FEATURES OF THE BOARD

Overview
Congratulations on purchasing the highest performance Pentium motherboard. With the advanced technologies available today, this motherboard is designed to run Intels Pentium processors at speeds up to 233 MHz. The on-board system memory consists of SIMM and DIMM that gives you the most flexibility for system design. It supports up to 256 MB of DRAM using standard 72-pin SIMM sockets that accept either Fast Page Mode (FPM) and Extended Data Out (EDO) memory. In addition, two unbuffered, 3.3 Volts, 168-pin SDRAM sockets are also included for up to 256MB Synchronous Dynamic Memory support. A 321-pin, type 7, Zero Insertion Force (ZIF) socket allows an easy upgrade path for the future Pentium Overdrive processors. This motherboard utilizes Intel's 82430TX PCI chipset. The Intel 82371AB PCI/ISA IDE Xccelerator (PIIX4) provides an integrated Bus Mastering IDE controller with two high performance IDE interfaces for up to four IDE devices (such as hard drives or CD-ROM) and Ultra 33 Synchronous DMA mode transfers up to 33Mbytes/sec. The integrated I/O controller integrates the standard PC I/O functions: floppy interface, two FIFO serial ports, one EPP/ECP capable parallel port, and support for an IrDA and Consumer Infra Red compatible interface. The three on-board 32-bit PCI local bus slots allows a higher bandwidth data path, which serves as a super highway, for intensive data-movement such as video or networking. The BIOS support PCI bridge user configuration, which allows for further expansion of the system with PCI peripherals. And the three 16-bit ISA slots allow this board backward hardware compatible with the older expansion card. A total of six expansion slots may be populated with full lengths add-in cards, since one PCI and ISA slot share the same chassis I/O panel.

Auto Jumper Yes

This motherboard (5STX-J98) is one of our Auto Jumper Yes series, which eliminates the necessity for the user to be bored by jumper settings on the motherboard. It is capable of detecting the CPU brand, and setting the appropriate CPU core voltage and speed according to instructions from the user through CMOS setup menu. In contrast to Jumperless, Auto Jumper Yes allows switching to manual mode that enables physical jumpers on the mainboard, so as to prevents the potential impacts on jumperless boards from future CPU specifications. On the other hand, pressing F to clear CMOS setting and J to re-detect CPU during power on the system, to avoid the difficulties to reset the CMOS data.

GETTING START

All computer motherboards provide a Setup utility program for specifying the system configuration and settings. If your motherboard came in a computer system, the proper configuration entries may have already been made. This motherboard has been programmed with Award BIOS setup utility. The setup utility program is stored inside the on-board programmable Flash ROM chip. This Setup program allows user to modify the basic system configuration. The system configuration is stored in the battery backup CMOS RAM (inside the real time clock chip) so that it retains the setup information when the power is turned off. This chapter explains the setup utility for the Award BIOS.

ENTERING SETUP
