## Installation instructions
Doc/mb/lenovo/Sandy_Bridge_series.md: Clarify installation Unlike Ivy Bridge series, there isn't a method to flash coreboot internally when running vendor firmware (yet). Until someone finds a way to bypass flash protections, the first flash has to be done externally.

Flashing coreboot for the first time needs to be done using an external
programmer, because vendor firmware prevents rewriting the BIOS region.

## Flash layout
There's one 8MiB flash which contains IFD, GBE, ME and BIOS regions.
On Lenovo's UEFI the EC firmware update is placed at the start of the BIOS
region. The update is then written into the EC once.
