In previous postcoreboot was configured and installed. Here we try to establish good debugging
environment for it. To create a good emulated environment to debug, research and
learn coreboot few tricks are required. First of all we need to know how to run
our emulated environment (qemu). What I mean by that ?
load coreboot image (-bios option),

(use :e to reload qemu.log file after every instruction), in this file we will
get information about all registers of virtual machine

* Run next instruction (ni command in gdb) and refresh qemu.log, if you get
