Dev install infinite loop


I tried to install the dev CD. the first two times I had sleep mode on, and after 3 hours of waiting and coming back to the computer to find it had a black screen, I restarted. (One bug already, sleep mode should not activate in the middle of an install!)

Anyhow, after the second attempt, I disabled sleep and installed. I went to sleep, and 7 hours later I woke up to find it had just been stuck at the same point it was at the first two times!

Obviously, it had somehow got into an infinite loop.

How do I tell Apple about this?

I have an iMac 350mhz, 128mb RAM, 64MB of which is non Apple RAM. (It is recognised fine because I didn't do a firmware update)
