RomCache040+ 1.1 ©SpeedGeek 2017 (MMU Handler ©Michael Sinz 2001)

INTRODUCTION:
RomCache040+ is a tool to enable the Extended ROM cache for
68040 and 68060 users. "Extended" ROM areas are used to
make 1MB or larger Kickstart ROMs. These areas default to
"NoCache" in the MMU tables of most 68040/060 libraries.

FEATURES:
- Enables "Extended" ROM cache for the following areas:
1) $A80000*
2) $E00000 512KB
3) $1000000*
- Smaller and faster than the Enforcer MMU tool
- Safer than the Enforcer MMU tool because:
1) It has working 68040/060 library detection code (hint)
2) It has ROM Header detection code
3) It only modifies the CM descriptor bits of the MMU table
- 100% Assembler code
* MMU table setup may determine address range and size

REQUIREMENTS:
- Amiga with 68040 or 68060 CPU and MMU
- 68040.library or 68060.library
- 1MB or larger Kickstart ROM(s) installed

WARNINGS:
Do NOT use RomCache040+ if the 68040 or 68060 library developer
has already provided you with the tools to do the job (e.g.
THOR's MMU.library). The MMU Handler developer says this code is
a "Hack". This tool uses an optimised variant of this hack and
makes certain assumptions about the MMU table setup which could
cause it to fail (e.g. speed has it's price).
