Chipset
Intel’s Lakeport (945G/P) chipset consists of two primary components: the Graphics
Memory Controller Hub (GMCH)/Memory Controller Hub (MCH) and the I/O
Controller Hub (ICH7). Optimized for the Celeron, Pentium 4, Pentium D processors
in an LGA775 Package, the Lakeport (945G/P) provides the performance and
feature-set required for high-end UP dual core processor desktop solutions.
The GMCH/MCH supports high-performance integrated graphics and manage the
data fl ow of the following fi ve interfaces: the CPU interface, DDR2 interface, PCI
Express Graphic Interface, the DMI (Direct Media Interface) and integrated graphics
with display interfaces (*GMCH only) . The GMCH/MCH supports a FSB frequency
of 533/800/1066 MHz using a scalable CPU. It supports up to two channels of
non-ECC DDR2 400/533/667 SDRAM. The integrated Graphics Controller provides
3D, 2D and display capabilities. The GMCH/MCH also supports advanced desktop
power management.
Universal Serial Bus (USB)
The Motherboard can support up to eight USB ports; two USB ports can be located
on the I/O shield. For more than two USB devices, two USB headers can be
connected to the board. The Motherboard fully supports the universal host controller
interface (UHCI) and uses UHCI-compatible software drivers. USB features include:
? Self-identifying peripherals that can be plugged in while the computer is running.
? Automatic mapping of function to driver and configuration.
? Supports isochronous/asynchronous transfer types over the same set of wires.
? Supports up to 127 physical devices.
? Guaranteed bandwidth and low latencies appropriate for telephony, audio, and
other applications.
? Error-handling and fault-recovery mechanisms built into the protocol.
Note: Computer systems that have an unshielded cable attached to a USB port
may not meet FCC Class B requirements, even if no device or a low-speed
(sub-channel) USB device is attached to the cable. Use shielded cable that
meets the requirements for high-speed (fully rated) devices.
IDE Support
The VIG385P Motherboard has one independent bus-mastering PCI IDE interface.
These interface supports PIO Mode 3, PIO Mode 4, ATAPI devices (e.g., CD-ROM),
Ultra DMA/33, Ultra DMA/66 & Ultra DMA/100 synchronous-DMA mode transfers.
The BIOS supports logical block addressing (LBA) and extended cylinder head
sector (ECHS) translation modes. The BIOS automatically detects the IDE device
transfer rate and translation mode.
