Desktop Board Features

Hi-Speed USB 2.0 Support

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.

The desktop board supports up to eight USB 2.0 ports via ICH7 or ICH7R; four ports routed to the back panel and four routed to two internal USB 2.0 headers. 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 Hi-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.

Enhanced IDE Interface

The ICH7’s IDE interface handles the exchange of information between the processor and peripheral devices like hard disks, CD-ROM drives, and Iomega Zip* drives inside the computer. The interface supports:

Up to two IDE devices (such as hard drives)

ATAPI-style devices (such as CD-ROM drives)

Older PIO Mode devices

Ultra DMA-33 and ATA-66/100 protocols

Laser Servo (LS-120) drives

Serial ATA

The desktop board supports four Serial ATA channels (3.0 Gb/s) via ICH7, connecting one device per channel. Desktop boards with ICH7R support Intel Matrix Storage Technology (NCQ, Hot Plug, RAID 0, 1, 10, 5, and Matrix RAID).

Expandability

The desktop boards support the following:

Desktop board D945GNT:

One PCI Express x16 add-in card

Two PCI Express x1 add-in cards

Four PCI add-in cards

Desktop board D945GTP:

One PCI Express x16 add-in card

One PCI Express x1 add-in card

Two PCI add-in cards
