Feel free to make changes.
## Building coreboot
The following commands will help quickly configure and build a project for this board:
```bash
make distclean
touch .config
./util/scripts/config --enable VENDOR_ASROCK
./util/scripts/config --enable BOARD_ASROCK_IMB_1222
make olddefconfig
make
```

## Flashing coreboot
```{eval-rst}
+---------------------+--------------------------+
| Type | Value |
+=====================+==========================+
| Socketed flash | yes |
+---------------------+--------------------------+
| Model | W25Q256JV |
| | MX25L25673G |
+---------------------+--------------------------+
| Size | 32 MiB |
+---------------------+--------------------------+
| Package | WSON-8 8x6 mm |
+---------------------+--------------------------+
| Write protection | chipset PRR |
+---------------------+--------------------------+
| Dual BIOS feature | no |
+---------------------+--------------------------+
| Internal flashing | after flashing coreboot |
+---------------------+--------------------------+
```
The SPI flash can be accessed using [flashrom]. By default, only the
BIOS region of the flash is writable:
```bash
flashrom -p internal -N -w coreboot.rom --ifd -i bios
```
If you wish to change any other region, such as the Management Engine
or firmware descriptor, then an external programmer is required. More
information about this [here](../../tutorial/flashing_firmware/index.md).
