<tt>Etherboot and gPXE can function in similar scenarios. Both can
communicate with a DHCP service to obtain PXE parameters, such as an IP
address and a boot file.<br>

<tt>I believe that you can load Linux 2.4.x kernels from gPXE.<br>

<tt>A DOS floppy image can be loaded with gPXE -> MEMDISK, where
MEMDISK is loaded as a "kernel" by gPXE. The floppy image is supplied
as the initrd. MEMDISK will then take the initrd and emulate a floppy
disk and boot it. Assuming that the DHCP service provides the
next-server DHCP option to the gPXE client, you could do something like
the following from the gPXE CLI (and which could be adapted to a
script).<br>
<br>
gPXE> initrd dosimg.vfd<br>
...ok<br>
gPXE> chain memdisk<br>

<tt>Could you please describe what the end goal is? There might be a
way to accomplish it without using wrappers or your nbi.img. Will you
have a mixture of both older Etherboot clients as well as newer gPXE
clients? What's going to be booted? A Linux OS? DOS? I apologize if
I've missed these details.<br>
