Good idea, also > the boards I am working with all have a doc socket already. Bear in mind you can use a Millennium to replace BIOS flash too -- if you're arguing on grounds of cost, you need to compare the cost of your NOR flash _and_ the NAND with the cost of a DiskOnChip Millennium of similar size. > Originally I was thinking about using etherboot as a base to start from, > add support for booting images from a raw flash partition.

If you want to boot a kernel from a JFFS2 partition on NAND, it'll be a lot of work to make it happen in etherboot. -- dwmw2
