+Introduction
+============
+
+ROM images for Dell Latitude E6430 are available for flashing in the Libreboot
+releases *after* 20230625, or you can compile a ROM image for installation via
+lbmk, see: [build instructions](../build/)
+
+Only the Intel GPU variants are supported, currently. All models with Intel GPU
+are assumed to work.
+
+Unlike the E6400, this one does require a neutered Intel ME image to run. This
+means running it through `me_cleaner` before flashing; the Libreboot build
+system does this automatically, during build, or you can insert a neutered
+ROM image using the vendor scripts, see guide:
+
+[Insert vendor files](../install/ivy_has_common.md)
+
+As with the E6400, this one is flashable in software, from Dell UEFI firmware
+to Libreboot. Please refer to the installation instructions.
+
+**To install Libreboot, see: [E6430 installation
+instructions](../install/e6430.md)**

+title: Flashing the Dell Latitude E6430
+x-toc-enable: true
+...
+
+Introduction
+============
+
+This guide is for those who want libreboot on their Latitude E6430 while
+they still have the original Dell firmware present. This guide can also be
+followed (adapted) if you brick your E6430, and you want to recover it.
+
+**The Intel video initialisation is libre, implemented with publicly available
+source code via libgfxinit, from the coreboot project.**
+
+Only the intel GPU variants are supported. The Nvidia GPU variants are untested
+and should be assumed *broken* by default.
+
+Flash chip size {#flashchips}
+===============
+
+Use this to find out:
+
+ flashrom -p internal
+
+The internal flash size is 12MiB on this board; physically, an 8MiB and 4MiB
+chip (two chips) but this distinction only matters for external flashing.
+
+MAC address {#macaddress}
+===========
+
+The MAC address is part of the ROM image that you're flashing. You can change
+it at any time, before or after you've flashed Libreboot; you can also change
+it in the *Dell* BIOS, if you really want to. This is for the onboard gigabit
+ethernet device.
+
+Refer to [mac\_address.md](../hardware/mac_address.md).
+
+It is recommended that you run *nvmutil*. See:
+
+[nvmutil usage manual](nvmutil.md)
+
+The `nvmutil` software is specifically designed for changing MAC addresses,
+and it implements a few more safeguards (e.g. prevents multicast/all-zero
+MAC addresses) and features (MAC address randomisation, ability to correct or
+intententionally corrupt(disable) GbE sections if you wish, swap GbE parts,
+etc). - **it is also the only software available for this. Please do not
+use ich9gen on this board. This is an ivybridge board, not ICH9M.**
+
+Intel GPU: libre video initialisation available
+===============================================
+
+Libreboot uses coreboot's native `libgfxinit` on this platform, for
+variants with Intel graphics.
+
+Libreboot releases after 20230625 will support this board, otherwise you can
+refer to the [build instructions](../build/)
+
+Nvidia GPU: Video BIOS Option ROM required
+==========================================
+
+UNSUPPORTED. DO NOT BUY THE NVIDIA VARIANT.
+
+Only the Intel GPU variants are supported. It is believed that the Nvidia
+variants still have Intel GPUs in them, configured via hardware mux, but this
+has not yet been configured or tested in the coreboot code; you should assume
+that the Nvidia models do not work.
+
+How to flash internally (no diassembly)
+=======================================
+
+Warning for BSD users
+---------------------
+
+**NOTE (15 October 2023): The util is now called `dell-flash-unlock`, but it
+was previously called `e6400-flash-unlock`. Links have been updated.**
+
+BSD *boots* and works properly on these machines, but take note:
+
+Nicholas's [dell-flash-unlock](https://browse.libreboot.org/lbmk.git/plain/util/dell-flash-unlock/dell_flash_unlock.c)
+utility has been ported to OpenBSD, but *other* BSDs are assumed unsupported for
+now. The `flashrom` software is available on BSD systems. Libreboot's build
+system has *itself* not yet been ported to the BSDs, but you can use the
+flash unlock utility.
