Late 2026 - I forked this from another user who ALSO forked it from StarLabs, since they have removed all the old AMI BIOS ROMs for Labtop etc. Useful when their buggy Coreboot bricks your machine and you want to flash it back!
Version history below is shared across all supported coreboot boards in this repository, starting from when release notes became unified across boards.
General Updates: * Improved sleep/wake and reset reliability * Added support for EFI capsules for easier, more secure updates * Updated BIOS setup layout, with a simpler user interface and clearer security shortcuts New Options: * [StarFighter] Memory Speed Security Updates: * Add an option to lock the BIOS Setup with a password * BIOS Lock is now enabled by default * Added TCG OPAL Storage disk encryption support, including S3 unlock support * Improved Secure Boot key enrollment behavior when a KEK is already present Bug Fixes / Enhancements: * Fixed power LED “breathing” behavior in S3 * Fixed Wake-on-LAN on Byte (including Wake-on-LAN in S5 where supported) * [StarFighter] Enabled the card reader
General Updates: * Improved sleep/wake and reset reliability * Added support for EFI capsules for easier, more secure updates * Updated BIOS setup lauouy, with simpler user-interface New Options: * [StarFighter] Memory Speed Security Updates: * Add an option to lock the BIOS Setup with a password * BIOS Lock is now enabled by default Bug Fixes / Enhancements: * Fixed power LED “breathing” behavior in sleep (S3). * Fixed Wake-on-LAN on Byte * Updated platform defaults based on fan presence
General Updates * EC startup time has been reduced from 415ms to 170ms * Hardened power sequence to avoid getting stuck * Updated Intel microcode * eSPI Virtual Wires are now interrupt-driven for better response times * Updated default settings aimed at performance * Remove the power button debounce (double press is no longer required) * Updated firmware menu that now shows battery level and allows adjusting the time and date * The system will now wake if suspended, and the battery gets too low New Options: * Enable/Disable/Dim the power LED * Enable/Disable/Dim the charging LED * Enable/Disable Total Memory Encryption * Enable/Disable BIOS Lock Security Updates: * Updated UEFI revocation list * Added support for LUKS and BitLocker Bug Fixes / Enhancements * Fixed reset paths in coreboot to avoid the system hanging when changing settings that required global resets * Guard against SMBUS transactions not completing * Increase SMM store size in coreboot to allow UEFI revocation list updates to be installed from the LVFS * Fixed backlight level restoration after suspend (S3) * Fixed resuming from hibernation (S4) * Fixed an issue that prevented powering off in certain conditions * Fixed sound output on Windows * Fixed an issue where the fan could stall * Fixed disabling the card reader * Fixed Device Manager constantly refreshing on Windows * Fixed the capabilities reported by the TPM driver
General Updates: * Added capsule update support, with graphical update progress, more reliable flashing, and better preservation of existing settings and unchanged firmware data * Reworked the firmware setup menu into a cleaner Settings-style layout, with clearer Boot and Security sections New Options: * Configurable boot timeout * Digital Signal Processor * [StarFighter] Touchpad Vibration Intensity * [StarFighter] Touchpad Click Force * [StarFighter] Touchpad Release Force * [StarFighter] Touchpad Tracking Speed * [StarFighter] Speaker Idle Security Updates: * Added BIOS password protection * Added TCG OPAL storage support for compatible NVMe drives, including S3 unlock support Bug Fixes / Enhancements: * Added better HiDPI scaling in firmware setup and improved graphics handoff, helping hibernation (S4) behave more reliably * Corrected panel timing values against panel datasheets across current Star Labs platforms * Increased PWM frequencies across supported boards to reduce flicker * Added staged NVMe power sequencing on supported platforms so third-party and slower-to-initialize drives initialise more reliably * [StarFighter] Enabled the card reader in firmware * [StarLite Mk V / Horizon] Increased speaker output configuration to the intended 2.5W path * Improved keyboard scan debounce handling so new key presses are detected more consistently * Improved S3 power LED breathing behaviour for smoother and more consistent transitions * Simplified reduced-brightness handling for the LEDs * [Byte Mk III] Fix fan curve setting
General Updates: * Added support for AMD Cezanne models (Byte Mk I and StarBook Mk VI) * Added coreboot support for Byte Mk I and StarBook Mk VI-AMD New Options: * Custom power profile controls for PL1, PL2, PL4, and CPU thermal throttle temperature * Per-port PCIe power management controls * HDA DSP firmware setup toggle Bug Fixes / Enhancements: * Reduced false CPU throttling from charge-controller PROCHOT while preserving brown-out protection * [StarFighter] Reduced touchpad startup delay and fixed touchpad settings not being applied * [StarFighter] Improved Wi-Fi, Bluetooth, and touchpad setup handling * [StarLite Mk V] Improved battery free operation
General Updates: * Added support for AMD Cezanne models (Byte Mk I and StarBook Mk VI) Bug Fixes / Enhancements: * Improved capsule update reliability * Fixed hibernation failures caused by inconsistent payload memory maps * Ignored malformed OS-created UEFI variable records instead of blocking boot * Avoided EDK2 serial port reinitialisation * Dropped shell networking when networking support is disabled * Disable TPM1 * Fixed PCR0 Reconstruction * Improved HiDPI logo, console text, and graphics handoff handling * Reduced false CPU throttling from charge-controller PROCHOT while preserving brown-out protection * Improved low battery handling with a warning splash, adjusted wake threshold, and graceful critical battery shutdown * Dynamically set PL4 from charger and battery state * Fixed memory speed changes reusing stale training data * Fixed ANX7447 dead battery charging * Added Fn+F hot key for 100 0.000000an duty * Stored the serial number in firmware variables * [StarFighter] Reduced touchpad startup delay and fixed touchpad settings not being applied * [StarLite Mk V] Improved battery free operation and fixed auto-rotation on Ubuntu * [StarBook MkVIr2-Intel] Fixed blue sleep LED breathing * Improved keyboard scan debounce to reduce ghosting and missed keys
