Introduction MPE-PNTM System Board
Introduction
Handling Precautions
The MPE--PNTM contains electronic components
that are highly sensitive to electrostatic discharge.
Use extra caution when handling the MPE--PNTM to
ensure there is adequate grounding around the work
area the board is being installed. ALWAYS wear a
ground strap or ground your body by touching a
grounded object such as an unpainted--painted metal
device connected to power ground.
The MPE--PNTM has delicate crystal oscillators that
can break if subjected to sudden shock such as being
tossed on a table. Use care when moving the MPE--
PNTM from point to point.
If Troubles Are Encountered
If, during the course of installation or operation of the
MPE--PNTM, the board displays improper operation,
first consult this manual's Troubleshooting section,
paying particular attention to the jumper settings, as
well as the BIOS CMOS options. Then contact your
dealer or distributor for additional information. Deal-
ers and Distributors may contact Mylex Technical
Support Department at (510) 796--6100. Be sure to
have the enclosed System Problem Report com-
pletely filled out.

MPE-PNTM System Board Introduction
Overview
General Description: The MPE--PNTM is a
full sized AT form factor PCI--EISA system
board based on the Intel Pentium microproc-
essor. ThehighlyintegratedASICdesign pro-
vides high performance coupled with a list of
features including: three PCI master slots,
seven bus master EISA slots, Pentium proc-
essor, optional 256K/512K of secondary
write--back cache, up to 192MB of DRAM, in-
tegrated I/O for serial, parallel, IDE and high--
speed floppy drive control and FLASH PROM
BIOS.
EISA BUS Architecture:
EISA has emerged
as the defacto standard for a 32--bit PC BUS.
Backward compatible with the original AT
BUS, as well as providing the highest per-
formance available from a PC standard bus --
33 MB/sec -- , EISA is the architecture of
choice. All slots on the MPE--PNTM are “Bus
Master” and “Burst Mode” compatible ensur-
ing EISA adapter compatibility.
PCI Bus Architecture:
PCI is an emerging
de--facto standard local bus for high--end PC
systems. PCI supports data burst transfer
rates of 132MB/sec. at 33MHz. High speed
peripherals and graphics cards can use the
PCI bus to transfer data at high speed. The
MPE--PNTM supports 3 PCI expansion slots.
Theboardalso hasabuilt--inSCSI--IIcontrol-
ler residing on the PCI bus.
192MB of DRAM Memory:
While most sys-
tem boards only support 32 or 64MB, the
MPE--PNTM quadruples that memory capac-
ityup to 192MB. Thisisamustfor network file
servers and multi--user, time--sharing sys-
tems. The MPE--PNTM supports the new 72
pin standard single as well as double sided
modules of 256Kx36, 512Kx36, 1Mx36,
2Mx36, 4Mx36, 8Mx36.

Introduction MPE-PNTM System Board
Introduction
256K--512K of Write--Back Cache Memory (Sec-
ondary Cache):
Cache memory is an essential part
of maintaining high system performance. In most
cases, the larger the cache memory, the greater the
system performance. Repetitive programs such as
spread--sheet and CAD applications will benefit the
most. The standard configuration does not include
Cachememory.Toalloweasyupgradeof cache mem-
ory, the SRAM module is used, allowing256K/512K of
cache using standard or burst SRAMs.
Unlike other cache architectures that require the CPU
to write directly to DRAM, the write--back cache is the
most efficient way for cache to write information back
to main memory. This is because the cache can be
written to faster than DRAM. Then the cache circuit
writes the information to the DRAM by itself. The sec-
ondary cache can be set up to operate in write--back
or write--through mode.
Embedded I/O:
The MPE--PNTM includes the latest
generation of Super I/O controllers which provides 2
serial ports, a parallel port, IDE disk interface and
floppy disk controller. The floppy disk controller is ca-
pable of supporting the new “4MB” floppy disk drives.
Just as important, the floppy controller is capable of
data rates of 1MB/sec--—this is a significant benefit in
performance on various floppy tape drives compatible
with the 1MB/sec transfer rates. In addition, the serial
portUARTSare compatiblewith theNational™ 16550
with 16--byte FIFO.
FLASH ROM BIOS:
At one time or another, the need
can arise to update the system BIOS. Usually this
means that the system must be partially disassem-
bled, the old ROM chip removed, discarded, the new
ROM chip installed and the system reassembled.
WithFLASH technology, BIOSupdates aremadesim-
ply by running a program. With the MPE--PNTM there
are no chassis to open, no jumpers to set. Simply run
a DOS program that reads a BIOS binary image file
and then programs the new BIOS into the FLASH
memory chip.
