Re: Error Loading Kernel



Did you build your own kernel? Did you thin your /mach_kernel file to be 64-bit only on a system that does not support the 64-bit kernel? Are you using a mismatched boot.efi, for instance from Leopard?

A bit of a follow up.

Using otool -h -arch all, I have learned that 0xfeedfacf is the magic
number for x86_64 architectures. I am of course booting Snow Leoapard.

Now I find the message all the more confusing.

I'm trying to work out what files have been corrupted to cause the
error message at boot time:

...Mach-O file has bad magic number 0xfeedfacf
Error loading kernel 'mach_kernel' (0x1)

That's the message I get when booting from a newer MacBook Pro. On
an older Mac Pro, there is an error message and a reboot so I am
unable to read the error message as it flashes by. I do see the Mac
Pro showing more than one row of dots as it is loading. (I've always
assumed that each dot is a kext,)

The corruption was caused by a disk driver that I am working on. I'd
like to work out what the corruption is in order to diagnose the
problem.

Is there some way of determining which file has been corrupted?

I replaced the mach_kernel file already so that's not it.

I suspect that it's one of the kext. But I'm not sure how to
determine if it is corrupted or which one is corrupted. I tried
running "otool -h" on all of the files in MacOS directories, but
they all seem to check out with a proper 0xfeedface.

Is there some other options or some other tools that can help?

Thanks for the help!
