Are the linux kernels build with a MOP header on them? AIUI MOP needs a 512
byte (or so) header which describes the file. If you try to boot a kernel
without it you will get messages something like that.
I'd like to boot my 2100 using MOP rather than tftp, not because the box won't
actually do tftp but because Linux 2.4 generates UDP headers that it doesn't
like :(
I haven't tried the NetBSD kernels since I moved to Linux 2.4 and tftp broke. I
know they have a mop header builder for kernels but I think I've only seen it
used for their VAX port, VAXes generally will only netboot using MOP.
