The Montara-GM GMCH Host Memory Controller integrates a high performance host interface for Intel Banias
processor, a high performance 2D/3D Graphic Engine, a high performance memory controller, Digital Video port
(DVOB & DVOC) interface, and Intel Hub interface Technology connecting with Intel 82801DBM ICH4-M.
The Intel ICH4-M integrates three Universal Serial Bus 2.0 Host Controllers Interface (UHCI), the Audio Controller
with AC97 interface, the Ethernet includes a 32-bit PCI controller, the IDE Master/Slave controllers, and Intel Hub
interface technology.
The VIA VT6105LOM “Rhine III” Ethernet controller is a cutting edge, feature-rich, and cost-competitive single
ASIC chip solution for PC “LAN On Motherboard” applications or Low Cost NIC applications. The 6105LOM eases
server processor utilization by optimizing throughput between NIC and PCI bus allowing data transfers of up to at
200Mbps in full duplex mode, without using the system CPU. The VT6105LOM contains advanced power
management feature for low power consumption including Wake On LAN (WOL) and is implemented using a low
power 0.22-micron design.
The R5C551 is the single chip solution offering single PCI bus-PC Card Bridge. The R5C551 is compliant with the
latest specification in both PC card and IEEE 1394. The R5C551 has two PCI functions compliant, the PC Card
interface and the IEEE 1394 interface. The PC Card controller of the R5C551 is compliant with PC Card Standard
Release 7.0. The R5C551 provides features that make it the best choice for bridging between the PCI bus and PC
Cards, and supports any combination of 16-bit (Card-16), and CardBus (Card-32) PC Cards in one socket, powered at
5V or 3.3V, as required. The R5C551 provides the IEEE1394 OHCI-Link and two ports the IEEE1394 PHY that are
compliant with the IEEE1394-1995, IEEE1394a-2000 and the latest 1394 OHCI specifications. The R5C551 data rate
is capable of 100, 200, and 400Mbits per second.The R5C551 is compliant with the latest PCI Bus Power
Management Specification, and provides several low-power modes that enable the host power system to further reduce
power consumption.
