Unable to use BootMenu

[Elson Fork <hkelson@hkstar.com>]

While I use the bootmenu, (I have tried on both my own bootp.conf and the author's one)
the client computer side got error on:

1)  It print out "Tag 160 as an unknown".  But refer to the menu, T160 is used for set the
default and timeout value.

2)  When I use Tag192, 193,194 for multi boot, the client only print out the menu for
first one (i.e T192), others (T193,194) won't being printed out for selection.

What is the problem source and how to solve it?
