Not during the bootp/DHCP stage, that's only for getting configuration
information.  (It seems a common, but wrong practice, to call the whole
diskless boot process bootp, when that's just the first stage.) But yes
you can tftp a tagged image that contains an init ramdisk, courtesy of
code that Markus Gutschke put into mknbi-linux. See the man page.


As far as I understand ramdisk image is first created and is permanently put in
the bootimage along with the kernel image.
Can I put my application files in this ramdisk? In that case I don't have to
download them seperately. By the way, do I
need initrd? Is so, why? Can't I have just the final ramdisk?

Thanks,
Piyush
