ALSO, CHECK TO SEE IF YOUR CMOS SETUP HAS A "CUSTOM" OR "USER DEFINABLE" DRIVE TYPE AVAILABLE. (see below) Possible translations: This translation is generally acceptable, as is, for non-DOS operating systems: 2,098 cyl, 16 heads, 63 sectors = 1,082,769,408 DOS operating systems may require a translation that uses larger values for the CMOS head parameter which lowers cylinders below 1024: 524 cyl, 64 heads, 63 sectors = 1,081,737,216 Other FULL-CAPACITY solutions for DOS operating systems include third-party drive preparation software, system BIOS which supports LBA mode or bios driven host adapters. Otherwise, capacity may be limited to: 1024 cyl, 16 heads, 63 sectors = 528,482,304 Note: A "custom" or "user-defined" 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)". Already low-level formatted at the factory. Since a User-definable or Custom translation geometry may be used, it is imperative that the values be written down and kept with your permanent records for retrieval in the event of CMOS battery failure.
