Readme for Seta1 v1.00fr, 02/04/2005 ================================== Documentation and program copyright Gary Colville, 2005. 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.
