USB 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 boards support up to seven USB 1.1 ports via the ICH2 and I/O controller; four ports routed to
the back panel, two to the front panel connector, and one to the optional CNR. To attach additional
devices, connect an external hub to either of the built-in ports. The board supports the standard
universal host controller interface (UHCI) and takes advantage of standard software drivers written
to be compatible with UHCI.
PCI Enhanced IDE Interface
The ICH2s 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 four IDE devices (such as hard drives)
ATAPI devices (such as CD-ROM drives)
PIO Mode 3 and PIO Mode 4 devices
