The /baseaddress option lets you specify the preferred base address at which to load a DLL. For more information about when and why to use this option, see Improving Application Startup Time and Larry Osterman's WebLog.
The default base address for a DLL is set by the .NET Framework common language runtime.
Be aware that the lower-order word in this address will be rounded. For example, if you specify 0x11110001, it will be rounded to 0x11110000.
To complete the signing process for a DLL, use SN.EXE with the -R option.
