How far have you got with this system anyway? (I've seen your other 060 reads 040 thread!)
Have you got the upgraded hardware drivers running from the Kickflash? (the one's that can anyway). Is the 4000D clean and white? What Zorro cards are you using? Is there anything on this system that you are missing/have extra when comparing to your old 1200 system?
Also more on-topic, does the Kickflash enable you to do everything that your custom Kickstarts did in your 1200? (i.e. go straight into the OS on cold boot?)
