I'm having an issue installing a copy of 10.4 server on my 1.8Ghz iMac. It goes along and installs fine from the 1st disc, i then put in the second and it installs all the software on there, but then hangs when it reaches the 'optimizing system performance' bit.

I then have to force shut down and when it boots back up it goes through the process of installing the software from disc 2 and hangs at the same point.

Is there any way that i can force the os to think that the 2nd cd was installed, so it will boot normally?
