Otherwise, capacity may be limited to: 1024 cyl, 16 heads, 63 sectors = 528,482,304 Note: A "custom" or "user-definded" CMOS drivetype may ask for a numerical value for the Write Precompensation cylinder and for the Landing Zone cylinder. A basic rule-of-thumb for drive models that do not require the old Write Precomp technique or a Landing Zone because they are Auto- Parking is to add 1 to the cylinder value being used. As an example: If cylinders equaled 820, then both Write Precomp and Landing Zone would be entered as 821. Some BIOS will convert this to 65535 or -1, which are functionally equivalent to "none (not used)".
