coreinfo is a small informational payload for coreboot. Currently, it can display CPU information, PCI information, coreboot table information, and show an NVRAM dump.

Building coreinfo
libpayload
The coreinfo payload uses libpayload, thus you need to get that first and build it:
$ mkdir foo $ cd foo $ svn co svn://coreboot.org/repos/trunk/payloads/libpayload $ cd libpayload $ make menuconfig $ make
coreinfo
You can then get coreinfo itself and build it:
$ cd .. $ svn co svn://coreboot.org/repos/trunk/payloads/coreinfo $ cd coreinfo $ make menuconfig $ make
The file build/coreinfo.elf is your final coreinfo payload which you can use with coreboot (v2 or v3), either on real hardware or in a QEMU image.
coreboot
Finally, you have to build coreboot (v3 in this example) with coreinfo as payload:
$ cd .. $ svn co svn://coreboot.org/repository/coreboot-v3 $ cp coreinfo/build/coreinfo.elf coreboot-v3/payload.elf $ cd coreboot-v3 $ make menuconfig
Now enter the Payload menu and select Payload type and then An ELF executable payload file. Now exit the menu, save your settings, and build coreboot:
$ make
The file build/coreboot.rom (or build/bios.bin) is your final coreboot v3 image, which also contains the coreinfo payload.
Running coreinfo in QEMU
For running coreboot+coreinfo image in QEMU, but you need a patched version of vgabios-cirrus.bin in your build directory first:
$ cd build $ wget http://www.coreboot.org/images/0/0d/Vgabios-cirrus.zip $ unzip Vgabios-cirrus.zip $ cd ..
You can now run coreinfo in QEMU:
$ qemu -L build -hda /dev/zero -serial stdio
Ready-made coreinfo QEMU image
If you don't want to build libpayload, coreinfo, and coreboot from source, you can also use the ready-made coreinfo QEMU image by following the instructions on that page.
