Trinity ATX (S1592) Quick Setup Guide

The table below will help you set the jumpers for CPU speed, bus frequency, and memory voltage,among others.

*  This motherboard incorporates support for 75 MHz and 83 MHz BUS speeds.  However, these speeds will push PCI bandwidth beyond the Intel recommended specification for PCI 2.1 compliance.  Therefore, TYAN Computer Corporation takes no responsibility for any problems, be it hardware or software, related to the use of BUS speeds beyond 66MHz. We also cannot guarantee any PCI cards' compatibility beyond the specified speed of 33MHz.  Technical support and RMA / Warranty claims relating to the use of BUS speeds beyond the 66 MHz  / 33 MHz limit recommended by Intel will not be honored by TYAN.  USE AT YOUR OWN RISK.

** The JPW1 setting for the Cyrix 6x86L series will vary.  Some of the CPUs in this series are 2.8V, and others are 3.3V.  Check the face of the CPU and the CPU Voltage Settings table for the proper settings for these jumpers.
