Notice
Dear Customer,
Thank you for purchasing the PCM-5894/5892 board. This
user's manual is designed to help you get the most out of the PCM-
5894/5892, please read it thoroughly before you install and use the
board. The product that you have purchased comes with a one-
year limited warranty, but AAEON will not be responsible for
misuse of the product. Therefore, we strongly urge that you first
read the manual before using the product.
To receive the lastest version of the user manual, please visit our
Web site at:
http://www.aaeon.com

The PCM-5894/5892 adopts a "P9" type power connector
for operation.
Please be advised that the PCM-5894/5892 Rev.A3 or higher
revision requires a "P9" power connector for proper operation.
On the standard PS/2 power supplies, there are usually two
similar 6-pin power plugs. P8 has one +5V output while P9 has
three. +5V is normally indicated by red color so you should be
able to distinguish P9 from P8 by counting the number of red
wire. Many times, there are also markings on these two plugs
indicating which is which.
NOTE : Without any aditional devices, PCM-5894/5892
alone is +5V operational. -5V of P9 power
connector is not required.
** PLEASE be absolutely certain that you are using the correct
plug before continuing.
AAEON will not be responsible for any damages caused
by improper power input.

2PCM-5894/5892 User Manual
Introduction
The PCM-5894/5892 is a Pentium single board computer with
one onboard PCI SVGA controller, one PCI Ethernet interface
and one PCI expansion slot. Equipped with a 64-bits local bus
architecture, the PCM-5894/5892 releases Pentium's full
potential and provides unprecedented performance compared to
current 32-bit processor boards. The PCM-5894/5892 offers all
the functions of an industrial computer on a single board, but fits
in the space of a 5¼" floppy drive (only 5.75" x 8"). For maximum
performance, the PCM-5894/5892 also supports a 512 KB. L2
cache onboard. An SSD interface supports one 32-pin DIP socket
for the M-Systems DiskOnChip 2000 series, memory capacity
from 2MB to 72MB.
Onboard features include four serial ports (three RS-232 and one
RS-232/422/485),onemulti-modeparallel(ECP/EPP/SPP)port,one
floppy drive controller and one keyboard/PS-2 mouse interface.
The built-in high speed PCI IDE controller supports both PIO and
bus master modes. Up to two IDE devices can be connected,
including large hard disks, CD-ROM drives, tape backup drives,
and other IDE devices.
ThePCM-5894/5892 also features power management to minimize
power consumption. It complies with the “Green Function”
standard and supports three types of power saving features: Doze
mode, Standby mode, and Suspend mode. In addition, the board’s
watchdog timer can automatically reset the system or generate an
interrupt in case the system stops due to a program bug or EMI.
Onboard peripherals with true PCI
performance
The PCM-5894/5892 is a highly integrated, all-in-one single board
computer. All onboard peripherals (including PCI flat panel/VGA
interface, PCI Ethernet, and PCI IDE) adopt PCI technology and
operate through an internal PCI bus. Integrating a Pentium board
with a PCI architecture has unleashed a revolutionary level of
performance. The PCM-5894/5892 is one of the smallest and
most powerful all-in-one Pentium boards available.
