I have included the port-amiga list in this reply as I thought that the
amiga list was going away. No?

By coincidence, I am in a similar situation and have a few questions of
my own. I'll tell you what I have found out thus far. Anyone, please
feel free to correct me if I'm wrong or fill in the blanks as necessary.
1.) The A3640 will NOT work with V36 boot ROMs
(i.e. softkicked). You need 2.04 or 3.x ROMs.
2.) If you have V2.04 ROMs you need to have either:
a.) Page mode RAM in (at least) Bank 0, OR
b.) Upgraded Ramsey (to Rev. 7) and DMAC (to Rev. 4).
I am told that these chips are difficult to obtain
but I had no problem finding either. Note that if you
choose to upgrade the custom chips you MUST upgrade BOTH
of these chips for this to work.
3.) If you have 3.1 ROMs then no custom chip upgrades should be
necessary and static column RAM should work fine.
Now for my question. I am about to install the A3640 in my A3000
w/2.04 ROMs and WB2.1. As I understand it, in addition to the hardware,
a certain 68040.library is also necessary. I have searched high and low
but have not been able to locate such a library. This box spends most
(99%+) of its time running NetBSD so if not having this library simply
means a performance hit on the AmigaOS side then that's fine. If, on the
other hand, it means I cannot run AmigaOS (and thus cannot boot NetBSD)
then where do I get this library?
Also, could someone please verify the assertions in item 2 above. I
believe this to be correct but have heard unconfirmed info stating that
static column RAM would not work with 2.04 ROM even with the chip upgrades.
Many thanks in advance,
