FIX: The NDIS driver may not load, or an unhandled exception may occur in Windows CE .NET 4.2 (840880)


The information in this article applies to:

  • Microsoft Windows CE .NET 4.2

SYMPTOMS

The network driver may not load. This problem occurs when the I/O memory address range causes the VirtualCopy function in Network Driver Interface Specification (NDIS) to fail. The I/O memory address range is returned by the Personal Computer Memory Card International Association (PCMCIA) card service. This problem occurs on a non-x86 microprocessor that supports bus I/O.

Additionally, an unhandled exception may occur in Device.exe. The unhandled exception may occur when the NdisOpenFile function is used. The problem may more frequently occur after you apply the 812950 hotfix.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

This update introduces a registry setting that changes how NDIS handles I/O address range mapping. The default is as follows:
  • Memory mapped I/O for all non-x86 architecture processors
  • Bus mapped I/O for all x86 architecture processors
For memory mapped I/O, see the following code example.

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\NDIS]
	"NeedsMapToScrap"=dword:1		; any non-0 value
For bus I/O, see the following code example. 
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\NDIS]
	"NeedsMapToScrap"=dword:0

For example, on an Intel IXP4xx microprocessor, the operating system default setting is memory mapped I/O. However, this microprocessor supports bus I/O. Therefore, NeedsMapToScrap must be set to 0.
