How to use this guide
Thismanualiswrittento help youuse the MAXI6560. The manual describes
how to arrange various settings on Intel MMC1 and MMC2 CPU module to
meet your requirements. It‘s briefed as follows:
Chapter 1, “Introduction” gives an overview of the product‘s
specifications. Italso tells you what are included in the product package.
Chapter 2, “Switches and Connectors” describes the definitions and
positions of Switches and Connectors that you may easily configure and set
up per your requirement.
Chapter 3, “Capability Expanding” describes how to change or expand the
CPU Board by changing system memory, cache memory, and CPU to get
more power out from the CPU board.
Chapter 4, “Award BIOS Setup” describes how to use the advanced
PCI/GreenBIOS to controlalmost every featureof the MAXI 6560, including
watchdog timer.
The Appendix 1 describes how to set up Watch Dog Timer (WDT) and gives
an example to program the WDT.
The Appendix 2 describes the memory mapping of MAXI 6560 for user’s
reference in add-on card or programming.

Introduction
Welcome to MAXI 6560 –the new generation Compact PCI CPU board. The
MAXI 6560 is a brand new generation of advanced technologies. It’s based
upon Intel’s notebook architecture and achieves the widest ever CPU support.
With unique MMC1 and MMC2 architecture,the MAXI 6560 could support Intel
Mobile Module (IMM),with Pentium from 166 MHz to 266 MHz,and Pentium II
from 233 MHz to 300 MHz. It also supports the new generation of Pentium II
module, up to 100 MHz external bus andover 500MHz CPU clock in the near
future through the sophisticated MMC2. It’s excellent to the system integrators
ruggedized equipments vendors who needs the widest selections of computing
power on the same basic design.
The MAXI 6560 is the only one product in the world,which could support three
CPU families on the same design. The user now could put on the Pentium IMM,
e.g. 200 MHz –for acceptable performance and low power consumed as well as
low heat generated. Or he can upgrade to Pentium II 300 MHz if the Top
performance is the priority. The memory support is 64 MB or 128 MB SDRAM
mounted on board for real ruggedized applications. One additional SO-DIMM is
reserved to double the memory size if necessary. The computing power is kept
high and growing even higher when CPU and memory getting faster and larger.
The MAXI 6560 adopts the brand new C&T 69000 VGA/panel controller from
Chip & Technologies with the embedded 2 MB SDRAM. This chip can support
TFT panel up to 1280 x 1024,256 color,75 Hz or support CRT up to 1600 x 1200,
256 color,60Hz. This is good enough for any embedded display. The Intel
82558 Single Chip Ethernet controller is on board. The MAXI 6560 now could
support either 10 base T or 100 Base TX complied with the industry standard.
(Intel’s LAN solution is one of the major standards in the industry!) The
Advanced Adaptec AIC 7890, the ultra 2 SCSI controller is also on board to
provide the no compromise I/O solutions with the 80MB per second data rate, the
MAXI 6560 could be used the powerful server in the harsh environments.
All the standard IPC features,such as four serial ports,one parallel port,high
precision RTC,keyboard mouse ports,and the USB are all standards on board.
The SIO COM1/COM3are also optional for RS422/485. The socket for Disk On
Chip, which is the important feature for the Embedded Application is also
reserved. The single chip DOC memory size could be as large as 72 MB; big
enough for various applications.

MAXI 6560 User's Guide
Specifications 1-2
One special feature of the MAXI 6560 isthe Front I/O, Rear I/O options. Now
the connectors and cables all go from the rear side. This makes a clean operation
environment and significantly shortens the MTTR. The MAXI 6560 also
supports the PICMG Hot Swap spec. (PICMG 2.1). So the product is really
suitable for the mission critical applications. All these I/O’s are arranged
through J4 & J5. As to J1 & J2, they are reserved for the primary cPCI channel,
supporting up to 7 cPCI slots.
The notebook type floppy connector and IDE connector are reserved. The watch
dog timer is on board. The Flash ROM BIOS is also standard for easier BIOS
update. The IDE supports mode 4 PIO,mode 2 DMA master and ultra DMA/33.
The MAXI 6560 will be available with four models, depending on the memory size
mounted on board and Front/Rear I/O’s as the following table shows:
Feature
Model Common Features Memory Size I/O
MAXI 6560F/64 YES 64MB Front
MAXI 6560F/128 YES 128MB Front
MAXI 6560R/64 YES 64MB Rear
