Check the BIOS feature comparison - it has a breakdown of what features are what. For example, it's not "naoni"...it's "noani"...as in no animation. You can figure out that does. The F means it boots from the F partition as opposed to C, so it will look for the dashboard files there. The 256K label just means it's the BIOS size. If the file isn't labeled, just check the size of the BIN file.
