I have a brand new system sitting there that I can't use. Together with a nice 23 inch display. I am reasonably sure that if I can lower the clock the problem will go away.

I was trying to do it using darwinbuild, which makes the whole build-process simple. But the latest plist I see is for 10.4.5, not 10.4.6. Yep, did it yesterday, just follow http://developer.apple.com/documentation/Darwin/Conceptual/ KernelProgramming/build/chapter_18_section_3.html It's pretty much accurate, except that you may have to copy some headers into appropriate places by hand to build kextsymboltool.

There doesn't seem to be the necessary plist file 8I127.plist for this version, or at least I was unable to find it. Has anyone else built it? Note - this is for the PPC version, not for Intel.

Or, just delete it and then close it. (Requires using Unix file APIs, of course. You can't delete an open file using File Manager.) When you're initializing a large file, I recommend you incrementally initialize the file with progress UI. You can do this by setting the file size and then writing zeros, say, 1MB at a time. Another method I've seen is to incrementally resize the file; you increase the file size by 1MB, then close it, then open it again and increase it another 1MB, and so on. This may be more efficient because the OS handles writing the zeros for you, but I haven't timed it--it could be slower to open and close the file repeatedly. It sure would be nice if the OS could do this asynchronously. Instead of making the process closing the file wait on the initialization, make opens wait--or better yet, stop writing zeros to the file and treat it as though it had just been opened and resized.
