     Ok, I try this, thank you.

     Yes! Sure, nice check.

     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? Increase cluster
size (by two) and decrease total clusters (to 2042)?

     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.

     Is mkdosfs replaces format?

     Is DISKCOPY may read from file (and thus, it replaces rawrite)? URL?

     What contained (which programs) in ODIN diskette? URL?
