The RTD Enhanced BIOS
The RTD Enhanced BIOS 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). POST software performs a series of hardware tests, sets up the
machine as defined in Setup, and begins the boot of the OS.
The second part of the BIOS is known as the CORE BIOS. It is the normal interface between cpuModule hardware
and the OS which is in control. It is active from the time the OS boots until the cpuModule is turned off. The
CORE BIOS provides the system with a series of software interrupts to control various hardware devices.
Configuring the RTD Enhanced BIOS
The cpuModule Setup program allows you to customize the cpuModule's configuration. Selections made in
Setup are stored on the board and are read by the BIOS at power-on.
Entering the BIOS Setup through the Graphical BIOS Menu
To launch Setup, apply power or rebooting the cpuModule and repeatedly press the
Escape key
. This will bring
you to a graphical Setup menu with several options described in Table 34, below.
To enter Setup, navigate to select the “SCU” option with the arrow keys, and press Enter .
