We were having some issues with our server earlier today. It should be all better now.
cheers
/Tim - Hi,
How are you doing ?
I was following the steps listed here:

I am running my L138 CPU at 372 MHz, which results in the EMIFA bus running at 93MHz instead of 100 MHZ.

Are you using CS4 or CS5?
0x66000000 corresponds to CS5.
