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 in all cases (some motherboards shares the same thermal config, but have different identifyers). The 2nd line of the "eepcsum" for sherwoods is only needed either because it can be seen in the thermal config itself, and tghe "eepcsum" for sherwoods doesnt seems to be useful because includes other areas of the EEPROM that could differ "by PS3 unit", but this is not clear yet, are needed more samples. In general... 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 are named by his checksums as a prevention to dont make any assumptions, eventually could be labeled "by PS3 model", or "by motherboard model", or even "by syscon model", but is not clear if this kind of simplification could make us fail in some mistakes... just 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 old" and "thermal config for DIA-002 new", 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 and in the meantime we need to deal with that weird names, are an annoyance but are intended to be a failproof to identify them
Unknown bytes
There are only 4 unknown fields in the thermal configs, feel free to discuss them here
unknown0
- A value with 1 byte lenght
- Mullions: always 0x00. Located at relative offset 0x182
- Sherwoods: always 0x00. Located at relative offset 0x152
unknown2
- A value with 1 byte lenght
- Mullions: always 0xFF. Located at relative offset 0x18F
- Sherwoods: always 0x00. Located at relative offset 0x153
Note: it seems the position of the unknown2 was displaced 0xD bytes to the left in sherwoods... causing a displacement to right of 0x1 byte to the other values in between them (initial_fan_duty, initial_fan_time, and the unknown1)
Unknown1
Values found in the official thermal configs:
Mullions FF FF FF FF FF FF FF FF FF FF (COK-001 PROTO) FF FF FF FF FF FF FF 00 FF 00 (COK-001, COK-002, SEM-0001) FF FF FF FF FF FF 8B 00 FF 00 (COK-001 REFURB) FF FF FF FF FF 81 FF 00 FF 00 (DIA-001) FF FF FF FF FF 81 FF 00 00 00 (DIA-001, DIA-002, DEB-001)
Sherwoods FF FF FF FF FF 81 88 81 88 FF (VER-001) FF FF FF FF FF 84 88 84 88 FF (DYN-001) FF FF FF FF FF 84 8B 84 8B FF (SUR-001, JTP-001, KTE-001, MSX-001, MPX-001) FF FF FF FF FF 84 8B 84 8E FF (NPX-001) FF FF FF FF FF 7A 89 84 8E FF (PQX-001, REX-001)
The thermal configs found in NPX-001 and PQX-001 motherboards only differs in a couple of bytes located at the "unknown1" field
