# Portwell PQ7-M107
This page describes how to run coreboot on the [Portwell PQ7-M107].
PQ7-M107 are assembled with different onboard memory modules:
Rev 1.0 Onboard Samsung K4B8G1646D-MYKO memory
Rev 1.1 and 1.2 Onboard Micron MT41K512M16HA-125A memory
Rev 1.3 Onboard Kingston B5116ECMDXGGB memory
Use 'make menuconfig' to configure `onboard memory manufacturer` in Mainboard
menu.
## Required blobs
This board currently requires:
fsp blob 3rdparty/fsp/BraswellFspBinPkg/FspBin/BSWFSP.fd
Microcode Intel Braswell cpuid 1046C4 version 410
(Used pre-built binary retrieved from Intel site)
## Flashing coreboot
### Internal programming
The main SPI flash can be accessed using [flashrom].
### External programming
The system has an internal flash chip which is a 8 MiB soldered SOIC-8 chip.
This chip is located on the top middle side of the board. It's located
between SoC and Q7 connector. Use clip (or solder wires) to program
the chip.
Specifically, it's a Winbond W25Q64FW (1.8V), whose datasheet can be found
[here][W25Q64FW].
## Known issues
- The PQ7 module contains Q7 connector only. Depending on the carrier
serial/video/pcie ports might be available.
## Untested
- hardware monitor
- SDIO
- Full Embedded Controller support
## Working (using carrier)
- USB
- Gigabit Ethernet
- integrated graphics
- flashrom
- external graphics
- PCIe
- eMMC
- SATA
- serial port
- SMBus
- HDA (codec on carrier)
- initialization with FSP MR2
- SeaBIOS payload (version rel-1.11.0-44-g7961917)
- Embedded Linux (Ubuntu 4.15+)
