Can anybody refresh my memory as to the correct commands to write a batch file which asks for a password in DOS, ie. BEFORE Windows starts up thus locking the whole system and/or add it to the AUTOEXEC. My DOS editing skills, which were nt famous to start with have withered since Windows 95! Also, secondary, would this work with the new Windows XP to which this computer is to be upgraded. Thnx for the help!
