Ashish,

Are you asking for exam= ple code, or reasons that you would not want to enumerate something as boot= able? 

Most likely if you want to = have a platform policy to add gEdkiiSkipBmAutoEnumerateProtocolGuid yo= u are going to need an EFI Driver Model driver to add it to the handle base= d on some platform policy. This is the only way you can filter based on thi= ngs getting connected at different times during boot. 

Thanks,

Andrew Fis= h


Thanks
Ashish

With the UEFI driver model, if a device is no= t needed by booting, it can skip the connecting.
Then I do not see a need of the new protocol.

Thanks,
