[LinuxBIOS] Mount linux elf image for netboot as loop device

The mkelfImage would package initrd with the kernal. does the mount it as a
loop device would allow user to take look what's in there?

If mount as loop device would not work, do you think there is a way to look
what's in the elf image after it has been made?

mkelfimage doesn't make a filesystem as far as I know, and only puts
the kernel into a format that the linuxbios expects to find so it can
load it into ram and jump to it. What you are asking to do is about as
the same as mounting a compiled program as a filesystem. You can't do
'mount -o loop /bin/bash /mnt/loop' anymore then you can mount the
kernel file.
