site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com Hi, all, I successfully built the latest kernel, xnu-517.9.4. Before actually using it , I need to test whether it works or not.

From some previous threads, I learn that I can change boot-file variable to boot the Mac with my built kernel, but it seems not works.

Here is what I did:

sudo cp <path_to_my_built_kernel>/mach_kernel /mach_kernel.gcc sudo nvram boot-device boot-device hd:,\\:tbxi

sudo nvram boot-file='hd:, mach_kernel.gcc' sudo reboot #the system doesn't come up. reboot the machine, press crt-option-o-f keys, set-defaults /* this reset the boot-file varabile back to its default, which is mach_kernel */ reboot the machine, the system comes up. sudo cp /mach_kernel /mach_kernel_good /* save the currently working kernel */ sudo cp /mach_kernel.gcc /mach_kernel /* rename my built kernel with the default name: mach_kernel */ sudo reboot #the system comes up, so it proves that my built kernel is working.

As a conclusion, it looks like only by changing the boot-file variable name can't boot the system with a kernel having a different name other than mach_kernel. I am wondering has anyone successfully booted a system with a kernel, whose name is not mach_kernel ? If so, could you please provide some insights ? Thanks a lot.
