Thanks for the info,...
However the cp was not there in the ramdisk either,I had to relocate the binaries of cp frm another suitable OS then i was able to use it...
So i will have to do the same with dd as well...
How ever i am not familiar with dd...
So if you could give me the command line of dd?

and also if i use dd,how may i have the privalage of getting the %

Thanks!
