This function saves power when the system is idle and performs a CPU Idle call

prior to passing on the interrupt.

NPOWER is basically implementing a subset of the following function calls.  The

function 547Fh is a new function that is unique to NPOWER.  The following is a

list of the functions implemented by NPOWER.  See the Interrupt Definitions

paragraph in Section 6 for further details.

This interrupt is intercepted to turn the backlight back on when the global

backlight timer is enabled.  A touchscreen driver must be installed and that

driver must pass the interrupt on to NPOWER rather than handling the EOI.

The definitions of the 4000 Series interrupts supported by NORAPM.EXE, the

APM BIOS, are identified by the symbolic notation, NORAPM.

"

NORAPM.EXEĆsupported APM interrupts are listed in Table 2Ć1.  Note that

NORAPM can be configured with certain switches to ignore specific interrupts.
