Take note of the size of the flash chip you will use for SerialICE and set that correctly while in menuconfig.
$ cd SerialICE $ make menuconfig $ make
You can now flash the serialice.rom image. You can execute flashrom on the target machine like this:
$ flashrom -p internal -w serialice.rom
You can also use external programmer devices. In either case, keep a copy of the original mainboard bios image, preferably use a different chip for SerialICE purposes. After programming the flash, do a cold reboot of the target machine.

You need to build a patched QEMU from source, and you will need Lua >= 5.2. To build Qemu you can run the build script that was added by the SerialICE patch:
$ sh build.sh
You are now ready to start using SerialICE. Getting Started provides an intro to using SerialICE, while Log_file explains the output format. Advanced topics like Debugging have information about using gdb with SerialICE targets, and Scripting describes the basics of writing filters to match the hardware.
