No actually I haven't looked at this utility.
National provides a Linux kernel device driver to talk to flash
on my development board. Their own utilities use this driver.
It provides lseek, read, and write calls to access the flash devices.
I ended up putting Linux on my development board using the
original Insyde BIOS and then wrote a Linux user space program
that utilizes that driver to program the Flash myself from the linux
I've switched to Elfboot now and still not quite right.
Does the zkernel_start have to point to the beginning of the
romimage in flash where the kernel actually is?
Here's an excerpt:
Welcome to elfboot, the open sourced starter.
January 2002, Eric Biederman.
200:init_bytes() - zkernel_start:0xffe00000 zkernel_mask:0x0000ffff
Searching for 16 byte tags
63:rom_read_bytes() - overflowed source buffer. max_block = 31
init_bytes found 0 tags
Cannot Load ELF Image
Thanks for all the help so far,

I am also working on a board that integrates the Geode SC2200/SC1200
chip. I am not sure if I can answer your questiuon, but I am
interrested in how you programed your flash. I was planning on trying
the /dev/bios utility before I attemted to do it on my own. Have you
look at this utility?
