 * MAY REQUIRE FORMATTING AND PARTITIONING SOFTWARE.  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:
       1048 cyl, 16 heads, 63 sectors = 540,868,608

                       DOS operating systems may require a system bios
                       that accepts larger values for the CMOS head
                       parameter which lowers cylinders below 1024:
        524 cyl, 32 heads, 63 sectors = 540,868,608

                       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.

Seagate reserves the right to change, without notice, product 
offerings or specifications. (09/09/96)
