- BREAK=<ON or OFF>
- Default: OFF
- Purpose: Used to estaoblish MS-DOS's response to the Ctrl
- Break key combination. If OFF MS-DOS responds to
- Ctrl-Break only during screen, keyboard, serial
- port, or printer I/O operations. If ON MS-DOS
- responds to Ctrl-Break for all operations.

- BUFFERS=<size>
- Default: 2 on PC's or 3 on AT's
- Purpose: Used to determine number of disk buffers that are
- reserved for use by MS-DOS. Generally, setting the
- buffers value to 16 is adequate, although some
- applications require as much as 64. Setting this
- value too high (20+) or too low can slow your
- system down. You need to experiment to determine
- the best setting for your machine and application
- setup.

- FILES=<size>
- Default: 8
- Purpose: Used to adjust the total number of files that can
- be open at one time. Note for each additional file
- specified, 48 to 58 bytes of additional RAM is
- used. Setting of 20 to 25 is adequate under most
- conditions. 50 or more is adequate for Windows
- and up to 100 if using Windows on a Network. Also
- note some users noted fewer Application errors in
- Windows when FILES=size was increased.

- DEVICE=<Drive:\Path\Filename parameterlist>
- Default: none
- Purpose: Crucial to configuring your system for different
- types of hardware. This is how special files called
- Device Drivers (files which normally have the
- extension .SYS) are loaded into memory.
- Drive = Drive file is on, Path = the directory this
- file resides in, Filename = the name of the file,
- and parameterlist = any parameters for Filename
- Device Driver.
- ····························································
- SHELL=<Drive:\Path\Filename parameterlist>
- Default: COMMAND.COM
- Purpose: Used to determine which Command Processor or Shell
- to loaded at Boot.Drive = Drive file is on, Path =
- the directory this file resides in, Filename = the
- name of the file, and parameterlist = any parameters
- for Filename command processor.

- LASTDRIVE=<Drive:>
- Default: E:
- Purpose: Used to determine the number of drives on the
- system to be recognized by MS-DOS. MS-DOS is able
- to recognize 26 drives starting at A: and ending
- with Z: Note that each drive added requires an
- additional 81 bytes of memory for DOS versions
- less than 4.0 and 88 bytes for versions 4.0 and
- higher.
