IDE connectors. These dual-channel bus master IDE connectors support
Ultra DMA/100/66, PIO Modes 3 & 4 IDE devices. Both the primary (blue)
and secondary (black) connectors are slotted to prevent incorrect insertion
of the IDE ribbon cable.

Floppy disk connector. This connector accommodates the provided
ribbon cable for the floppy disk drive. One side of the connector is slotted
to prevent incorrect insertion of the floppy disk cable.

Standby power LED. This LED lights up if there is a standby power on
the motherboard. This LED acts as a reminder to turn off the system
power before plugging or unplugging devices.

Speech controller. This Winbond speech controller supports the
ASUS POST Reporter™ for configurable vocal POST alerts.

IEEE 1394 controller. The TI TSB43AB22A chipset supports two low
power IEEE 1394 connectors to allow 100Mbps, 200Mbps, and
400Mbps data transfers between the 1394 devices.

South bridge controller. The fifth-generation Intel I/O Controller Hub
(ICH5R) is a subsystem that integrates various I/O functions including
2-channel ATA/100 bus master IDE controller, SATA RAID controller, up
to eight USB 2.0/1.1 ports, I/O APIC, LPC interface, AC’97 2.3 interface,
and PCI 2.2/2.3 interface. The ICH5 also contains the necessary
arbitration and buffering for efficient utilization of these interfaces.

RAID/SATA/IDE controller. The Promise

PDC20378 RAID controller

provides high-performance RAID0/RAID1/RAID0+1 functionality and
complies with the Serial ATA and UltraDMA 133 specifications.

PCI slots. These 32-bit PCI 2.3 expansion slots support bus master
PCI cards like SCSI or LAN cards with 133MB/s maximum throughput.

Super I/O controller. This Winbond Low Pin Count (LPC) interface
provides the commonly used Super I/O functionality. The chipset supports
a high-performance floppy disk controller for a 360K/720K/1.44M/2.88M
floppy disk drive, a multi-mode parallel port, two standard compatible
UARTs, and a Flash ROM interface. This controller also integrates the
ASIC for PC health monitoring.

Audio CODEC. The AD1985 AC ‘97 2.3 stereo audio CODEC provides
a 6-channel audio capability. The CODEC supports surround sound
output, variable sample rate conversion, analog enumeration
capability, and other major audio technologies for a complete
integrated audio solution.
