  • Page 7: Chapter 1 Introduction

    Introduction Overview AMI EZ-Flex takes a modular approach to CPU selection. Using EZ-Flex, a system is never outdated and the user is always assured of an upgrade path. Traditional systems place all system parts, including the CPU, math coprocessor, and ROM BIOS, on the motherboard, which makes it difficult to change the basic system configuration.
  • Page 8 Overview, Continued EISA Standards The AMI EZ-Flex is fully compatible with both EISA and ISA specifications and can run on either 80386, 80486SX, or 80486-based systems, and needs no major architectural changes to run on more advanced Intel microprocessors as they become available.

  • Page 9: Bios Features

    CMOS RAM The AMI EZ-Flex BIOS Setup configuration settings are saved in the 64 bytes of CMOS RAM on the EZ-Flex Base Board. CMOS RAM and the clock and calendar are powered by a built-in battery in the RTC/CMOS chip itself.

  • Page 10: I/O Features

    I/O Features Built-in I/O The EZ-Flex system contains built-in input/output controllers to save both money and system setup time. The controllers can be configured by the AMI EISA BIOS Setup. The controllers include: • two serial ports, which are software-configurable for COM 1, COM2, COM3, or COM4, or can be disabled by the EISA Configuration Utility (ECU).
