelay =n设置按引导键时的间隔值，默认为2秒
;Logo 使图形徽标无效
;DrvSpace 使压缩无效
;DblSpace 使压缩无效
;DoubleBuffer =0使SCSI设备的双缓冲区无效
;BootFailSafe =0使启动菜单中安全方式失效
;BootWarn =0使安全方式中的警告消息无效
;BootTop =0强制驱动程序加在常规内存的底端

;The following lines are required for compatibility with other programs.
;Do not remove them (MSDOS.SYS needs to be >1024 bytes).
