1. Hardware Engineering Specification
1.1 Introduction
The MiTAC 8066MP model is designed for Intel Mobile Pentium-M Processor and Celeron-M Processor,Dothan
400 and 533 FSB.
t ent
This system is based on PCI architecture and is fully compatible with IBM PC/AT specification, which has standard
re m
hardware peripheral interface. The power management complies with Advanced Configuration and Power Interface.
ec u
It also provides easy configuration through CMOS setup, which is built in system BIOS software and can be pop-up
S c
by pressing F2 key at system start up or warm reset. System also provides icon LEDs to display system status, such
ac l Do
as Wireless LAN indicator, AC/Battery Power indicator, Battery status indicator, CD-ROM, HDD, NUM LOCK,
iT ia
CAP LOCK, SCROLL LOCK. It also equipped with GIGA LAN, 56K Fax MODEM, 3 USB port, S-Video, line in,
M t
SPIDIF, and internal/external microphone function.
en
The memory subsystem supports DDR2 SDRAM channels (64-bits wide).

The 915GM MCH Host Memory Controller integrates a high performance host interface for Intel Dothan processor,
C
a high performance PCI Express interface, a high performance memory controller, Digital Video port (DVOB &
DVOC) interface, and Direct Media Interface (DMI) connecting with Intel ICH6-M.
The Intel ICH6-M integrates three Universal Serial Bus 2.0 Host Controllers Interface (UHCI), the Audio
Controller with Azalia interface, the Ethernet includes a 32-bit PCI controller, the IDE Master/Slave controllers, the
SATA controller and Direct Media Interface technology.
