**If you haven't bought an R400 yet: the [Dell Latitude
|
|
|
|
|
E6400](../../news/e6400.md) is much easier to flash; no disassembly required,
|
|
|
|
|
it can be flashed entirely in software from Dell BIOS to Libreboot. It is the
|
|
|
|
|
same hardware generation (GM45), with same CPUs, video processor, etc.**

It is believed that all or most R400 laptops are compatible. See notes
|
|
|
|
|
about [CPU
|
|
|
|
|
compatibility](../install/r400_external.html#cpu_compatibility) for
|
|
|
|
|
potential incompatibilities.
|
|
|
|
|
|
|
|
|
|
There are two possible flash chip sizes for the R400: 4MiB (32Mbit) or
|
|
|
|
|
8MiB (64Mbit). This can be identified by the type of flash chip below
|
|
|
|
|
the palmrest: 4MiB is SOIC-8, 8MiB is SOIC-16.

|
*The R400 laptops come with the ME (and sometimes AMT in addition)
|
2022-11-14 02:31:12 +00:00
|
|
|
before flashing libreboot. libreboot disables and removes it by using a
|
2021-05-18 12:21:48 +00:00
|
|
|
modified descriptor: see [../install/ich9utils.md](../install/ich9utils.md)*

EC update {#ecupdate}
|
|
|
|
|
=========
|
|
|
|
|
|
|
|
|
|
It is recommended that you update to the latest EC firmware version. The
|
|
|
|
|
[EC firmware](../../faq.md#ec-embedded-controller-firmware) is separate from
|
2022-11-14 02:31:12 +00:00
|
|
|
libreboot, so we don't actually provide that, but if you still have
|
2021-05-18 12:21:48 +00:00
|
|
|
Lenovo BIOS then you can just run the Lenovo BIOS update utility, which
|
|
|
|
|
will update both the BIOS and EC version. See:
|
|
|
|
|
|
|
|
|
|
- [../install/#flashrom](../install/#flashrom)
|
|
|
|
|
- <http://www.thinkwiki.org/wiki/BIOS_update_without_optical_disk>
|
|
|
|
|
|
|
|
|
|
NOTE: this can only be done when you are using Lenovo BIOS. How to
|
2022-11-14 02:31:12 +00:00
|
|
|
update the EC firmware while running libreboot is unknown. libreboot
|
2021-05-18 12:21:48 +00:00
|
|
|
only replaces the BIOS firmware, not EC.
|
|
|
|
|
|
|
|
|
|
Updated EC firmware has several advantages e.g. bettery battery
|
|
|
|
|
handling.
|
|
|
|
|
|
|
|
|
|
The R400 is almost identical to the X200, code-wise. See
|
|
|
|
|
[x200.md](x200.md).
|
|
|
|
|
|
|
|
|
|
TODO: put hardware register logs here like on the [X200](x200.md) and
|
|
|
|
|
[T400](t400.md) page.
