Intel Desktop Board D915GMH Product Guide Table 6 describes the LED states when the board is powered up and the 10/100/1000 Gigabit Ethernet LAN subsystem is operating. Table 6. RJ-45 10/100/1000 Gigabit Ethernet LAN Connector LEDs LED Color Bi-color LED Green LED State Off Green Yellow Off On (pulsing) Indicates 10 Mbit/sec data rate is selected. 100 Mbit/sec data rate is selected. 1 Gbit/sec data rate is selected. LAN link is not established. The computer is communicating with another computer on the LAN. 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 ICH6; 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. Disabling Hi-Speed USB in 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 ICH6'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 via ICH6 connecting one device per channel. 18

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 ICH6; 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.
Disabling Hi-Speed USB in 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 ICH6’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 via ICH6 connecting one device per channel.
