10 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), one MPU-401 UART mode compatible MIDI/game port, and a Flash ROM interface. 11 DIP switches. This 10-switch Dual Inline Package (DIP) allows you to set the CPU external frequency. 12 Speech controller. This Winbond speech controller supports ASUS POST Reporter™ for configurable vocal POST alerts. 13 Flash EEPROM. This 2Mb firmware contains the programmable BIOS program. 14 South bridge controller. Referred to as the Intel I/O Controller Hub 2 (ICH2) of the Intel 845D chipset, this controller provides the I/O subsystem that allows access to the rest of the system. The ICH2 integrates I/O functions such as system bus interface, Ultra ATA/100, Low Pin Count (LPC) interface, Universal Serial Bus (USB) 1.1 interface, PCI interface, and CNR interface. 15 ASUS ASIC. This chip performs multiple system functions that include hardware and system voltage monitoring, IRQ routing, among others. 16 USB 2.0 controller. This controller supports the Universal Serial Bus (USB) 2.0 specification for a fast connection speed of up to 480 Mbps, thus allowing more functionality and higher performance for PC peripherals. (optional) 17 Onboard LED. This onboard 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. 18 CNR slot. This slot is specifically designed for the Communications and Networking Riser (CNR) card. The CNR supports V.90 analog modem, six-channel audio, HPNA, USB Hub, and the 10BASE-T/ 100BASE-TX Ethernet networking. 19 Audio controller. This C-Media 6-channel PCI audio chip supports legacy audio and HRTF 3D positional audio functions. The chip also supports 24-bit S/PDIF In (0.5~5V) and S/PDIF Out (44.1K and 48K formats) professional digital audio interface. (on audio models only) ASUS P4B266 motherboard user guide 1-7
