This is based on the code from the 8470p port. Tested on the quad core/quad SODIMM version. This laptop uses discrete MXM 3.0b graphics cards. Tested working with both Quadro K3000M and GTX 980M 8GB. The laptop must be completely disassembled down to the motherboard to perform the initial flash, subsequent flashes can be done internally via flashrom. There is a simple mod that can be performed to make subsequent external flashes easier in case of a brick, I'll put more information on this on the wiki later. The lack of an MXM structure built in to the firmware causes the GPU to enter a mode with nerfed performance, there is a workaround though, I'll add this to the wiki as well. I have no info on EHCI debugging. Tested and working: - memory: 4G+4G, 4G+4G+4G+4G - Linux (Debian Stretch with kernel 4.9.0) booted from SeaBIOS payload with graphics init disabled in coreboot. I allowed SeaBIOS to load the VBIOS from the MXM. - WLAN - keyboard, trackpoint and touchpad - USB - serial port on dock - fan control - VGA - DisplayPort - Audio - Both HDD SATA ports, ODD SATA, eSATA - S3 with SeaBIOS 1.11, SERCON must be disabled - Brightness and volume FN keys - Mute and calculator hotkeys - Status LEDs - Bluetooth Not working: - GRUB2 as payload will freeze. Has something to do with at_keyboard module. The built in keyboard requires this module to function though. - Sleep FN key - WiFi toggle and internet browser hotkeys - S3 fails to resume (restarts) if the laptop is removed from AC power, or gets unplugged and then plugged back in while suspended. Sleep status LEDs remain normal during this process.

------------------------------------------------------------------------------- coreboot README ------------------------------------------------------------------------------- coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload. With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required. coreboot was formerly known as LinuxBIOS. Payloads -------- After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot. See https://www.coreboot.org/Payloads for a list of supported payloads. Supported Hardware ------------------ coreboot supports a wide range of chipsets, devices, and mainboards. For details please consult: * https://www.coreboot.org/Supported_Motherboards * https://www.coreboot.org/Supported_Chipsets_and_Devices Build Requirements ------------------ * make * gcc / g++ Because Linux distribution compilers tend to use lots of patches. coreboot does lots of "unusual" things in its build system, some of which break due to those patches, sometimes by gcc aborting, sometimes - and that's worse - by generating broken object code. Two options: use our toolchain (eg. make crosstools-i386) or enable the ANY_TOOLCHAIN Kconfig option if you're feeling lucky (no support in this case). * iasl (for targets with ACPI support) * pkg-config * libssl-dev (openssl) Optional: * doxygen (for generating/viewing documentation) * gdb (for better debugging facilities on some targets) * ncurses (for 'make menuconfig' and 'make nconfig') * flex and bison (for regenerating parsers) Building coreboot ----------------- Please consult https://www.coreboot.org/Build_HOWTO for details. Testing coreboot Without Modifying Your Hardware ------------------------------------------------ If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU. Please see https://www.coreboot.org/QEMU for details. Website and Mailing List ------------------------ Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website: https://www.coreboot.org You can contact us directly on the coreboot mailing list: https://www.coreboot.org/Mailinglist Copyright and License --------------------- The copyright on coreboot is owned by quite a large number of individual developers and companies.
