Limit Capacity jumper sets the default cylinder translation
to 4092 to solve issues with certain BIOS that only auto-detect.
Total available sectors are still at full capacity as reported via
Identify Drive data words 52 - 61.  Third party partitioning software
may be needed to achieve full capacity if this option jumper is used.

Set CMOS hard drive setup to Auto-Detect with LBA mode enabled. 

Some systems BIOS have capacity limitations. 
Types that have been identified are:
     a 2.113GB or 4095 cylinder limitation 
     a 3.262GB or 6322 cylinder limitation 
     a 4.22GB  or 8192 cylinder limitation
     a 8.45GB  Standard INT13 limitation (CHS[1024x256x63]x512)
     a 33.8GB or 66,060,287 LBAs limitation
and, if exceeded, may cause the system to hang during boot, 
capacity reduction or it can truncate or wrap the cylinders when 
auto-detect options set in the CMOS. FAT16 based operating systems
are also limited to 8.4GB.  New INT13 Extensions in BIOS and FAT32
based operating systems are both required to acheive full capacity.

DOS 16-bit FAT file system cannot access more than 2.147 Gbytes per 
partition.  FAT32 file system can create single partitions and
logical drives up to 2TB.

Already low-level formatted at the factory.
