idone, detailing the PS3 BiOS chip being pulled and starting to be traced as follows:
For some time, we have been talking about the PlayStation 3 BiOS, and up to date there is no public info about the IC which does this job and the way it stores the information.
Here is a quick briefing of what we have done so far (pictures in sequence with the below text, spread across the three images below):
Pic #1: The reference of this IC is CXR713120-202GB.
Pics #2 & #3: Thanks to
KnightSolidus we have these photos with the ways of this IC and some notes of connections references with colors.
Pic #4: The PLAYSTATION 3 BIOS is also known as SYSTEM CONTROLLER (SysCon)
Pic #5: As we can see in the image, SYSTEM CONTROLLER uses an SPI interface to communicate with the CELL eeprom, on which possibly it will know how to behave. We think it *might* be something interesting to work with.
Pic #6: Using this SPI interface, we can try to cause a livelock that would get us the checkstop.
Pic #7: Here we can see the CXR SYSTEM CONTROLLER, internal diagram. We believe that the UART port...
