1.1. Explanation of Bug Check

A bug check, often recognized by the colloquial term ‘Blue Screen of Death’ (BSOD), is a self-protective mechanism designed into the Windows operating system. It activates to prevent severe damage due to hardware or software errors. These errors are not merely simple issues; rather, they exhibit potential threats to fundamental system processes, prompting an immediate halt of operations. In such a scenario, the OS triggers a Bug Check 0x9: IRQL_NOT_GREATER_OR_EQUAL with an objective to prevent any further damage

1.2. Definition of IRQL_NOT_GREATER_OR_EQUAL

IRQL_NOT_GREATER_OR_EQUAL, represented by the error code ‘0x9’, is a type of bug check that executes when the system’s Kernel-mode driver accesses invalid or inappropriate memory at high interrupt request level (IRQL). This access attempt leads to critical errors as, at high IRQLs, only specific kinds of kernel mode operations are allowed.

This high interrupt mode mostly blocks access to the paging operation hence, by attempting to access paged memory at such a high IRQL, an access error is triggered. It compels the system to terminate ongoing processes and display the bug check on the screen instead, signifying a status of IRQL_NOT_GREATER_OR_EQUAL.

1.3. Explanation on the Relevance and Implications of the Bug Check

The Bug Check 0x9: IRQL_NOT_GREATER_OR_EQUAL holds vital importance for the overall system functioning and stability. It primarily acts as an early warning system for critical error detection.
