# Protectli Vault VP2420
This page describes how to run coreboot on the [Protectli VP2420].
## Required proprietary blobs
To build a minimal working coreboot image some blobs are required (assuming
only the BIOS region is being modified).
```eval_rst
+-----------------+---------------------------------+---------------------+
| Binary file | Apply | Required / Optional |
+=================+=================================+=====================+
| FSP-M, FSP-S | Intel Firmware Support Package | Required |
+-----------------+---------------------------------+---------------------+
| microcode | CPU microcode | Required |
+-----------------+---------------------------------+---------------------+
```
FSP-M and FSP-S are obtained after splitting the Elkhart Lake FSP binary (done
automatically by the coreboot build system and included into the image) from
the `3rdparty/fsp` submodule.
Microcode updates are automatically included into the coreboot image by build
system from the `3rdparty/intel-microcode` submodule.
## Flashing coreboot
### Internal programming
The main SPI flash can be accessed using [flashrom]. Firmware can be easily
flashed with internal programmer (either BIOS region or full image).
### External programming
The system has an internal flash chip which is a 16 MiB soldered SOIC-8 chip.
This chip is located on the top side of the case (the lid side). One has to
remove 4 top cover screws and lift up the lid. The flash chip is soldered in
under RAM, easily accessed after taking out the memory. Specifically, it's a
KH25L12835F (3.3V) which is a clone of Macronix
MX25L12835F - [datasheet][MX25L12835F].
## Working
- USB 3.0 front ports (SeaBIOS, Tianocore UEFIPayload and Linux)
- 4 Ethernet ports
- HDMI, DisplayPort
- flashrom
- M.2 WiFi
- M.2 4G LTE
- M.2 SATA and NVMe
- 2.5'' SATA SSD
- eMMC
- Super I/O serial port 0 via front microUSB connector
- SMBus (reading SPD from DIMMs)
- Initialization with Elkhart Lake FSP 2.0
- SeaBIOS payload (version rel-1.16.0)
- TianoCore UEFIPayload
- Reset switch
- Booting Debian, Ubuntu, FreeBSD
