First of all I use testing version of Debian – wheezy. Clone coreboot repository: git clone cd coreboot; make menuconfig Configure FILO as apayload and use its latest version:

coreboot code effectively I suggest to create tags and cscope database for coreboot. In my personal workspace I’ve got process that I go through before I start work (if you use my workspace configuration which is available @github you can follow below steps directly, if not adjust to your environment): 1. run vim 馃槈 2. :cd /path/to/code 3. s<Tab> (fuzzyfinder -> bookmark dir) 4. si (fuzzyfinder -> change dir) 5. sr (run ctags to generate tags and cscope to build symbol database – ctags -R;cscope -R -q -b -v) After steps above we can start work with code. Run vim in

coreboot directory. Type: :e src/cpu/x86/16bit/ Put cursor over protected_start and press Ctrl-]. If everything goes ok you should jump to build/mainboard/emulation/qemu-x86/bootblock.s line 537. In second article we dive into first phase of coreboot execution in emulated environment.
