Suggestions and notes about the page format and style

  • The info displayed by the UART commands: "hversion", "revision", and "version" is not needed in this page because the thermal config area of the syscon EEPROM is not directly dependant of them (some motherboards shares the same thermal config, but have different identifyers). The 2nd line of the "eepcsum" for mullions is not needed either because it can be seen in the hex dump of the thermal config itself (last 2 bytes of it), and the "eepcsum" for sherwoods doesnt seems to be useful because includes other areas of the EEPROM that could be unique per-console, but this is not clear yet, are needed more samples. All this identifyers are kept in the page because there are many things that are still under research and eventually could help us to understand it better, but most probably in long term is going to be better to delete them, move them to other wiki pages, or to think in a different way to display that kind of info
  • By now the page sections with the thermal configs are named by his checksums as a prevention to dont make any assumptions, eventually could be labeled "by syscon model", "by motherboard model", or even "by PS3 model", but is not clear if this kind of simplification could make us fall in some mistakes, as example, we have 2 thermal configs for DIA-001 and the only thing we can do by now to simplify his names could be something like "thermal config for DIA-001 14 speeds" and "thermal config for DIA-002 16 speeds", but thats not good enought because eventually someone could find another official one for DIA-001. The collection is still incomplete so is a bit soon to decide how to label them, in the meantime we need to deal with that weird names, are an annoyance but are intended to be a failproof way to identify them
  • The "eepcsum" command in mullion displays 5 lines, the first line is common for all motherboards of a specific model, the second line is the thermal config, the third line is common for all motherboards of a specific model but to access syscon internal mode (and unlock all commands) is needed to write a byte in it and this changes the checksum of this area... so we are going to see samples where the third line of the "eepcsum" command differs just because the syscon was "unlocked" (in other words, his EEPROM was modifyed)
