Internal flashing can also be done with the original Dell BIOS, if the
|
||||||
|
SERVICE_MODE jumper near the PCIe slots is removed. Before flashing,
|
||||||
|
|
||||||
|
rmmod spi-intel-platform
|
||||||
|
|
||||||
|
needs to be run to prevent errors. Once Libreboot is installed, the
|
||||||
|
SERVICE_MODE jumper can be replaced.
|
||||||
|
|
||||||
|
**Note: The Dell BIOS can write EFI variables to flash when shutting
|
||||||
|
down, which could corrupt the newly flashed Libreboot ROM and render
|
||||||
|
the system unusable. To prevent this, after flashing internally from
|
||||||
|
the original Dell BIOS, remove power from the computer instead of
|
||||||
|
shutting it down normally. It's recommended to use a live USB instead
|
||||||
|
of the internal drive to prevent potential filesystem corruption.**
