Cool!  When OS3.1 is installed (or 3.9 or whatever) it should create a brand new startup-sequence and overwrite the one you just made.  As a rule, I always add the CPU line to any machine I have worked on - and test it for a while to see how it works.  Some machines don't like the "burst" command due to other hardware they may have installed.

Regardless, have fun!

There's no way an A3k could have 6 MB (fast) onboard. You can use 1-4 banks of memory with either 1 MB (4x256Kb chips) or 4 MB (4x1024Kb chips) each - no mixing possible - you could have 1, 2, 3, 4, 8, 12 or 16 Meg fast RAM, but not 6 (FastROM uses 512 KB of RAM, but certainly not 2 Megs).

Showconfig tells you where the RAM is at. Chip is $2000-$1FFFFF, Fast grows from $7FFFFFF downwards (to $7400000 if you've got 12 Megs). :-)

@all
Anyone with spare 4 MB static column to sell? Or trade for 4 MB fast page?
