1.   General Description and Installation

PowerProfiler for Windows NT provides a complete power management
solution for portable platforms running Microsoft's Windows NT
4.0 environment. PowerProfiler provides suspend/resume control,
active battery status and metering, and a wide variety of user
selectable parameters and alarms all within an easy to use Windows
application. It includes an APM 1.2 kernel driver that interfaces
with an APM BIOS. PowerProfiler for Windows NT is a generic product,
and is platform independent.

PowerProfiler resides on two diskettes. To install, run Setup.exe 
on Disk 1.

If you have the single file pp220gne.exe, this is a self-extracting
.ZIP file. Copy to a directory, double click to unzip, and run 
Setup.exe. To create diskette images, from the DOS prompt run 
'pp200gne -d [<path>]'

3.   Things to Know

  - Occasionally, an error message may appear upon resume:
  "System Process - Lost Delayed - Write Data.   The system was
  attempting to transfer file data from buffers to
  \Device\Hardisk0\Partition1\$Mft. The write operation failed,
  and some of the data may have  been written to the file."
  PowerProfiler forces a flush of all disk buffers prior to
  suspend. No evidence of any lost data has been found. This problem 
  has only been observed on some platforms - most do not exhibit the 
  problem. It has been reported that on at least one platform that has
  this problem, the atapi.sys driver can be changed to the original NT
  4.0 version (rather than the service pack version) and the problem 
  goes away.

  - On rare occasions we have observed following a Resume operation 
  that no applications can be launched, though the mouse can be moved 
  and the system does not appear to be hung. This problem has only 
  been observed on some platforms - most do not exhibit the problem. 
  It is recommended that prior to suspending the user should save data.
  This appears to be related to the above problem since it also only 
  occurs on the same systems that exhibit the previous problem.  Same 
  recommended fix applies as for above.

  - Problems occur if PowerProfiler is installed by Administrator and 
  uninstalled by a user. Uninstall appears to complete with no 
  problems, but on reboot error messages may appear, and some 
  PowerProfiler components are not removed. It is recommended that 
  only the administrator installs/uninstalls PowerProfiler to avoid 
  any problems.  

4. Problems Addressed in this Release

  Service pack 4 beta release crashes (blue screen) during boot when 
  PowerProfiler is installed.  This occurs because of changes to NT
  in SP4 related to the interrupt descriptor table.  PowerProfiler has
  been modified to fix this problem.
