7. Click the Finish button to complete the installation process.
8. Restart your system using one of these methods:
• Select YES at the last screen. The Installation program restarts your system.
• Select NO to manually restart your system at a later time.
Note
You must restart your system before running INtime software.
Installing hardware for use with the RT kernel
Before loading an application to interface with a hardware device, you must make the
hardware available to the RT kernel.
Windows Plug-and-Play software tries to automatically configure hardware it detects at
boot time. To prevent this, INtime provides a Windows driver which causes Windows
to believe it has claimed the hardware while isolating it from other Windows hardware
so that an RT application can interact with it.
In an INtime system it is necessary to separate the IRQs of devices that that INtime will
control from those controlled by Windows. If real-time and Windows devices shared
the same interrupt line, deterministic handling of that interrupt is lost, since release of
that signal would depend on the Windows kernel.
The INtime Device Configuration tool reserves hardware devices for INtime usage. To
run the tool, go to Control Panel>INtime>Device Configuration. Use the tool to select
which devices to reserve for INtime. The tool then analyzes the IRQ resources and
ensures that the allocation is possible.
In cases where you cannot physically isolate the device, the hardware/motherboard
combination in your system is not suitable for running the INtime device driver.
In the case where your device does not generate an interrupt or it supports the MSI
method of interrupt delivery, you can pass the device to INtime by selecting the “No
Interrupt or MSI” option. In this case, interrupt conflict is not an issue.
To install two real-time devices, configure both devices at the same time with the
Device Configuration tool. It ensures that IRQ resources are not shared with Windows,
but allows INtime devices to share the same IRQ when necessary.
