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

[edit] Building coreinfo
libpayload and coreinfo are in the payloads/ directory of the coreboot tree. If you have already checked out the tree, you can skip the git clone steps below.
[edit] libpayload
The coreinfo payload uses libpayload, thus you need to get that first and build it:
$ git clone http://review.coreboot.org/p/coreboot $ cd coreboot/payloads/libpayload $ make menuconfig $ make install
[edit] coreinfo
You can then get coreinfo itself and build it:
$ cd coreboot/payloads/coreinfo $ make menuconfig $ make
The file build/coreinfo.elf is your final coreinfo payload which you can use with coreboot, either on real hardware or in a QEMU image.
[edit] coreboot
Finally, you have to build coreboot with coreinfo as payload:
$ cp coreboot/payloads/coreinfo/build/coreinfo.elf coreboot/payload.elf $ cd coreboot $ make menuconfig
Now enter the Payload menu and select Payload type and then An ELF executable payload file. Then, exit the menu, save your settings, and build coreboot:
$ make
The file build/coreboot.rom is your final coreboot image, which also contains the coreinfo payload.
[edit] Running coreinfo in QEMU
For running coreboot+coreinfo image in QEMU, you need
1 Previously described steps (build coreboot image for QEMU)
2 Patched version of vgabios-cirrus.bin in your build directory:
$ 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-system-i386 -L build -hda /dev/zero -serial stdio
[edit] 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.
