First thing to do is to use tcpdump in order to see what was the last  
thing the JavaStation did before resetting. First it should load the  
bootloader via tftp ( that's the only thing which needs to be in / 
tftpboot - swap, root and kernel can be pretty much anywhere you want,  
even on a different machine ). The boot loader should do another round  
of DHCP requests to find where to find the kernel ( it needs to be  
accessible via nfs so a convenient place is the javastation's root  
filesystem ). After that you should see a lot of nfs traffic. Then the  
kernel will do yet another dhcp lookup to find its root, swap, IP etc.
I don't remember wether you need to link the loader to the client's IP  
in hex. Anyway, you should see hexadecimal numbers counting when the  
loader is loaded over tftp ( and you should see the tftp traffic in  
tcpdump ). Since you didn't mention any useful detail it's impossible  
to even guess what's (not) going on.

have fun
