From 0ec903a73bd76e2f664259258933c42ce722b0f2 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Fri, 22 Jan 2021 19:14:07 +0100 Subject: 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.