+
+NOTE: BSD is mentioned above, but the only BSD tested for `dell-flash-unlock`
+is OpenBSD, as of 15 October 2023.
+
+Flashing from Linux
+-------------------
+
+MAKE SURE you boot with this Linux kernel parameter: `iomem=relaxed` - this
+disables memory protections, permitting `/dev/mem` access needed by flashrom.
+The flash is memory mapped and flashrom accesses it via `/dev/mem`.
+
+You can flash Libreboot directly from the vendor (Dell) BIOS, without taking
+the machine apart. It can be done entirely from Linux. It will probably also
+work on BSD systems, but it has only been testing on Linux thus far.
+
+**NOTE (15 October 2023): The util is now called `dell-flash-unlock`, but it
+was previously called `e6400-flash-unlock`. Links have been updated.**
+
+Check `util/dell-flash-unlock` in the `lbmk.git` repository, or in release
+archives for Libreboot releases from 20230423 onwards.
+
+Go in there:
+
+ cd util/dell-flash-unlock
+ make
+
+With this program, you can unlock the flash in such a way where everything
+is writeable. Information about how to use it is in the `README.md` file which
+is included in that program's directory, or you can read it online here:
+
+<https://browse.libreboot.org/lbmk.git/plain/util/dell-flash-unlock/README.md>
+
+Literally just run that program, and do what it says. You run it once, and shut
+down, and when you do, the system brings itself back up automatically. Then
+you run it and flash it unlocked. Then you run it again. The source code is
+intuitive enough that you can easily get the gist of it; it's writing some EC
+commands and changing some chipset config bits. The EC on this machine is
+hooked up to the `GPIO33` signal, sometimes called `HDA_DOCK_EN`, which sets
+the flash descriptor override thus disabling any flash protection by the IFD.
+It also bypasses the SMM BIOS lock protection by disabling SMIs, and Dell's
+BIOS doesn't set any other type of protection either such as writing to
+Protected Range registers.
+
+When you flash it, you can use this command:
+
+ flashrom -p internal -w libreboot.rom
+
+Where `libreboot.rom` is your E6430 ROM. *Make sure* it's the right one.
+If flashrom complains about multiple flash chips detected, just pick one of
+them (doesn't matter which one), with the `-C` flag as directed; just pick one,
+and if it doesn't work, try the next.
+
+When you see flashrom say `VERIFIED` at the end, that means the flash was
+successful. If you don't see that, or you're unsure, please [contact the
+Libreboot project via IRC](../../contact.md).
+
+BACK UP THE FACTORY BIOS
+========================
+
+The `-w` option flashes `libreboot.rom`. You may consider *backing up* the
+original Dell BIOS first, using the -r option:
+
+ flashrom -p internal -r backup.rom
+
+AGAIN: make sure to use `-C` accordingly, if you need to pick a chip (where
+flashrom has detected multiple chip definitions). Just pick one, any of them
+will probably work, if not try the next.
+
+Do this while in a flashable state, after the 2nd run of `dell-flash-unlock`.
+
+Make sure the `backup.rom` file gets backed up to an external storage media,
+not the E6430 itself.
+
+With this method, you can probably flash it within 5 minutes. Again, zero
+disassembly required!
+
+How to flash externally
+=========================
+
+Refer to [spi.md](spi.md) as a guide for external re-flashing.
+
+The SPI flash chip shares a voltage rail with the ICH9 southbridge, which is
+not isolated using a diode. As a result, powering the flash chip externally
+causes the ICH9 to partially power up and attempt to drive the SPI clock pin
+low, which can interfere with programmers such as the Raspberry Pi. See
+[RPi Drive Strength](spi.md#rpi-drive-strength) for a workaround.
+
+Have a look online for videos showing how to disassemble, if you wish to
+externally re-flash.
