+* It's safe to use the SPI flasher power, as all devices have a protection

+* Do **NOT** accidently swap pins or power on the board while a SPI flasher
+ is connected. It will permanently brick your device.
+* It's recommended to only flash the BIOS region. In that case you don't
+ need to extract BLOBs from vendor firmware.
+ If you want to flash the whole chip, you need BLOBs when building
+ coreboot.
+* The *Flash layout* shows that by default 3MiB of space are available for

+* If you don't want to touch IFD, ME, GBE you must only flash the 4MiB
+ flash IC. In that case your BIOS region must not exceed 4MiB.
+
+Please also have a look at *TODO* [General Flashrom Usage].
+
+## Splitting the coreboot.rom
+
+To split the coreboot.rom into two images (one for the 8MiB and one for the
+4 MiB flash IC), run the following commands:
+
+ dd of=top.rom bs=1M if=build/coreboot.rom skip=8
+ dd of=bottom.rom bs=1M if=build/coreboot.rom count=8
+
+That give two ROMs for each flash IC.
+
+## Flash layout
+The two flash ICs appear as a 12MiB when flashing internaly.
