Working with Windows NT 4.0
This section describes how to customize the OmniBook for use with Windows NT
4.0 including the following:
Using Windows NT 4.0 Advanced Power Management features.
Adjusting PC speaker defaults.

To use Windows NT 4.0

Windows NT 4.0 is not Advanced Power Management (APM) aware or Plug and
Play (PnP) compatible. If you are not using the Windows NT 4.0 OmniBook Mobile
Enhancements, the following will occur:
PC cards (PCMCIA) cannot be hot swapped into any laptop with Windows NT.
Windows NT 4.0 does not support dynamic allocation of resources. PC cards
must be inserted into the unit before booting.
PC card sockets are not enabled after resuming. PC cards are inoperable after a
true suspend then resume cycle. Rebooting restarts the sockets.
The operating system's clock is stopped when suspended and does not re-
synchronize with the hardware clock when resuming. When users resume NT's
clock starts up exactly where it was when they suspended. Rebooting resets the
clock.
The OmniBook's Display Off (pressing the blue On/Off button with ac inserted)
mode does not cause these symptoms since only the display, keyboard, sound,
and mouse are turned off by the BIOS. The CPU and network cards are still
active and operating normally.
