-====== Information ======
-  * Lenovo T500 laptop
-====== Resources ======
-  * [[https://support.lenovo.com/solutions/pd001301|Specifications]]
-  * [[https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/43y6630_03.pdf|Hardware Maintenance Manual]] (([[https://thinkpads.com/support/hmm/hmm_pdf/43y6630_04.pdf|Mirror]]))
-====== Coreboot ======
-===== Issues =====
-  * When booting Ubuntu 18.10, there's a gfx error initially; type ''help'' and press ''Enter'' to boot
-  * :!: Be absolute certain to update the BIOS and ECP from the Lenovo Vendor BIOS with an attached rear-battery, as there is no way as of 2019/01/25 to update the ECP from Coreboot
-===== RAM =====
-==== Incompatible ====
-  * [[https://www.ebay.com/itm/8GB-DDR3-1066-MHZ-PC3-8500-2X4GB-SODIMM-MEMORY-FOR-MACBOOK-PRO-IMAC-MAC-MINI/330907626941|Generic 1066MHz RAM with UPC 609713501042]] ((incompatible with Coreboot 2018/12 (unknown day), incompatible with Libreboot 20160907, untested with Lenovo Vendor BIOS 3.26))
-==== Compatible ====
-  * [[https://www.gskill.com/en/product/f3-8500cl7d-8gbsq|G.SKILL F3-8500CL7D-8GBSQ]] ((compatible with Coreboot 2019/01/25, untested with Libreboot, untested with Lenovo Vendor BIOS 3.26))
-===== Dependencies =====
-==== Fedora Workstation ====
-  * :!: Fedora Workstation 29 **cannot** be used to compile older versions of Coreboot wanting a non-matching major GCC version for crossgcc ((see [[notes:old_coreboot|Old Coreboot]] notes))
-  sudo dnf install make ncurses-devel acpica-tools flex bison gcc-c++ patch zlib-devel gcc-gnat pciutils-devel
-==== openSUSE Tumbleweed ====
-****
-  sudo zypper install git-core make cmake ncurses-devel acpica flex bison gcc-c++ patch zlib-devel gcc-ada pciutils-devel
-===== Download Source =====
-==== Coreboot ====
-****
-  cd ~ && mkdir -p ~/'Projects' && rm -Rf ~/'Projects/coreboot/src' && git clone --branch 'master' --depth '1' --recurse-submodules 'https://review.coreboot.org/coreboot.git' ~/'Projects/coreboot/src' && sync
-==== Libreboot ====
-  * This is necessary for [[#ich9gen|ich9gen]]
-  cd ~ && mkdir -p ~/'Projects' && rm -Rf ~/'Projects/libreboot/src' && git clone --branch 'master' --depth '1' --recurse-submodules 'https://notabug.org/libreboot/libreboot.git' ~/'Projects/libreboot/src' && sync
-===== ich9gen =====
-==== Notes ====
-  * https://libreboot.org/docs/hardware/gm45_remove_me.html
-  * Generates a descriptor image free of IME ((Intel Management Engine)), and allows for use of the on-board ethernet controller
-==== Compile ====
-****
-  cd ~/'Projects/libreboot/src/resources/utilities/ich9deblob' && make clean && make jobs='16' && sync
-==== Generate ====
-  * :!: Change ''x'' to the on-board Ethernet MAC address formatted as ''XX:XX:XX:XX:XX:XX'' ((this should look like --macaddress ''XX:XX:XX:XX:XX:XX''))
-  cd ~/'Projects/libreboot/src/resources/utilities/ich9deblob' && ~/'Projects/libreboot/src/resources/utilities/ich9deblob/ich9gen' --macaddress 'x'
-==== Move ====
-  * This copies the generated ''ich9fdgbe_4m.bin'' to the necessary folder for Coreboot
-  * The T500 uses the same board build as the T400 in Coreboot currently, hence the ''t400'' mainboard name
-  * :!: If the BIOS chip is a different size other than ''4096KB'', change this
-  mkdir -p ~/'Projects/coreboot/src/3rdparty/blobs/mainboard/lenovo/t400' && mv ~/'Projects/libreboot/src/resources/utilities/ich9deblob/ich9fdgbe_4m.bin' ~/'Projects/coreboot/src/3rdparty/blobs/mainboard/lenovo/t400/descriptor.bin' && ls ~/'Projects/coreboot/src/3rdparty/blobs/mainboard/lenovo/t400/descriptor.bin' && cd ~ && rm -Rf ~/'Projects/libreboot' && sync

-  * :!: The initial flash **must** be done by an external programmer ((Running the Lenovo vendor BIOS through ''ifdtool'' with the ''--unlock'' flag does **not** unlock the chip; **so any re-flash to the Lenovo vendor BIOS will require an external programmer to flash different firmware**))
