I assume you've installed the Developers Kit from the 10.2 Disk. Have you installed the darwintools.pkg? It's on Apple's website, follow the links at the Apple Darwin page. I can't remember the path right now, but it's there somewhere. Get a CVS account. To log in to CVS from the Terminal, setenv CVSROOT :pserver:username@anoncvs.opensource.apple.com:/cvs/Darwin cvs login cvs -z3 checkout -r Apple-344 xnu (Apple-344 is the CVS tag, substitute the one you want) Once the download is complete, cd xnu source SETUP/setup.csh make Once the make is complete sudo cp /mach_kernel /mach_kernel_bck sudo cp Build/obj/RELEASE_PPC/mach_kernel / Restart and if all is well you should have a new kernel running. Good luck finding the kernel you want, though. 10.2.3 hadn't been merged the last time I checked. mjk _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
