Ahhh...now, you see? This is a thread worth sinking my teeth into. I too have been considering the 4G+ upgrade on my OS3.1 A3K, but wanted to avoid all that PFS bloat (besides my System partition is filled to the max-all 38 Megs of it!!).
The newer OS's seemed not to get it all together, passing off boing bags to fix bugs and incompatabilities, so I never upgraded my 3.1 'officially'. I'm glad to learn of the "ffstd64.lha" file on Aminet, and I'm going to at least download the archive for the future.
This whole thread has been very informative to me,guys. Thanks to all of you!! BTW-Happy New Year (yeah, it's been a while since my last visit here).
Cheers,
