CONFIG.SYS

   Also found in: Wikipedia 0.02 sec.
CONFIG.SYS
A DOS and OS/2 configuration file. It resided in the root directory and was used to load drivers and change settings at startup. Install programs often modified CONFIG.SYS in order to customize the computer for their particular use. Windows 95/98 executed the lines in CONFIG.SYS if it contained drivers that it found no counterpart for when it was installed. See DOS CONFIG.SYS.
