    X0="0x`echo $LINE | sed 's|^\([^-]*\)-.*|\1|'`" 

    X1="0x`echo $LINE | sed 's|^[^-]*-\([^ ]*\) .*|\1|'`" 


    R0=$((($(printf %d $X0)/4096))) 

    R1=$((($(printf %d $X1)/4096))) 

if [ $(($(printf %d $X1) % 4096)) -ne 0 ]; then 

     R1=$(($R1 + 1))

    echo "CHUNK: $X0-$X1" 

    dd if=/dev/mem bs=4096 skip=$R0 count=$(($R1 - $R0 )) 

done
