SUMMARY

There is additional Network Driver Interface Specification (NDIS) debugging information available in Windows 98 and Windows 98 SE. This article describes how to access that additional information using the global symbols, ndisdebuglevel and ndisdebugsystems.

MORE INFORMATION

Listed below are level and component NDIS debugging flags. These flags are set through the debugger, and provide trace information as execution passes through NDIS. These flags can be ORed together.

Execute the WDEB386 or WDEB98 debugger with the /B option to break the debugger after driver loading finishes and before VMM initialization begins. At the break, set the NDIS trace important flag, and go: 
e ndistraceimpt 1
After returning from WrapperSyCriticalInit, break into the system and set the ORed value of the trace information in which you are interested. Enter the ORed value in Intel byte order. Use of these flags requires the Windows 98/SE debug binary version of the Ndis.vxd device driver.

EXAMPLE: Set the level trace information for ERROR in the debugger in the following manner: 
e ndisdebuglevel 00 20 00 00
Level Descriptions Value
INFORMATION 0x00000000
LOG 0x00000800
WARNING 0x00001000
ERROR 0x00002000
FATAL 0x00003000


EXAMPLE: Set the component trace information for RECEIVE and SEND in the debugger in the following manner: 
e ndisdebugsystems 0C 00 00 00
