Ok, Yes I thik that I can mount, for example, the SST49LF016C. (16Mbit)

I will buy a extra flash chips, and, if possibile, a external hw for
download/reset the firmware.

Sorry but... What is a Rom emulator? Can you post a sample link?

My difficulty is that i start from zero.
For example, I have see on a ALIX tutorial page
(http://www.coreboot.org/PC_Engines_ALIX1.C_Build_Tutorial) but I don't
find any sample or howto for build the firmware...
How I can make for build a firmware with a linux kernel and after
dowload it on a flash chips?
I can following this howto... ?
Thank you for your patience and your collaboration.
