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 appears 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 and control the cursor.
              Currently, only DOS 4's ANSI.SYS is detectable this way.
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.
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.
NETBIOS:      This is an older 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.
