1.1 Introduction 8355 N/B MAINTENANCE 1. Hardware Engineering Specification The 8355 motherboard would support the AMD ClawHammer K8 processor with uPGA Package, 2700+/3000+/3300+/3600+/3900+/4200+, FSB 800MHz This system is based on PCI architecture, which have standard hardware peripheral interface. The power management complies with Advanced Configuration and Power Interface (ACPI) 2.0. It also provides easy configuration through CMOS setup, which is built in system BIOS software and can be pop-up by pressing F2 at system start up or warm reset. System also provides ico LEDs to display system status, such as AC Power, Battery Power, Battery status, CD- ROM, HDD, NUM LOCK, CAP LOCK, SCROLL LOCK, WIRELESS LAN status. It also equipped 4 USB2.0 ports. The memory subsystem supports 0MB on board; Expandable up to 1024MB Expandable with combination of optional 128/256/512 MB memory 200-pin DDR 266/333/400 Memory Module x2, PC-2100/2700/3200 specification The K8T800 North Bridge plus VT8235 South Bridge chipset is a high performance, cost-effective and energy efficient solution for the implementation of desktop personal computer systems with 8 / 16-bit 800 / 600 / 400 / 200 MHz HyperTransport. CPU host interface based on AMD K8 / ClawHammer. processors. The VT8235 “V-Link Client Controller” is a highly integrated PCI /LPC controller. Its internal bus structure is based on a 66 MHz PCI bus that provides 2x bandwidth compared to previous generation PCI bridge chips. The VT8235 also provides a 533 MB/sec bandwidth Host / Client V-Link interface with V-Link-PCI and V-Link-LPC controllers. It supports six PCI slots of arbitration and decoding for all integrated functions and LPC bus. 4
