Re: tftpboot.img

[Nikita Schmidt <cetus@snowball.ucd.ie>]

tftpboot.img has no structure and consists of three parts: loader, kernel,
and ramdisk image.  It's created by
	make bootpfile INITRD=ramdisk_image_file_name
in linux/arch/alpha/boot/.

Debian scripts do basically the same, except they use a slightly modified
version of the loader (bootp.c) which passes `root=/dev/ram' argument to
the kernel (this can still be overridden through boot_osflags).

I think these scripts are somewhere in the boot-floppies source; they also
build the root image which is then passed on to the script that makes
tftpboot.img.
