Hey, I did almost exactly the same thing about 6 months ago...BUT I could
never figure out the format of the file it wanted to TFTP in. Can you provide
more details of the file "bootlinux" you are booting from? Is it a simple
vmlinuz or have you "wrapped it" in something else? I kept getting an error
message after DHCP had done its stuff and after TFTP had started up saying
something about how the loaded file was not in the correct format (or
something similar).
