System trace information was not specified in your CONFIG.SYS file, or tracing is disallowed.

Updated: Feb 21, 2026

Technical Meaning

The error ERROR_SYSTEM_TRACE with the numeric code 150 and hex code 0x96 indicates that system trace information was not specified in the CONFIG.SYS file, or tracing is disallowed.

Error Details

This error typically arises when the system configuration does not include necessary settings for enabling detailed trace logging. Trace logging can be crucial for diagnosing and troubleshooting issues within the operating system, but it must be explicitly enabled through specific configurations in the CONFIG.SYS file.

Usage Context

The context in which this error occurs is primarily related to system initialization and configuration. It affects scenarios where detailed tracing information is required, such as during kernel debugging or when diagnosing complex issues that require a deeper understanding of system behavior.

Developer Interpretation

Developers should interpret this error as an indication that the necessary trace settings are missing or incorrect in the CONFIG.SYS file. This can lead to reduced diagnostic capabilities and may impact the ability to gather detailed information about system operations, particularly during critical initialization phases.

Related Errors

  • ERROR_TRACE_DISABLED: Indicates tracing is globally disabled.
  • ERROR_CONFIG_FILE_NOT_FOUND: Occurs when the CONFIG.SYS file cannot be found or accessed.

FAQ

Q: What does ERROR_SYSTEM_TRACE mean?

A: It indicates that system trace information was not specified in the CONFIG.SYS file, or tracing is disallowed.

Q: How can I resolve this error?

A: Ensure that the necessary trace settings are correctly configured in the CONFIG.SYS file. Consult the documentation for specific configuration requirements and ensure that tracing is enabled where needed.

Summary

The ERROR_SYSTEM_TRACE 150 (0x96) error highlights a missing or incorrect configuration setting in the CONFIG.SYS file, which can impact system trace capabilities. Developers should carefully configure this setting to enable detailed diagnostics when required.
