; SerialDPT_Finalize
;	Parameters:
;		DS:DI:	Ptr to Disk Parameter Table
;		ES:SI:	Ptr to 512-byte ATA information read from the drive
;	Returns:
;		CF:		Set, indicates that this is a floppy disk
;				Clear, indicates that this is a hard disk
;	Corrupts registers:
;		AX

;
; Note that this section is not under %ifdef MODULE_SERIAL_FLOPPY.  It is important to
; distinguish floppy disks presented by the server and not treat them as hard disks, even
; if the floppy support is disabled.
