1 Introduction The 82430 TX PCI mainboard is a high-performance AT form-factor system board that supports P54C/P55C family CPUs. This mainboard is fully compatible with industry standards, and adds many technical enhancements. Key Features • Processor supported Ä Supports P54C/P55C family CPUs running at 75~233 MHz speeds ;...
Introduction Unpacking the Mainboard The mainboard package contains: ¥ The 82430TX Mainboard ¥ One CD (including Manuals/Drivers/Utilities) Note: Do not unpack the mainboard until you are ready to install it. Follow the precautions below while unpacking the mainboard. Before handling the mainboard, ground yourself by grasping an unpainted portion of the systemÕs metal chassis.
2 Hardware Setup This chapter explains how to configure the mainboardÕs hardware. After you install the mainboard, you can set jumpers, install memory on the mainboard, and make case connections. Refer to this chapter whenever you upgrade or reconfigure your system. CAUTION: Turn off power to the mainboard, system chassis, and peripheral devices before performing any work on the...
Hardware Setup JP43: CPU Cooling Fan Connector This 3-pins connector provides 12V power for the CPU cooling fan which matches the pin assignment of this connector. If you enable the Suspend Mode function in BIOS setup, this fan will stop when the system is into the suspend mode.
CPU Type Configuration This section shows you how to configure your CPU step by step. Note that you need to check the CPU voltage before installation. This mainboard supports 75MHz host bus frequency for Cyrix CPUs. Beware that 75MHz host bus frequency is over the specification of this chipset. Therefore, you have to use high quality devices to meet the standard of these CPUs, i.e., high quality DRAM and VGA card.
Hardware Setup Pentium – 233 CPU Settings (3.5 x clock) AMD K6 – PR233 CPU Setting 82371AB P.B. SRAM 64K x 32 586 CPU Family P.B. SRAM 64K x 32 Figure 2Ð1Ð5. CPU Jumper Settings Note: You must equip the CPU with a fan and heat sink for system stability.
Hardware Setup Step 2: CPU Single/Dual Voltage Setting There are two kinds of CPU input voltages in the marketÑSingle and Dual. Set your CPU according to the type that you have. For Intel P54C/P55C series CPUs, there is no need to adjust any jumper for CPU voltag due to the Smart Detect CPU Voltage function that this board has.
Hardware Setup Dual Voltage CPU Setting Dual voltage CPUs are designed to use different voltage for VIO and VCore. They include P55CX series, Cyrix 6x86L/6x86MX. Refer to the following figures to set teh voltage for these CPUs: 2.1V CPU 82371AB 2.8V CPU (default) P.B.
