NORAND Proprietary System functions are part of the INT 15h interface for the

PEN*KEY 6000 Series platforms.  These interrupt functions are provided by

NORAPM.EXE and are callable only after NORAPM.EXE is loaded.
The interrupts can convert applications from the 4000 Series platform to the

PEN*KEY 6000 Series platforms.  See the Interrupts paragraph in Section 6.
When creating new applications, see the APM BIOS Interface Specification 1.1

publication from Intel Corporation for portable definitions of the functions

required for these system interfaces, rather than using the following interrupts.

Call these functions by loading register AX with 5380h, loading the other

registers in the function description, and issuing a call to INT 15h.  Each

function returns with the carry flag cleared and AH equal to zero if the function

succeeds.  If the function fails, each function returns with the carry flag set and

AH set to an error code.

A list of the NORAND Proprietary System interrupts, supported by the Power

Management BIOS, are included with the other Power Management interrupts,

as shown in Table 2Ć1 on page 2Ć12.  The Power Management interrupts are

identified by the symbolic notation, NORAPM.

CLOCK.EXE is part of the APM system when running under DOS.  CLOCK is a

device driver that replaces the standard DOS clock driver.  It must be installed

as a device driver at system startup time.
Besides the normal clock driver functions, CLOCK makes sure that the date and

time are maintained during suspends.  It does this by forcing a read from the

CMOS realĆtime clock upon Resume.

CLOCK is installed as a device driver in the CONFIG.SYS file.  CLOCK should

be installed after NPOWER.EXE.  A typical entry in CONFIG.SYS to install

CLOCK would look like this:

DEVICE=NORAPM.EXE
DEVICE=NPOWER.EXE
DEVICE=CLOCK.EXE

After installation, CLOCK displays the following message:

CLOCK.SYS:  NORAND DOS Clock Driver
Version n.nn
Copyright (c) nnnn by Norand Corporation

There are no installation switches or userĆprogrammable parts of CLOCK.EXE.
