1 # Protectli Vault VP2420
3 This page describes how to run coreboot on the [Protectli VP2420].
8 ## Required proprietary blobs
10 To build a minimal working coreboot image some blobs are required (assuming
11 only the BIOS region is being modified).
14 +-----------------+---------------------------------+---------------------+
15 | Binary file | Apply | Required / Optional |
16 +=================+=================================+=====================+
17 | FSP-M, FSP-S | Intel Firmware Support Package | Required |
18 +-----------------+---------------------------------+---------------------+
19 | microcode | CPU microcode | Required |
20 +-----------------+---------------------------------+---------------------+
23 FSP-M and FSP-S are obtained after splitting the Elkhart Lake FSP binary (done
24 automatically by the coreboot build system and included into the image) from
25 the `3rdparty/fsp` submodule.
27 Microcode updates are automatically included into the coreboot image by build
28 system from the `3rdparty/intel-microcode` submodule.
32 ### Internal programming
34 The main SPI flash can be accessed using [flashrom]. Firmware can be easily
35 flashed with internal programmer (either BIOS region or full image).
37 ### External programming
39 The system has an internal flash chip which is a 16 MiB soldered SOIC-8 chip.
40 This chip is located on the top side of the case (the lid side). One has to
41 remove 4 top cover screws and lift up the lid. The flash chip is soldered in
42 under RAM, easily accessed after taking out the memory. Specifically, it's a
43 KH25L12835F (3.3V) which is a clone of Macronix
44 MX25L12835F - [datasheet][MX25L12835F].
