Sure, nice check. EA> The "reserved" cluster numbers effectively are just aliases for "bad EA> cluster". If so, why they counted as "valid cluster number"? See: FAT16 starts only from FF6h (4086) clusters (by definition), but how then manage partition, where may reside, say, FF3h (4083) clusters?

I not study SAY yet, but I already see, that SYS uses already prepared (by FORMAT) parameter block. So, this is valid. Why I ask about Hidden field: I earlier seen, as boot sector searches partition table to determine partition start (from "active" record). And I nowhere read that partition start (should) reflected in Hidden field. EA> This broke LBA booting. Is mkdosfs replaces format?
