OK...
Now I seem to have conflicting answers here...
One of you says that they are only physically different, but have the same data... And another says they are physically the same, but different data... LOL
I am actually a bit confused as to why the A2000/500s have 1 and the 3000/4000s have 2. Is one for the onboard HD controller and one for the System?
If so, do they each have the same ROM image and only use the portion that they need?
I'm just wondering if I can make an image of my A3000s 3.1 roms and just do a software re-kick with that rom on my 4000.
