10 South bridge controller. Referred to as the Intel I/O Controller Hub 2 (ICH2) of the Intel 845 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. 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 Super I/O chipset. 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. 15 ASUS ASIC. This chip performs multiple system functions that include hardware and system voltage monitoring, IRQ routing, among others. 16 LAN/SCSI slot. This ASUS proprietary slot supports the ASUS LS99 LAN/SCSI card that allows you to connect up to 30 SCSI devices, and hook your PC to a network. 17 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. 18 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. 19 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. 20 Audio/Modem CODEC. This AC '97 compliant audio CODEC supports SPDIF Out feature. 1-6 Chapter 1: Product introduction
