System Board 4-9System Board ComponentsComponent FunctionWinbond Super I/O W83627HF-AW controllerThe controller supports the following:Industry-standard floppy controllerMultimode parallel portCentronics compatible (standard mode)Enhanced capabilities port (ECP)Enhanced parallel port (EPP)Two RS-232C serial portsTwo USB portsIntegrated PS/2 keyboard and mouse controllerOne MIDI/Game portHardware monitorYamaha Sound YMF 752-S Audio integrated on system board, compatible withWindows Sound SystemProcessor and Secondary CacheThe system uses a Pentium III processor with an internal clock speed of 533 MHz or higher(depending on type of processor).The processors are advanced pipelined 32-bit addressing, 64-bit data processors designed tooptimize multitasking operating systems. The 64-bit registers and data paths support 64-bitaddresses and data types.To use the processor’s power, the system features an optimized 64-bit memory interface and256 KB of secondary write-back cache on the processor.The processor is compatible with 8-, 16-, 32-, and 64-bit software written for the Intel386™,Intel486™, Pentium, Pentium II, and Pentium III processors. The processor is installed in aSocket 370 on the system board.System BIOSThe PCI-compatible BIOS is contained in a 4-Mb flash memory device on the system board.The BIOS provides Power-On Self-Test (POST), system Setup program, PCI auto-configurationutility, and BIOS recovery code.The FLASH ROM allows fast, economical BIOS upgrades. The FLASH ROM is areprogrammable EPROM containing both the system and video BIOS. Using the FLASH ROMto change the ROM BIOS provides the following advantages:! BIOS upgrade is performed quickly and easily! expense of replacing ROM BIOS chips is eliminated, so system maintenance costs arereduced! less chance of inadvertently damaging the system board than when physically replacingROMs! network administrators can exercise company-wide control of BIOS revisions.The BIOS programs execute the Power-On Self-Test (POST), initialize processor controllers,and interact with the display, diskette drive, hard drives, communication devices, andperipherals. The system BIOS also contains the Setup Utility.
