What makes you think so? I think you are wrong.

Given a compressed size of 1.4 MB, the contents of the ramdisk will
be probably in the range of 3...4 MB. Did you really create a ramdisk
16 MB big?

Again, I see no indication that you really have a good, working
ramdisk image. I think you should ask MV support for help.
Alternmatively, you could try using a known-to-work ramdisk image for
a start, for example one from here:

I don't know if it's what you want, but it's what you get. :-)
