I am getting broken hardlinks and "permission denied" while copying under
cygwin Unix/Linux type "fadsroot" files from Arabella CD-ROM (supplied with
the PQ2FADS-VR board with MPC8275 - PPC arch ).

I was advised that: "fadsroot must be copied exactly, any error
message probably is a result of the above mentioned incompatibilities  and
the resulting FS would be broken."

Currently (having broken links and may be having other problems associated
with using Windows NFS on PC  laptop as Linux root FS) my board fails at the
end of the U-boot:

**************
.....
Kernel command line:
 root /dev/nfs rw nfsroot=192.168.1.100:/home/apovolot/fadsroot

.....

=> printenv
bootdelay=5
bootcmd=bootm 200000
ipaddr=192.168.1.103
serverip=192.168.1.100
ethaddr=08:00:17:00:00:03
baudrate=19200
stdin=serial
stdout=serial
stderr=serial
bootargs=root /dev/nfs rw nfsroot=192.168.1.100:/home/apovolot/fadsroot


What would be the recommended course of actions ?
Should I manually create softlink instead of each broken hardlink ?
What is the solution for "permission denied" files ?

***************
I also tried "read only" nfs mounting from Arabella's CD-ROM itself (by
modifying 'bootargs" in U-boot environment):

bootargs=root /dev/nfs ro nfsroot=192.168.1.100:/E/fadsroot

In this case booting hangs ...
