If you store that spare rom in a safe place and only use it to boot from, you don't need an external programmer. A often used trick to ease removal is to glue a handle to the chip: http://www.settoplinux.org/images/thumb/5/56/Push_pin2.jpg/500px-Push_pin2.jpg > >> 2.

Then replace the names but keep the (C) copyright headers. 5) "cd" back into the top source dir and run "make menuconfig ; make" (or make xconfig/gconfig) where you select the axiomtek mainboard. Exit the menu, save the configuration and run "make"; after a minute or so you should have the file build/coreboot.rom which you'll have to program into the first chip. 6) Make sure that you have stored the spare rom in a safe place, then download, compile and install flashrom: http://www.flashrom.org/Downloads#Installation_from_source http://www.coreboot.org/Developer_Manual#How_to_support_a_new_board > I have some C knowledge, but I would really need help, and some people to > show me the way what and where to change in the code at least to make it > work? > >> 5.
