1-2 System Overview
This section provides an overview of the NEC PowerMate ES 5250
®
Series
computer, an enhanced version of the PowerMate ES 5200 Series computer.
Included in this section are descriptions of components that differ from those in
the NEC PowerMate ES 5200 Series. Also included is an overview of several
build-to-order options available for the PowerMate ES 5250 Series of
computers.
Hardware and technical information that is common between the PowerMate ES
5250 series and the PowerMate ES 5200 series is not included in this addendum.
The reader should refer to the NEC PowerMate ES 5200 Series Service and
Reference Manual for common component information.
Externally, the front and back of the PowerMate ES 5250 series do not differ
from the PowerMate ES 5200 series. Internally, the PowerMate ES 5250 uses an
enhanced Micro-Star MS-6131 (rev 3.0C) system board with onboard

82559 10/100 Ethernet network chip
!
support for a Pentium

III 600-MHz processor with 100-MHz front side
bus (FSB).
Additionally, support is included for an Adaptec
®
2940 Ultra2 Wide SCSI
adapter board and high capacity Enhanced IDE (EIDE) and small computer
system interface (SCSI) 7200 rpm hard drives.
See the following sections for additional information on the system board, SCSI
adapter board, and hard drives.
System Board
The Micro-Star MS-6131 Rev. 3.0C NLX system board supports Intel Celeron
®
processors (up to 433 MHz), Pentium II processors (up to 450 MHz), and
Pentium III processors (up to 600 MHz). The board uses the same Intel
82440BX PCI chipset, system memory, audio controller, clock, I/O controller,
battery, and hardware monitor as the system boards used in the PowerMate ES
5200 Series.
Enhancements to the board include the addition of the ATI
®
3D RAGE XL
™
graphics accelerator chip, 8 MB of video memory, Intel 82559 10/100 Ethernet
network chip, and support for the Pentium III 600-MHz processor and 7200 rpm
EIDE and SCSI hard drives.
ATI 3D RAGE XL Graphics Accelerator
The ATI 3D Rage XL graphics accelerator chip on the system board provides
high quality full accelerated graphics port (AGP) 2X acceleration and 2D, 3D,
and video acceleration.
