Casio PVOS SDK ships with the OS in a single file, called BIOS. Caleid SDK comes chunked into multiple segments, each under 64KB (totally normal thing for an x86 embedded device, I suppose).

CPU.00/01 have the initial BIOS/bootloader; I haven't diff'ed it with the code from NC3022, but I suppose it is going to be somewhat different. There's very little code in it, though.

Then there's LIBINT; probably library for internalisation. Could it be a file that is different between Japanese and Western models? It has huge tasty bitmaps of numbers and days of week.
