News Summary

  • The ThinkPad x61 has a GM965 northbridge and an ICH8 southbridge.
  • There are no leaked docs out there on this platform so reverse engineering would be the only way.
  • In March I was experimenting with using LLM technology more in my workflow.
  • It turns out they are a great tool at speeding up the process.
  • Normally reverse engineering requires quite some dedication.
  • 3-6 months for porting this whole platform (gm965/ich8 for x61) is not out of the question.
  • That's time I for sure don't have for this purpose.
So after a few days the code seemed to work quite fine with multiple DIMMs in different combinations. Time to upstream! Doing native raminit on x86 (in coreboot) is quite a lost art.
