FMSM i got it back .....after reformatting my card in the cam to start from scratch, i downloaded a fresh CHDK . I then extracted that. I then downloaded another and pulled the psi2 file out seperate. I then cut that and pasted it in card "G" away from other folders. And it has worked.
I also did change 00001E0 to BOOTDISK although you said thats not really needed. I wont celebrate too much so as not to jinx it. I dont want to trip on that part of the learning curve again.
Thanks waterwings
