WinXP msdos.sys and io.sys

The Windows XP includes autoexec.bat, config.sys,  msdos.sys and io.sys files, but they are all 0 kb in lengths. Since WinXP claims no DOS inside anymore,
why does WinXP still need these files?

Thanks in advance

itsun, they are used for emulation and compatibility issues.

Thanks. I have a further question:

I add some commands to \autoexec.bat, then I
open a DOS box, it seemed that autoexec.bat was
not executed. When will autoexec.bat take effects?
Thanks

Did you reboot after entering the lines in the batch file?

Yes I did what you said. My procedures:

1. I logged in as an admin.
2. Added "copy \config.sys \config.bak" commands to \autoexec.bat.
3. Reboot WinXP system.
4. logged in and open a DOS box
5. check \config.bak, and found none.

Seems autoexec.bat is useless.

Have you setup any apps that require this emulation? I presumed you had when I mentioned the reboot above. If there are not apps that require it, XP won't go through the setup, and I doubt you'll get the wizard to run without an app to point to.

DOS programs in default uses \windows\system32\autoexec.nt file, so I redirected it to \autoexec.bat, it worked..
Thanks
