  It's giving the same number dots(.) as it is giving on my board, when I 
  test with a normal pc. It just stops after printing some number of dots. 
  No further action is being done any any board either pc or my test 
  board.

  Sorry I did not mention that my board has vme bus as well. But the 
  ethernet devices are pci bus controlled. I guess the bus does not matter 
  since I tried booting different linux versions obviosly which does not 
  have vme bus drivers and they booted perfectly ok. VME is like another 
  bus that comes along with the board apart from PCI. So I am afraid the 
  problem is not regardint the bus interface. Since I tried the vmware 
  floppies on this board and the board is booted up, but ofcourse without 
  any ethernet support. I think the problem lies in the ethernet driver  
  package which I modified and added the lance amd driver, since min 
  confi file in /packages/hal/i386/xycom/v2_0b1/misc/redboot_FLOPPY.ecm 
  does use the ethernet support pacakge. So this might be the only 
  possibility, as far as I know. So any debugging suggestions where my 
  redboot is failing???? I mean how can I know till which point the 
  redboot is booting?? apart from the standard way like changint the 
  ethernet driver till I get the bootig prompt without knowing what 
  happens in between?? Any help would be apprciated.
  
  Thanks a lot for your help once again.
