A text file containing special system configuration commands. It is found in the root directory on an MS-DOS computer, typically on drive C (the {hard disk}). It is read by {MS-DOS} at {boot time}, after the setup has been read from CMOS RAM and before running AUTOEXEC.BAT. It can be modified by the user. Some example commands which CONFIG.SYS might contain are: DEVICE=C:DOSHIMEM.SYS /testmem:off Load the extended memory manager. DEVICE=C:DOSEMM386.EXE RAM Load the expanded memory manager. BUFFERS=10,0 Specify memory for disk buffers. FILES=70 Set the number of files that can be open at once. DOS=UMB DOS is located in UppeMemoryBlock. LASTDRIVE=Z Disk drives are A: to Z:. FCBS=16,0 Set the number of file control blocks. DEVICEHIGH /L:1,12048 =C:DOSSETVER.EXE Report the DOS version to older programs. DOS=HIGH DOS should maintain a link to UMB. COUNTRY=358,437 C:DOSCOUNTRY.SYS Set the country code for some programs. STACKS=9,256 Set dynamic stacks for hardware control. SHELL=C:DOSCOMMAND.COM C:DOS /E:1024 /p Set the location of the command interpreter. (1995-03-16)
