Help with GRUB and Network Boot

[Ivan Passos]

Hello,

I'm playing with GRUB (v0.91)and its network boot, and it works
beautifully. However, as of now, I was only able to make it work with two
separate files (kernel and initrd). I'd like to get it to work with one
single file (that contains kernel + initrd), but I don't know how to
create this file. Can someone please help me?!?!

More details ...

With GRUB (the version I use is 0.91), you may boot via network by adding
something like this to your menu.lst:

Title Network Boot
ifconfig --address=$LOCAL_ADDR --server=$TFTP_SRV_ADDR
root (nd)
kernel $KERNEL_IMG root=/dev/ram0
initrd $INITRD_IMG


This works like a charm. As a next step, I'd like to have one single file
that contains both the kernel image and the initrd image, just because
distributing one file is easier than two ... :)

In this case, I'm looking for the following menu.lst entry:

Title Network Boot
ifconfig --address=$LOCAL_ADDR --server=$TFTP_SRV_ADDR
root (nd)
kernel $NEW_KERNEL_IMG root=/dev/ram0

, where $NEW_KERNEL_IMG contains both $KERNEL_IMG and $INITRD_IMG.

I _believe_ this is possible because when you boot from a floppy, both the
kernel and the initrd are in the floppy, so I guess that the generation of
the file I want is similar to the way the boot floppies are generated. I'm
not sure about that though ...

Any help would be highly appreciated.

Thanks in advance!!

Later,
Ivan
