The STOP Message Screen

Character-mode STOP messages are always displayed on a full character-mode screen rather than in a Windows-mode message box. They are also uniquely identified by a hexadecimal number and a symbolic string, as in the following example:

*** STOP: 0x00000001
APC_INDEX_MISMATCH

The content of the symbolic string may suggest, to a trained technician, which part of the Kernel detected the condition that left no recourse but to stop. However, keep in mind that the cause may actually be in another part of the system.

Figure 38.1 is an example of a complete STOP message screen generated by the Windows NT Kernel.
