SEE IF YOUR CMOS SETUP HAS A "CUSTOM" OR "USER DEFINABLE" DRIVE TYPE
AVAILABLE. (see below)
Possible translation: 804 cyl, 9 heads, 48 sectors = 177,831,936
Possible translation: 954 cyl, 14 heads, 26 sectors = 177,795,072
PHYSICAL/LOGICAL equivalent to NATIVE/TRANSLATION
!WARNING! - 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.
