South bridge controller. The fourth-generation Intel I/O Controller
Hub (ICH4) is a subsystem that integrates various I/O functions
including 2-channel ATA/100 bus master IDE controller, up to six USB
2.0/1.1 ports, I/O APIC, SMBus 2.0 controller, LPC interface, AC’97 2.2
interface, and PCI 2.2 interface. The ICH4 also contains the necessary
arbitration and buffering for efficient utilization of these interfaces.
Serial ATA connectors. These two 7-pin connectors accommodate
the thin cables for Serial ATA devices.
Speech controller. This Winbond speech controller supports the
ASUS POST Reporter™ for configurable vocal POST alerts.
Flash ROM. This 4Mb firmware contains the programmable BIOS
program.
RAID IDE/Serial ATA controller. The Promise
®
PDC20376 RAID IDE
and Serial ATA controller provides high performance RAID 0/RAID 1
functionality and supports the Serial ATA solution.
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.
ASUS ASIC. This chip performs multiple system functions that include
hardware and system voltage monitoring, IRQ routing, among others.
Super I/O controller. This 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, a Standard Infrared (SIR), and a Flash ROM interface.
IEEE 1394 controller. The VIA VT6307 controller chipset supports
two low power IEEE 1394 connectors to allow 100Mbps, 200Mbps,
and 400Mbps data transfers between the PCI bus and the 1394 bus.
PCI slots. These six 32-bit PCI 2.2 expansion slots support bus
master PCI cards like SCSI or LAN cards with 133MB/s maximum
throughput. The ASUS proprietary BlueMagic PCI slot (blue slot)
supports future ASUS function cards compliant to PCI specification.
Audio CODEC. The ADI AD1980 is an AC’97 CODEC that allows
6-channel audio playback. The audio CODEC provides six DAC
channels for 5.1 surround sound, S/PDIF output, AUX and Line In
stereo inputs, integrated headphone amplifier, greater than 90dB
dynamic range, and stereo Mic PREAMP support.
