The M722 model motherboard would support the Mobile Pentium III processor at 500/600*/650* /700*/750*/800*MHz uPGA2 package on
board and Celeron 450/500/550/600/650/700MHz uPGA2 package .(*Enabled with IST,Intel Speedstep technology)
This system is based on PCI architecture and is fully compatible with IBM PC/AT specification, which have standard hardware peripheral
interface and support Intel Mobile Pentium III/Celeron (uPGA2) family. The power management complies with Advanced Configuration and
Power Interface (ACPI) 1.0. It also provides easy configuration through CMOS setup, which is built in system BIOS software and can be pop-up
by pressing F2 at system start up or warm reset. System also provides icon LEDs to display system status, such as Power indicator, LAN,
HDD/CDROM, NUM LOCK, CAP LOCK, SCROLL LOCK, SUSPEND MODE and Battery charging status. It also equipped with Zoom Video
capture port, FIR, 4 USB ports, and 3D stereo audio functions.
The memory subsystem supports 64MB SDRAM on board and one 144pin DIMM socket for upgrading up to 192MB or 256 MB of DRAM
using PC-100 SDRAM DIMM module.
The 82440MX Chipset integrated the North Bridge chipset (without AGP) and the South Bridge chipset while adding a two channel, digital
AC’97.2 links feature. 82440MX Chipset brings second important firsts to the mobile PC environment: (1) Concurrent PCI (PCI 2.1) reduces
CPU latencies for smoother video and more realistic audio; (2) Universal Serial Bus (USB) technology makes Plug and Play peripheral
connections a reality. The Intel 82440MX Chipset also contains an integrated PCI Bus Mastering IDE controller with one high performance IDE
interfaces and supports

synchronous DMA mode which transfers up to 33 Mbytes per second. In addition, the 440MX Chipset
supports Intel's new Dynamic Power Management Architecture (DPMA) for consuming less power consumption than earlier PCIset designs and
supports Advanced Configuration and Power Interface (ACPI) 1.0 for longer battery life in mobile systems.
The ATI 3D RAGE Mobility-M VGA controller integrated with 4Mbyte SDRAM provides LCD, and CRT simultaneously and supports 2D and
3D acceleration, ZV port, DVD, ACPI power management, integrated LVDS…etc. The TI 1410 CARDBUS controller supports PCMCIA and
CARDBUS. The National Semiconductor PC97338 Super I/O controller integrates an IrDA 1.1, 1.0 and sharp ASK compatible infrared interface
To provide for the increasing number of multimedia applications, the AC97 CODEC CS4299 is integrated onto the motherboard which contain
3D digital audio output.
A full set of software drivers and utilities are available to allow advanced operating systems such as Windows 98 to take full advantage of the
hardware capabilities such as bus mastering IDE, Windows 95-ready Plug & Play, Advanced Power Management (APM) and Advance
configuration and power interface (ACPI).
Following chapters will have more detail description for each individual sub-systems and functions.
