12 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. 13 IEEE 1394 controller. The TI TSB43AB22 controller chipset supports two low power IEEE 1394 connectors to allow 100Mbps, 200Mbps, and 400Mbps data transfers between the 1394 devices. (on 1394 models only) 14 Serial ATA/RAID controller. The Silicon Image Sil3112A controller provides high-performance RAID 0/RAID 1 functionality and complies with the Serial ATA specification. 15 Flash ROM. This 4Mb firmware contains the programmable BIOS program. 16 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. 17 Audio CODEC. The RealTek ALC650 AC '97 2.2 stereo audio CODEC provides a 6-channel audio capability. The ALC650 supports independent variable sampling rates and built-in 3D effects, mono outputs, multiple stereo and mono inputs, and flexible mixing/gain/mute functions for a complete integrated audio solution. (on audio models only) 18 PCI slots. These five 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. 19 Super I/O controller. This Low Pin Count (LPC) interface provides the commonly used Super I/O functionality. The chipset supports a highperformance 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. 20 AGP warning LED. Serving as a smart burn-out protection for the motherboard, this red LED lights up if you plug in any 3.3V AGP card into the AGP slot. When this LED is lit, there is no way you can turn on the system power even if you press the power button. ASUS P4G8X series motherboard user guide 1-9
