Intel DG35EC Hi-Speed USB 2.0 Support, Enhanced IDE Interface, Serial ATA, LAN Connector LEDs

Desktop Board Features

Table 3 describes the LED states when the board is powered up and the LAN subsystem is operating.

Table 3. LAN Connector LEDs

LED	LED Color	LED State	Indicates
A (Link)	Green	Off	LAN link is not established
		On	LAN link is established
		Blinking	LAN activity is occurring
B (Speed)	N/A	Off	10 Mb/s data rate
	Green	On	100 Mb/s data rate
	Yellow	On	1000 Mb/s data rate

Hi-Speed USB 2.0 Support

The Desktop Board supports up to 10 USB 2.0 ports (six ports routed to the back panel and four ports routed to two internal headers) via ICH8. 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 board’s IDE interface handles the exchange of information between the processor and peripheral devices such as hard disk drives and CD-ROM drives. 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

Serial ATA

The Desktop Board supports four Serial ATA channels (3.0 Gb/s) via ICH8, connecting one device per channel.
