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; 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
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.
