Problem with some diskless client

[Mohd-Hanafiah Abdullah <napi@cel.mimos.my>]

One diskless client machine could boot off the server by means of a bootrom
floppy.  The bootrom sends something and the server responds accordingly.

Strangely, using the same bootrom floppy on another diskless client machine
using the same type of ethernet-card (3Com 3C509B), there is no communication
at all between the bootrom and the server.  Only dots come out.  It has also
been defined in the file /etc/bootptab.  The LED at the hub doesn't even lit
for it.  The card works fine when I use Windows95 on the same machine and the
same cable though, and the LED at the hub lits up in this case.

Please help.  Thanks.
