Windows shuts down automatically when the shell program exits.  However,

because NORSHELL does not exit, it shuts Windows down when it detects that

the application from the 

NorShellRun

 line no longer exists.  An application may

shut down Windows on its own by calling the Windows 3.1 ExitWindows

function.  This is the preferred method.

The NORAPM.DLL driver provides a Windows interface to the APM BIOS

extensions.  The driver's functions include the following:

"

Idling the CPU when Windows has nothing to do.

"

TimingĆout the backlight and suspending the computer after periods of user

inactivity.

"

Warning the user about critical power management events, such as low

batteries, unless an application wants to take over that responsibility.

"

Broadcasting APM event codes to Windows applications and drivers and

DOS TSRs.

"

Providing a Windows API for APM functions, such as setting and getting

the power state of system components.

The NORAPM.DLL version number is logged into the NORAPM.DLL= entry in

the [boot.description] area of the SYSTEM.INI file each time Windows is started.

NORAPM.DLL is a Windows 3.1 installable driver.  The APM 1.1 BIOS

extensions are required to be installed before Windows is started.  The APM

BIOS (that NORAPM needs) may come from the builtĆin system BIOS or from a

separate DOS TSR, NORAPM.EXE, which must be run before Windows is

started.  To install NORAPM.DLL:

Place a keyword (e.g., power) on the drivers=" line, and add a line to the

[drivers]" section of SYSTEM.INI, equating that keyword with the actual

path to the power management driver.  However, if this path is included in

the DOS path, then use the name of the power management driver,

NORAPM.DLL.  Also, the power management keyword should be first on

the 

drivers=

" line.

The following is an example of a section of the SYSTEM.INI file, showing a

typical installation.

[boot]
drivers= power pen penwindows scanner npcp irda

[drivers]
power=norapm.dll
pen=norpen.dll

drivers= Tells Windows to load the installable drivers.  This list of drivers is the

standard set (and organized in the exact order shown in the example above).

The significant drivers here, are power and pen.  These are token names for the

drivers.  The actual driver names are defined in the 

[drivers]

 section of the

SYSTEM.INI file (e.g., 

power=

, 

pen=

, etc.).

power= Tells Windows the actual name of the installable Power Management

driver named in the 

[boot]

 section of the SYSTEM.INI file (listed above).
