Desktop Board Features

USB 2.0 Support

The Desktop Board supports up to seven USB 2.0 ports (three ports routed to the back panel and four ports routed to two front panel USB 2.0 headers). One of the front panel USB headers supports an Intel Z-U130 USB Solid-State Drive (or compatible device). The USB 2.0 ports are backward compatible with USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1 speeds.

USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer rates. Disabling High-Speed USB in the BIOS reverts all USB 2.0 ports to USB 1.1 operation. This may be required to accommodate operating systems that do not support USB 2.0.

NOTE

Computer systems that have an unshielded cable attached to a USB port might not meet FCC Class B requirements, even if no device or a low-speed USB device is attached to the cable. Use a shielded cable that meets the requirements for a full-speed USB device.

Mass Storage Support

The board provides three ATA connectors that can be used to add storage capability to the board. The following connectors are included:

One PATA connector that supports two devices

Two SATA connectors that support one device per connector

PATA Interface

The ICH7-M’s PATA controller has one bus-mastering PATA interface that is accessible through a 44-pin connector that is compatible with 2.5 or 3.5 inch PATA hard drives (including power support for 2.5 inch hard drives). The PATA interface supports the following modes:

Programmed I/O (PIO)

8237-style DMA

Ultra DMA

ATA-66

ATA-100

NOTE

ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections, noise, and inductive coupling.

The PATA interface also supports ATAPI devices (such as CD-ROM drives) and ATA devices using the transfer modes.

The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate and translation mode to the BIOS.

D945GSEJT specifications

The Intel D945GSEJT is a compact motherboard designed for use in embedded systems and low-power computing applications. Released as part of Intel's 945GSE chipset family, it is equipped with a range of features and technologies that cater to the growing demand for efficient computing solutions.

At the heart of the D945GSEJT is the Intel Atom N270 processor, which operates at a frequency of 1.6 GHz. This processor is known for its low power consumption, making it an excellent choice for devices that require continuous operation without significant energy demands. The D945GSEJT operates with a thermal design power (TDP) of merely 5 watts, allowing it to run quietly and efficiently, thus extending the lifespan of the device.

In terms of memory support, the D945GSEJT features two DIMM slots that can accommodate up to 2 GB of DDR2 SDRAM. This enables adequate multitasking capabilities, allowing the system to run multiple applications simultaneously without performance degradation. Additionally, the motherboard supports a memory speed of 533 MHz and 667 MHz.

One of the key characteristics of the D945GSEJT is its integrated graphics capability, featuring the Intel Graphics Media Accelerator 950. This technology supports resolution up to 2048 x 1536 at 75Hz, making it suitable for basic graphical tasks such as web browsing and video playback. The inclusion of an array of output options like LVDS, VGA, and TV-out enhances its versatility for various display needs.

The D945GSEJT also boasts a variety of I/O ports, including six USB 2.0 ports, a parallel port, a serial port, and multiple audio connectors. This wide array of connectivity options allows users to attach peripherals like printers, keyboards, and external audio devices easily.

Moreover, the motherboard includes support for Intel’s SpeedStep technology, which dynamically adjusts processor voltage and frequency, helping to optimize power consumption based on workload demands. This capability is essential for embedded systems where power efficiency is paramount.

To summarize, the Intel D945GSEJT is a robust motherboard that combines efficient processing power with a compact footprint. Its main features include support for low power consumption via the Atom N270 processor, integrated graphics, adequate memory options, and a wide range of I/O ports. These traits make it an ideal choice for embedded applications, digital signage, and other compact computing environments.
