C h a p t e rC h a p t e r11System BoardSystem Board 1-11.1 FeaturesThis high-performance system board supports the Intel Pentium II CPUrunning at 233/266/300 MHz. Designed to work with Intel 440LX systemcontroller, which consists of the PCI/AGP controller (PAC) and the PCI/ISAIDE accelerator (PIIX4), the CPU carries a new generation of power.The PAC host bus interface supports up to two Pentium II processors with66 MHz bus frequency. It also provides a 72-bit DRAM support using bothextended data output (EDO) and synchronous DRAM (SDRAM) DIMMs.The PAC introduces a new technology, which is the Accelerated GraphicsPort (AGP) interface. Supporting up to 133 MHz data transfer rate, theAGP interface boosts graphics performance.The PIIX4 is a multifunction PCI device controller implementing systemfunctions including PCI-to-PCI bridge, PCI IDE, universal serial bus (USB)host/hub, and enhance power management. It also supports Ultra DMA/33synchronous DMA-compatible devices.The system board utilizes both the ISA and the PCI local bus architecture.Two ISA and four PCI bus slots (including one PCI/ISA shared slot) resideon the board to allow installation of either master or slave devices.Four memory banks composed of 168-pin dual inline memory module(DIMM) sockets support a maximum system memory of 512 MB using128-MB DIMMs. The sockets support both EDO and SDRAM-typeDIMMs.A 50-pin Fast SCSI-II and a 68-pin Wide SCSI interface come with thesystem board to connect SCSI devices. Standard I/O features such as twoenhanced IDE drive interfaces, two serial interfaces, one parallel portinterface, a diskette drive interface, and PS/2 mouse and keyboardconnectors reside on the system board.The system board supports two optional features, the ASM Pro and theremote diagnostic management (RDM), that allow better server
