I have only used Dreamup twice but I think when you flash with the null modem cable there is a box you need to tick to do 'Flash erase'.
Hmm, I'm not seeing any flash erase option. I did manage to get some more info from the Linux boot load sequence (by press space bar then entering console=ttyS0,115200 <ENTER> when I saw Linux/PPC load via Hyperterminal). I'm just wondering if there is any other tool I can use to flash the 600 via null modem (other than DreamUp)
