I will try it as soon as I get home.

My problem is that I can't build a kernel that would be loaded over the 
network with CoLo or builtin bootloader. Somehow the kernels that work 
from hard disk do not work when loaded over the network. The difference 
is that from hard disk they are booted with ntbsd bootloader and from 
the network with colo or builtin bootloader.

Kernel 1.6.1 that is on the restore cd can be booted with colo. Also all 
the GENERIC kernels I tryed including 3.0, 2.1, 1.6.2, booted with colo. 
Some to the root mounting others to some earlier point.

Is there any debug info I can enable in the kernel to help to pinpoint 
the problem?  Also is there any place I could read about kernel in more 
details? I am pretty familiar with linux kernel and embedded development 
, just need some pointers.


Thanks,
Alex
