Hi Chris, The MSP430 used on the Shimmers only has 256 bytes of information memory in total.
See the comment at the start of InternalFlashC.nc for the explanation as to why you are limited to 128 bytes ( http://code.google.com/p/tinyos-main/source/browse/trunk/tos/platforms/shimmer/chips/msp430/InternalFlashC.nc). I don't know of any component that allows you to use all 256 bytes, but it should be very straight forward for you to modify InternalFlash.write() in the mentioned file to allow you to do so (you'll just need to write 128 byte blocks instead byte level writes).
