Introduction
1.1 Overview
P5V580 VP3 green mainboard provides a highly integrated solution for fully
compatible, high performance PC/ATX platforms, and supports Intel Pentium
®
,
Cyrix 6x86, 6x86MX and AMD K5, K6 microprocessors. It features Write-Back
Secondary Cache memory for 512KB in size. Flexible main memory size can be
installed from 8MB up to 384MB DRAMs, so as to give full play to the advantages
of the Pentium , Cyrix 6x86, 6x86MX, idt C6 and AMD K5, K6 CPUs. The
mainboard offers a wide range of interface to support integrated on-board IDE and
on-board I/O function. The current green function is compliant to ACPI
specification and OS Directed Power Management.
