[quote]Convert your Update CD to a full Install CD In the meantime, we found a work-around that may be even better than the one we were looking for. Instead of finding a file on the hard drive that we could modify to fool the Installer, we found a file on the Installer that we could delete and thereby bypass the checking process altogether!
We found the file by comparing a Mac OS X 10.1 "full" Install CD with an Update CD. Both CDs had the aforementioned VolumeCheck file. However, only the Update CD had the CheckforOSX file. Could this be the only critical difference between the two CDs? What if we made a bootable copy of the OS X Update CD, but with the CheckforOSX file missing? Would it act as a full install CD? We tried it. It worked! In brief, here is what to do:
Using instructions posted on this page, create a disk image of the Update CD.
Delete the CheckforOSX file from the Essentials.pkg file in System/Installation/Packages folder of the image file. [You need to use the Open Package Contents contextual menu item to access this file.]
Burn the image to a CD using Disk Copy.
You can now boot from this CD. When you do, it will list any volume - even one that has no version of Mac OS X at all - as eligible for an install of Mac OS X 10.1. We did not test to see if this actually correctly installed the OS, but we have no reason to believe it would not. This method thus apparently converts an Update CD into a full install CD! A neat trick (although we suspect Apple may not find this so wonderful). <hr></blockquote>
