- TPM;
- disabling ME with me_cleaner [2];

Payload:
- Linux as payload;
- LinuxBoot;
- SeaBIOS;
- edk2 [3].

Bootable OS:
- Ubuntu 22.04 (Linux 6.5.0-15-generic);
- Ubuntu 24.04 (Linux 6.8.0-41-generic);
- Microsoft Windows 10 Pro (10.0.19045.4780, 22H2 2022);

Unknown/untested:
- USB3.0 in M.2 Key-B 3042/3052 slot;
- eDP/LVDS;
- PCIe riser cards;
- SPDIF.

There is no schematic/boardview, reverse engineering only.
This port is based on system76/bonw14 because it has a similar topology.

+## 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
+```

+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).
