der for the changes to be recognized.

Installing the Mouse Driver

The Disk 3 of the NEC Versa 550 Series notebook diskettes contains the Logitech mouse
driver and System Utility program. The Logitech mouse driver program allows you to en-
hance the operation of the built-in trackball. Run the "INSTALL.EXE" program under the
MOUSE subdirectory to automatically install the mouse driver for DOS and Windows envi-
ronment. Consult the README files inside the diskette for more important information.

Applying the System Utility Programs

The Disk 3 of the NEC Versa 550 Series notebook diskettes also contains two important
system utility program under the PHDISK subdirectory: TIME.SYS and PHDISK.EXE.

TIME.SYS Driver

The TIME.SYS device driver included with the NEC Versa 550 Series ensures that the
system time is properly updated while the system is in suspend mode. The TIME.SYS
driver can be loaded into memory by adding the a device command line to the
CONFIG.SYS file on the hard drive:
where PATH represents the drive and directory where the TIME.SYS is located.
When using Windows 95, there is no need to load TIME.SYS.
device=<PATH>\time.sys
NOTE: Although an APM driver such as the
DOS POWER.EXE utility will also update the
system time if loaded, it is highly recommended
that the TIME.SYS driver be loaded into mem-
ory as well. If both the APM driver and the
TIME.SYS driver are to be loaded into the
memory, the TIME.SYS should be loaded first
before the APM driver.
