One of the many advantages of free operating systems, as typified by Linux, is that their internals are open for all to view.The operating system, once a dark and mysterious area whose code was restricted to a small number of programmers, can now be readily examined, understood, and modified by anybody with the requisite skills. The Linux kernel remains a large and complex body of code, however, and would-be kernel hackers need an entry point where they can approach the code without being overwhelmed by complexity. Device drivers take on a special role in the Linux kernel.The Microsoft Windows XP Professional operating system provides features that simplify installing, configuring, and managing computer hardware.Plug and Play is a feature that automatically configures devices, loads device drivers, and works with other Plug and Play devices to allocate resources, all without user intervention. A: To determine if your computer is using IRQ Steering, follow these steps: 1. Click Start, point to Settings, click Control Panel, and then double-click System. 2. Click the Device Manager tab. 3. Double-click the System Devices branch. 4. Click on the " " beside "System Devices" 5. Double-click PCI Bus. This will open PCI Bus Properties. The third tab inside of"PCI Bus Properties" is "IRQ Steering". Click on the "IRQ Steering". The bottom half of "IRQ Steering" has four listings: a) IRQ Routing Enabled b) IRQ read from (where it is read from) c) IRQ mini-port loaded successfully d) IRQ mini-port Data Processed successfully. Q: I've tried enabling the IRQ steering checkbox, but it still says, "IRQ Steering disabled". A: IRQ Steering may be disabled for any of the following reasons: - The IRQ routing table that must be provided by the BIOS to the operating system may be missing or contain errors. The IRQ routing table provides information on how the motherboard is configured for PCI IRQ's. Z= - The "Use IRQ Steering" check box is not selected. - The "Get IRQ table from Protected Mode PCIBIOS 2.1 call" check box is not selected. - Your computer's BIOS may not support PCI bus IRQ steering. For more information, contact the manufacturer of your BIOS. For more information on the subject of IRQ Steering, please refer to the Microsoft article at: Q: How do I know if the AMD IRQ Driver is running?This utility displays the processor signature, approximate speed, L1/L2 cache sizes, processor revision, and instruction extensions supported. Usage: Run the executable to display the CPU information for AMD processors. The accuracy of the utility on non-AMD processors is not guaranteed. The utility will work in pure DOS, a DOS box under Windows,&... A: Under the "Control Panel, System properties, Device Manager" tab, a PCI based card may be listed as not working properly. The following message is in the Device status area of the device's properties: "This device is disabled because the BIOS for the device did not give it an IRQ (Interrupt Request). Code 29". This is an instance when the AMD IRQ Driver should be used. Q: Why else might I need to install the driver? A: Under the "Control Panel, System properties, Device Manager" tab, the PCI bus device has IRQ steering disabled. IRQ steering information is a tab under the PCI bus properties. The IRQ Routing Status describes that IRQ table was read, IRQ miniport data was processed successfully and an error was encountered with the IRQ Miniport. Q: How do I know if IRQ Steering is enabled on my system?

The only file required in this configuration is the main application file Maestro does not come packaged with an installer utility, but setting up the program itself is simply a matter of copying the required files to a selected directory in the host system and making one change in the Windows registry.
In order to run experiments, of course, you will need to install the RTX runtime environment and all of the required hardware, but you need not install the drivers for these devices.
