    starting computer under DOS mode?

    I know I can start a computer using a DOS boot disk. But is there an alternate way to load up DOS without a boot disk and before Windows loads up (including the F8 key option)?
    think only with code.
    write only with source.

    uhh...

    Correct me if im wrong... but unless u have a really old OS, you cant. In the newer windows you still have the "command prompt".

    Go make a "Hello World" prog, then hit ctrl+alt+del.
    Scroll down the list and you'll see winoldapp.
    lol.
    What is C++?

    DOS is actually loaded before your windows during booting. (dont know about XP)

    Yes but you're in a DOS environment before XP boots.
    You can access the command prompt be either using a '98 bootdisk or a DOS bootdisk..

    you aren't in a dos environment when xp or 2000 boots up...

    when you use a boot disk the command.com is loaded then you are inside dos, XP&2000 do not have dos. Windows 98 was built on top of dos 7.0, XP & 2000 does not rely on dos...

    okay, if I have Win98SE, Win2000Pro, and RedHat (starts under Win98SE) and I only want to load up the computer under DOS and keep it that way, what do I need to do? Do I need to make a copy of command.com on "C:\" in my main hard drive and do something? Is there a way to ignore the Windows boot up sequence and stick with DOS? I appreciate the help.

    you could press ctrl-c many times during the boot sequence until you get a "Terminate batch..." message, press y, then you're in dos.

    They took the "Restart in MSDOS mode" option off the shut down list for a reason...

    He wants it during bootup.

    >>Do I need to make a copy of command.com on "C:\"...
    i think you already have it there.

    you could put the line "command" in the end of autoexec.bat and then see what happens during bootup.

    PS if something wrong/weird/evil happens dont blame me.
    just wait for some more suggestions.

    I am assuming that win2000 is automatically started, ( I don't have win2k here so I can't confirm if this is exactly how it goes)

    right click on My Computer, goto properties, goto advanced, change the boot sequence to have win98 start up first.

    once you have booted up into win98 now you can use one of the options the other people supplied or edit your config.sys / autoexec.bat to contain a menu. to do that just do a search on google for "config.sys menu" or something like that...

    well, I've tried adding "C:\command.com" in front of the other application directories and it works. however, doesn't this mean that Win98SE (starts under Win98SE) is loaded in some way since Win98 relies on this instructional boot sequence file to load up. autoexec is used by Win9x, I believe.
    so this is like loading MS-DOS under Win98SE before win.com loads up.

    if only I knew how Windows works as to how it initializes...
    anyway, do I need knowledge in OS programming (since OS programming requires knowledge on booting up the OS upon starting the computer)?

    To start DOS, during boot-up sequence prss F8 and then select
    DOS PROMPT ONLY
    (this option may not be available in WINme and earlier ver.)
    cuz STUPID MS took DOS out.

    If you want it to happen automatically everytime, you could just edit your autoexec.bat file to not start up windows, but that'll only work for OSs before the current style (like 95 graphics)
