Dear Ben, I have tried, many BIOS versions compatible with including Embeded Controller 3.03 (e.g. 3.05a mentioned by you) but during downgrading for BIOS below 3.12 I always get: "CPU ID is not correct for this system."
Lenovo support does not recognize their hardware. type: 2374-g1g does not exists for them. So it seems I sucked with this issue. Thank you for your attention. Please close the issue, I will use patched speedstep-centrino for myself only. rgds rumi
