X1

Thinkpad X1 Carbon

These are the instructions for the 2016 X1 Carbon 4th Gen with i7-6600U + vPro

  • setup windows (a cmd window appears for a brief second?)
  • resize partition ("Disk management") -- reclaim up to 384 GB of space (393216 KB)

  • setup BIOS

    • Supervisor password (can not contain any special characters, which is suspicious, but 0-9 are ok)
    • Discrete TPM
    • Enable Virtualization and VT-d
    • Bottom Cover Tamper Detection - Enabled (YES!)
    • Computrace - Disabled
    • SGX - Enabled
    • Secure Boot - Enabled (this will break windows7; UEFI mode is not supported?)
    • Leave legacy boot option if you want to use windows

  • Linux install

    • To get to the boot device selection, hit F12 when the Lenovo screen is displayed
    • Something is wrong in the video setup? Black screen with a flashing cursor in the upper left corner.
    • Reboot, select "Option optoins" (Fn-F6) and select all of acpi=off
    • This will not find the WiFi card
    • "Instal Ubuntu alongside Windows 7" doesn't let you encrypt.
    • Encrypt home directory instead
    • System won't reboot since noacpi was set.
    • And reboot doesn't find the grub menu

next try... turn on secure boot, force efi and reinstall edit command line to add 'acpi=off' to the boot list

notes:

  • realtek 525a is a PCIe card reader (the MicroSD)
  • Validity Sensors is the fingerprint scanner
  • Skylake Gaussian Mixture Model?
  • 4.6 has Intel wifi drivers and fixes power management: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-rc4-wily/
  • run apt-get update after wards
  • iwlwifi power save isn't enabled, causing very high power draw (3W?). Add this to /etc/modprobe.d/iwlwifi.conf:
options iwlwifi power_save=Y

other packages to install: sudo apt-get install git openssh-server gnupg2 vim powertop gnome-tweak-tool

Flashrom

That is the older motherboard model; haven't taken a new photo yet.

sudo apt-get install subversion libpci-dev libusb-dev
make CONFIG_ENABLE_LIBUSB1_PROGRAMMERS=no

Doesn't work:

sudo ./flashrom -v --programmer internal
flashrom v0.9.9-r1954 on Linux 4.6.0-040600rc4-generic (x86_64)
flashrom is free software, get the source code at https://flashrom.org

Error: Extra parameter found.
Please run "flashrom --help" for usage info.

Calibrating delay loop... OK.

Coreboot

sudo apt-get install libncurses-dev golang pciutils dmidecode acpidump
git clone http://review.coreboot.org/coreboot.git
cd coreboot
make # take a break while stuff checks out kill it when it gets to "General setup"

Build the autotool:

cd utils/autoport
make -C ../ectool
make -C ../inteltool
go build

At this point autoport can try to build a source tree for this machine:

sudo ./autoport --input_log=logs --make_logs --coreboot_dir=../..

But the ACPI tables are known to be screwy and appear to make the script crash. Commenting out stuff that deals with the Southbridge allows it to finish, although things are pretty messed up (and there are no PCI devices available, etc).
