BUG: VOLTRACK Is Erroneously Unloaded After 255 Device Additions and Removals


The information in this article applies to:

  • Microsoft Windows 95
  • Microsoft Windows 98
  • Microsoft Windows 98 Second Edition


VOLTRACK is unloaded and may cause Windows to display a blue screen after 255 device additions and removals.


VOLTRACK keeps a count of the number of devices it is attached to in an internal byte-size variable. This variable is incremented in response to a AEP_CONFIG_DCB command, but is not decremented. After 255 additions and removals, the byte overflows and VOLTRACK is unloaded in response to a AEP_BOOT_COMPLETE command from IOS. This can cause driver memory to be overwritten and can cause system instability.


Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.
