- Press H to view AUTOEXEC.BAT
- CONFIG.SYS - Operating System Configuration file
- AUTOEXEC.BAT - Automatic Execution Command List file
-
- The SYSTEM HARDWARE display keeps you from having to open up your system
- box to find out the number and type of PORTS, system memory, disk
- devices & capacity, etc.
-
- AUTOEXEC.BAT is a file which holds a list of commands the PC will do at
- power-on (boot-up). These commands will run just as though you had
- typed them at the C> DOS prompt.
- To use alternate AUTOEXEC.* and CONFIG.* files, and/or to re-boot your
- PC from a menu, refer to EasyMenu documentation.
-
- CONFIG.SYS does 2 things: 1. Assigns memory for DISK ACCESS.
- 2. Assigns memory for DEVICE DRIVERS.
- Default Min Max Norm
- 1. DISK ACCESS BUFFERS = 2 1 99 20
- FILES = 8 5 99 20
-
- Each file over 8 costs 39 bytes of memory. FILES=20 costs .5 K
- Each buffer over 2 costs 528 bytes. BUFFERS=20 costs 9.5 K
-
- NOTE: Screen, Keyboard, Printer, Aux, & Error = 5 FILES already!
- SYSTEM PERFORMANCE
- Your programs will run slower if BUFFERS is low, and some programs may
- require a FILES statement of 15 or higher. When running a hard disk or
- on a Local Area Network, FILES should be at least 15.
-
- To see the effect on performance, set BUFFERS = 2, reboot your system
- and run some programs. Then set BUFFERS = 20, reboot and run the same
- programs; you should note a dramatic difference.
- 2. DEVICE DRIVERS DEVICE=\device#1 file name
- DEVICE=\device#2 file name
- DEVICE=\device#x file name
-
- Device drivers allow control & communication with external hardware such
- as robots and video disk players; others enhance the operation of your
- PC. DOS 2.0 allows for 256 device drivers, of which DOS reserves 64.
-
- DEVICE = ANSI.SYS Screen enhancer | Sample CONFIG.SYS |
- DEVICE = LDP1000.VAL Video disk player |-----------------------|
- DEVICE = MDISK.DVD Ram disk | FILES = 20 |
- DEVICE = MOUSE.SYS Mouse driver | BUFFERS = 20 |
- DEVICE = SPOOL.DEV Print Spooler | DEVICE = ANSI.SYS |
- -------------------------
- When you change CONFIG.SYS, you must REBOOT (CTRL-ALT-DEL) to effect
- the changes. P.S. Device Drivers are files which must be on disk.
