Coreinfo

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

Downloading and building coreinfo

The coreinfo payload uses libpayload, thus you need to get that first and build it:

$ svn co svn://coreboot.org/repos/trunk/payloads/libpayload
$ cd libpayload
$ make menuconfig
$ make

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, e.g. like this:

$ qemu -L build -hda /dev/zero -serial stdio

(where build/bios.bin is your coreboot v3 image in this case)
