That will vary wildly, depending on the Flash technology. The
HOWTO's I found there seemed to cover what to do if you had
a FLASH that emulated an IDE drive. Essentially just copy
to the drive mounted temporarily as a slave device on the
first IDE channel, make sure you have the boot pointers
set up properly, then shutdown the system and change the
drive over to primary and boot. Most of the other info
is how to put together an initial ramdisk (initrd) image,
etc., so that you can unpack an rootdisk image from the
FLASH and run.
My problem is that the particular board set I'm working
with has a plain 'ol Flash part, with no particular
support from the BIOS to make it look like a drive.
The BIOS does know how to grab an image from the FLASH,
dump it into memory, and jump to it, though. The
trick is getting the stuff into the FLASH in the first
place. I have some QNX utilities that we wrote to
do this, but it's annoying (at best) to have to change
a system over to booting from a QNX drive (or the
QNX flash) only to FTP a new Linux kernel onto the
system, to copy into the flash, only to have that
one fail, reboot, retry, etc. ad infinitum.
Right now, lack of available time to work this problem
is really the only thing stopping me from wrestling
this particular problem to the floor and besting it... 8-)

Thanks Dave. I couldn't find much help there though. I am in need of
steps to load the linux kernel image onto the flash memory.

Whoops. You are correct. That's what I get
for stating something from memory, instead
of double-checking the links...
Thanks,

Ooops,
i am not sure it is on rick's http://linuxdevices.com...
