Kickstart RAM mirror
« on: October 30, 2010, 08:52:05 PM »
Having recently come into possession of an A2630 accelerator, I was looking for information on any performance tweaks to get the most out of it. While looking through the Wikipedia article on Kickstart, I noticed that, as I'd guessed, it's possible to set an Amiga with an MMU (such as an 030-based system) to map an area of RAM in place of the ROM. Since the 2630 has 32-bit fast RAM on-board and Kickstart contains a lot of heavily-used code, I'm guessing this would provide a pretty fair performance boost. However, there doesn't seem to be any software for doing this provided with the board, at least not that amiga.resource.cx has. Is there a third-party utility that can do this, or would I have to hack one up after [strike]skimming[/strike] exhaustively reviewing the MMU documentation?

Uh, no. Is that an AmigaDOS utility I don't know about?

Edit: Yes, yes it is. The more you know...
