Hi all,

I have a problem,can you please help me out? We want boot zImage(zImage is comprised of EFI stub and Linux kernel) by Tftp in Bootmanager,but we found an error:

The error happened in BdsLoadImage-> BdsConnectDevicePath.Actually, Handle is no use in BdsTftpLoadImage,so I modify BdsLoadImage for test,then we can download zImage,but we still cannot boot it; (We can boot linux by Grub)

Can you give me some advice?
