Thanks for the help when I had kickstart/booting problems. It was solved by using better cooling on the CPU which then worked fine as you know.
I must admit to being flummoxed too why your CPU did not work in your A1 ?
Your CPU worked first time as soon as I plugged it into my mobo. As both worked here I expected that my 7451 probably wouldn't help you either. However, I am really glad though that for some inexplicable reason it does work and your A1 is up an running OS4.1 now
I am delighted with the 7457 which runs fine on my A1 - go figure. The extra speed makes everything a bit nippier especially IBrowse and of course GCC when compiling DU :o)
