What Is SetA1?
--------------
It's a utility that can tweak the various parts of the
AmigaOne hardware to do interesting things. Please note
that this is unfinished software. Use with care.


How Do I Use It?
----------------

Just run SetA1 from the CLI. Arguments are explained below:


RAMINFO  -- Prints information on the memory in your A1. The
            timings listed here are those currenty in use, not
            the 'recommended' settings that are stored on the
            SPD.

BENCHMARK-- Runs some quick memory benchmarks.

SLOWMEM  -- Automatically applies a pre-set that should slow the
            memory down and increase stability. This option is
            independent of the rest and can be used in conjunction
            with them - ie, if SLOWMEM on its own doesn't work for
            you try using RAS2CAS=3 R2A=7 SLOWMEM.

FASTMEM  -- Shaves memory timings to gain extra speed. As with
            SLOWMEM this option is independent. For example, if
            you have really amazing memory you could run SetA1 with
            the parameters RAS2CAS=2 R2A=2 CL=2 FASTMEM.

FASTCAS  -- Yet another speed-up option. This option may change some
            of the specific memory timings.

THROTTLE -- Reduces CPU throughput to prevent overheating. Throttle
            levels from 0 to 8 are available, with 0 being full speed
            and 8 being very low performance.

ICACHE   -- Enables CPU instruction cache.

NOICACHE -- Switches off the CPU intruction cache.

R2C      -- Sets the delay when switching from RAS (row address
            strobe) to CAS (column address strobe) signals.
            Must be between 1 and 3 clocks.

R2A      -- The delay when moving from memory refresh to active
            state. Must be between 1 and 7 clocks.

CL       -- Sets the CAS Latency (PC users will be familiar with
            this setting). Must be either 2 or 3 clocks.


Future Development
------------------

This is the final version of SetA1. I have sold my AmigaOne and all
work on the code has stopped as of this release.
