  • Page 83: The Rtd Enhanced Award Bios

    The RTD Enhanced Award BIOS The RTD Enhanced Award BIOS (Basic Input/Output System) is software that interfaces hardware- specific features of the cpuModule to an operating system (OS). Physically, the BIOS software is stored in a Flash EPROM on the cpuModule. Functions of the BIOS are divided into two parts: The first part of the BIOS is known as POST (Power-On Self-Test) software, and it is active from the time power is applied until an OS boots (begins execution).

  • Page 84: Direct Hardware Control

    Some of the cpuModule hardware is controlled directly without using BIOS routines. These include: • Advanced Digital I/O (aDIO) • Watchdog Timer • Real Time Clock Control • Parallel Port Control The following sections describe use of these features. CME37786HX RTD Embedded Technologies, Inc.

  • Page 85: Advanced Digital I/O Ports (Adio)
