cannot execute binary fileI also tried flasher.linux_ppc and got the same error message that's already been reported with Mac OS X's flasher:
Invalid FIASCO subblock count(2)So as soon as I have access to a WindowsXP box, I'm going to try the Ubuntu LiveCD on that. I'm at least optimistic now (last night I was seriously considering putting the 770 on Ebay and washing my hands of it).
