The checked build of the Network Driver Interface Specification (NDIS) driver in Microsoft Windows Millennium Edition contains debugging options that you can enable in the registry to produce additional kernel debug output. This article describes how to install the checked build of Ndis.vxd and how to enable additional trace information.
Install the Windows Millennium Edition kernel debugger according to the instructions in the Driver Development Kit (DDK).
Download the check build NDIS binaries from the following Microsoft Knowledge Base article:
241517 Ndis.exe Windows Millennium Edition NDIS debug binaries
You must disable System File Protection (SFP) before you copy the checked build of Ndis.vxd to the Windows\System folder. You can do this by starting from the Microsoft Windows 98 startup floppy or by starting the system in safe mode. SFP is disabled in safe mode. To start in safe mode, press F8 when Windows Millennium Edition starts, and then select Safe Mode from the menu of boot options.
Note Please be aware that these values differ from similar lists in other versions of Microsoft Windows. Specifically, the list in the following Microsoft Knowledge Base article, which describes NDIS debugging for Microsoft Windows 98:
These values can be ORed together to specify multiple components. By default, the following components are pre-selected when TraceImpt is enabled:
DebugLevel: DebugLevel allows you to adjust how much trace information is emitted. INFO level produces the most information, and it is the default value if TraceImpt is enabled. Otherwise, its default value is FATAL. Possible values are:
INFO 0x00000000LOG 0x00000800WARN 0x00001000ERR 0x00002000FATAL 0x00003000
NdisTraceAll is a flag, which, if enabled, produces very verbose trace information. It cannot be enabled through a registry entry. You may enable it by causing NDIS to break at startup by using the DebugBreak option, described previously. When NDIS hits the breakpoint, load NDIS' symbols and then set ndistraceall:wa ndis e ndistraceall 1
