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.
