DEVICE--Notes Using standard device drivers The standard installable device drivers provided with MS-DOS are , , , , , , , , , , , and . The files COUNTRY.SYS and KEYBOARD.SYS are not device drivers. They are data files for the COUNTRY and KEYB commands, respectively. Do not try to load either of these files with the DEVICE command. If you do, your system halts, and you cannot restart MS-DOS. For information about loading COUNTRY.SYS, see the command. For information about loading KEYBOARD.SYS, see the command. Installing device drivers for other products When you purchase a mouse, a scanner, or a similar product, the manufacturer usually includes device-driver software. To install a device driver, specify its location and name on a DEVICE command line. Installing a third-party console driver If you install both DISPLAY.SYS and a third-party console driver, such as VT52.SYS, the third-party device driver must be installed first. Otherwise, the third-party device driver may disable DISPLAY.SYS. Installing multiple device drivers Sometimes one installable device driver will require that it be loaded before or after another in your CONFIG.SYS file. For example, EMM386.EXE requires HIMEM.SYS to be loaded first. If the device driver requires that another device driver be loaded before it, make sure the commands are listed in the correct order in your CONFIG.SYS file.
