Erm... I'm not really sure how to answer this...
Is that supposed to be the firmware version from one of the Sandisk Sansa players? If so, exactly which model is it from? If it's from one of the supported models (listed on the front page,
www.rockbox.org) then Rockbox Utilty can be used to install Rockbox on your player. The firmware version is not all that important aside from helping to identify what version (v1 starting with 01 or v2 starting with 03, in the case of the Sansa e200 models, not too sure about the other ones...) your player is, beyond that the actual version number is irrelevant as Rockbox uses no part of the OF to do anything while it's being used.
