On systems that do not support size suffixes (such as
Linux dd might), you need to "manually multiply", for
example:

	dd if=<image> of=<device> bs=1024k

Or, if the "k" suffix isn't supported,

	dd if=<image> of=<device> bs=1048576

Note that this unit has to be converted as 2^10 = 2014
(instead of 10^3 = 1000). See "man dd" to check what
your version of dd implements.

The command is correct, just adjust the bs= parameter accordingly.
