Per the history in the BIOS bundle... 104 - MCU update for side-band analysis bug; - Windows Power Button issue Solved - ACPI: I2C new test devices and HSUART virtual COMs; - ASPM flag in FADT to make OS trust BIOS settings; - Thermal Zones corrected for fake values causing performance degradation; - PM register preserving across S3 to avoid events disabled (PWBTN issue); - some setup items aesthetical adjustments; - Embedded Controller Firmware Optimazed Programming - FW 0B with: * Corrections in CEC management and alignment to latest framework * WDT time-out correction; * IRDA mask corrected.
I noticed it looks like the FW changed to 0C as opposed to 0B as mentioned in the change-log, anyone else notice? Bootloader went up to 0B02 as well and now shows the latest intel microcode for this chip as 410.
