I like to use either Flash memory or DOC and not both. I want to know if I have my Flash memory or DOC mapped to lower address what modification should I do to the linuxbios coding. like regarding setiing the RAMBASE, ROMBASE...........The power-up reset address for the Geode is FFFFFFF0h, you can't change that.
Your only strapping options are:
(1) Enable either an 8 bit or 16 bit boot ROM access
(2) Enable either a LPC or ISA boot ROM access.

Are you using NAND Flash or DOC or both ? Are you trying to boot from the DOC?
