- This page gives you information about various programs that are typcially
- loaded into memory.
-
- Some memory resident programs use a special interrupt to communicate with
- other programs. By giving a special 'signature' with the command, many
- programs can share this one interrupt.
-
- DOS: Checks if DOS is readable!
-
- DRIVER.SYS: This is used to add in extra floppies, or to redefine a drive
- that is not normally supported. Also, DOS 4 and newer
- appear to support some of it's functions.
-
- DISPLAY.SYS: This is used when non-US display characters are needed.
-
- ANSI.SYS: This lets you display color, control the cursor, and
- re-define keys.
-
- This check is supported by DOS 4 and newer ANSI.SYS, and the
- 5/91 (or newer) version of NNANSI. Other versions will
- probably not be detected.
-
- EGA.SYS: This is used by Windows 3. Some of the registers used to
- control the EGA are WRITE ONLY. EGA.SYS is an interface that
- lets Windows keep track of things easier. Some mouse drivers
- also support these calls.
-
- PRINT: This is DOS's program that will send a file to the printer
- while running in the background. If PRINT is found, INFOPLUS
- will display information about it on the right side of the
- screen.
-
- ASSIGN: ASSIGN lets you redefine drive letters. ASSIGN A=B B=A will
- reverse the drive letters used by your floppies. ASSIGN by
- itself cancels all redefinitions.
-
- SHARE: This is used to control access to files in network and
- multi-tasking environments. Under DOS 4, it also prevents
- problems when FCBs are used on large partitions.
-
- NLSFUNC: This is used when non-US displays and keyboards are wanted.
-
- GRAFTABL: The CGA lets you redefine the upper 128 ASCII characters in
- graphics mode. GRAFTABL loads the normal high-ASCII
- characters for display. There are two entries, one for DOS 4
- and older, the other for DOS 5 and newer.
-
- NETBIOS: This is an interface for networking.
-
- SHELLB: This is part of DOS 4's DOSSHELL program.
-
- XMA2EMS: This is a program for PS/2's that convert extended memory to
- EMS memory.
-
- APPEND: Append lets you specify a PATH that is used when a program
- attempts to open a file. It works similar to the PATH command
- used at the DOS prompt. If found, extra information will be
- displayed on the right side of the screen.
-
- GRAPHICS.COM: This is a DOS program that lets the PrtScrn key print
- graphics screen.
-
- Crit.err.handlr: When a critical error occurs, it's possible to have a
- special TSR handle things.
-
- CDROM: Some CDROM's might use this interface.
-
- Network: This is supposed to be a generic Network information call.
-
- DOSKEY: This is the command line editor for DOS 5.
-
- DOS Extender: This is a new standardized check for DOS extenders. DOS
- extenders allow programs to run in protected mode, accessing
- more than 1M of memory.
-
- SETVER list: SETVER is a DOS 5 command that allows you to change the
- version of DOS that a program sees. There are many programs
- already set in the default configuration. You must re-boot
- DOS to put any changes into effect.
