The <strong>RTD</strong> Enhanced AMI BIOS<br />
The <strong>RTD</strong> Enhanced AMI BIOS is software that interfaces hardware-specific features of the cpuModule to an<br />
operating system (OS). Physically, the BIOS software is stored in a Flash EPROM on the cpuModule. Functions of<br />
the BIOS are divided into two parts.<br />
The first part of the BIOS is known as POST (power-on self-test) software, and it is active from the time power is<br />
applied until an OS boots (begins execution). POST software performs a series of hardware tests, sets up the<br />
machine as defined in Setup, and begins the boot of the OS.<br />
The second part of the BIOS is known as the CORE BIOS. It is the normal interface between cpuModule hardware<br />
and the OS which is in control. It is active from the time the OS boots until the cpuModule is turned off. The<br />
CORE BIOS provides the system with a series of software interrupts to control various hardware devices.<br />
Configuring the <strong>RTD</strong> Enhanced AMI BIOS<br />
The cpuModule Setup program allows you to customize the cpuModule's configuration. Selections made in<br />
Setup are stored on the board and are read by the BIOS at power-on.<br />
Entering the BIOS Setup<br />
You can run Setup by rebooting the cpuModule and repeatedly pressing the Delete key. When you are finished<br />
with Setup, save your changes and exit. The system will automatically reboot<br />
