PHDISK.EXE Utility
The PHDISK.EXE utility included with the NEC Versa 550 series is used to create a spe-
cial hard disk partition where the contents of the system memory are saved whenever the
Suspend save-to-disk (STD) feature is invoked. The
PHDISK.EXE
utility automatically
calculate the size of installed system memory, excluding video memory, and create an ap-
propriately sized partition on the hard drive. Note that save-to-disk partition must be cre-
ated or reserved when you first configure the hard disk, and that
PHDISK.EXE
can only be
run under DOS environment.
PHDISK.EXE
has the following syntax:
PHDISK [options]
where [options] include the following parameters -
/Create [KB] to create and format a STD partition in KB size
/Reformat to reformat an existing STD partition
/Delete to delete the existing STD partition
/Info to show detailed information about the STD partition
/Vram size
to override the default video ram size of 1024KB
Always reboot the system after you have created or deleted the STD partition so that the
NEC Versa 550’s PMU (Power Management Unit) can establish the correct suspend mode.
SYSTEM UPGRADES
The NEC Versa notebook is easily upgradable to a faster more powerful microprocessor
and higher capacity hard drive. In addition, you can add an optional second memory module
to increase the system memory to as much as 24MB. This section provides the settings
needed as well as illustration in upgrading the system.
Memory Upgrade Procedure
The NEC Versa notebook allows you to install and expand the on-board 8MB (4MB for
NEC Versa 500D1) system memory via the memory compartment found at the base of the
notebook. Inside the compartment is an extra memory module socket which can accommo-
date any standard JEDEC 4MB, 8MB, and 16MB SIMM modules.
