Introduction
|
|
============
|
|
|
|
**Libreboot 20231021 and releases newer than this have ROMs available for
|
|
Dell Latitude E5520.**
|
|
|
|
ROM images for Dell Latitude E5520 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: [E5520 installation
|
|
instructions](../install/e6430.md)**
