RJ-45 LAN Connector LEDs
Two LEDs are built into the RJ-45 LAN connector. The following table describes the
LED states when the board is powered up and the LAN subsystem is operating.

Universal Serial Bus (USB)
The motherboard has four USB ports and a further five can be added via internal
headers; one USB peripheral can be connected to each port. For more than nine
USB devices, an external hub can be connected to either port. The motherboard
fully supports the universal host controller interface (UHCI) and uses UHCI-
compatible software drivers.
USB features include:
Self-identifying peripherals that can be plugged in while the computer is
running.
Automatic mapping of function to driver and configuration.
Supports isochronous and asynchronous transfer types over the same set of
wires.
Supports up to
127
physical devices.
Guaranteed bandwidth and low latencies appropriate for telephony, audio,
and other applications.
Error-handling and fault-recovery mechanisms built into the protocol.
NOTE:
Computer systems that have an unshielded cable attached to a USB port
may not meet FCC Class B requirements, even if no device or a low-speed (sub-
channel) USB device is attached to the cable. Use shielded cable that meets the
requirements for high-speed (fully rated) devices.
IDE Support
The motherboard has one independent bus-mastering PCI IDE interfaces. These
interfaces support PIO Mode 3, PIO Mode 4, ATAPI devices (e.g., CD-ROM), Ultra
DMA/66 & Ultra DMA/100 synchronous-DMA mode transfers. The BIOS supports
logical block addressing (LBA) and extended cylinder head sector (ECHS)
translation modes. The BIOS automatically detects the IDE device transfer rate and
translation mode.
Programmed I/O operations usually require a substantial amount of processor
bandwidth. However, in multitasking operating systems, the bandwidth freed by bus
mastering IDE can be devoted to other tasks while disk transfers are occurring.
