    Hiya all,

    Me again - the A+ novice ! Would someone mind checking the below for me to see if I have understood it properly ?

    To boot windows 9x/me need the files : IO.SYS + MSDOS.SYS+COMMAND.COM. Also need the himem.sys to load the GUI

    The registry is made up of two files : system.dat and user.dat

    To boot Windows NT,2000 and xp need the files : NTLDR + BOOT.INI + NTDETECT.COM + NTBOOTDD.SYS

    The MBR or MFT starts up NTLDR which then reads the BOOT.INI files to find where the operating system resides.

    NTDETECT.COM then detects the hardware installed and boots the system

    win.ini and system.ini are legacy 3.x files but dont really do anything now.

    Config.sys and autoexec.bat are ????????/

    Well Im a bit stuck on the last two.

    Any help really appreciated - youll go to silicon heaven :hug

    Martin

    How about I take a look at your last request.

    For a definition of config.sys, look here:

    http://www.webopedia.com/TERM/C/CONFIG_SYS.html

    For a definition of autoexec.bat, look here:

    http://www.webopedia.com/TERM/a/autoexec_bat.html

    Webopedia provides pretty understandable and bite sized definitions so hopefully those links will be clearer than some of the other stuff you'll find.

    The link below should provide some basic info about both config.sys and autoexec.bat.

    http://www.onecomputerguy.com/install/configsys.htm

    I'll let someone else tackle your other questions. I don't typically keep that kind of info on the tip of my tongue and would have to look it up. You might try using Google to check out your understanding to see if you can find some sources to confirm your understanding. Cheers. :)

    Hardy har har. :rolleyes: Nah, nobody gets paid here. It's all voluntary. That's one of the reasons I really admire SimonV for inventing the thing and Gav for riding herd on the whole project. We are just a community of like-minded folks who want to help each other out in the pursuit of a career in IT. Glad we can be of service.

    You only need NTBOOTDD.SYS when you need to boot from a SCSI device.

    Config.sys and Autoexec.bat are also legacy files but are also checked on startup. Anything in them is also then merged with the registry.
