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
|

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.
