Running coLinux on a dual-core system

When running coLinux on a dual-core system, it blue-screens with the DRIVER_IRQL_NOT_LESS_OR_EQUAL error. In order to get around the problem, boot.ini must be modified. Ordinarily, the noexecute option is set to "optin" to indicate that the no-execute protection (also known as Data Execution Protection - DEP) is enabled. While it is useful for preventing malicious code from exploiting buffer overflow bugs, DEP must be disabled to run coLinux on dual-core systems. To do so, select system on the control panel. Click on the Advanced tab. In the "Startup and Recovery" section, click on the "Settings" button. In the "System startup" section, click on the "Edit" button. A notepad with boot.ini will appear. Modify "/noexecute=optin" as "/noexecute=AlwaysOff". Save the change and reboot the system.
