                    Limit capacity 陳陳陳陳

On drives less than 33.8GB, 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. On drives greater
than 33.8GB, Limit Capacity jumper changes total available sectors
as reported via Identify Drive data words 60-61 to 33.8GB. The ATA 
Read Native Max and Set Max commands may be used to reset the true 
full capacity. Third party partitioning software may be needed to 
achieve full capacity when using this option jumper.

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 528MB limitation (CHS[1024x16x63]x512 = 528,482,304)
     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. 

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.

FAT16 based operating systems are also limited to 8.4GB.  New 
INT13 Extensions and LBA mode in BIOS and FAT32 based operating 
systems are both required to acheive full capacity.

Other FULL-CAPACITY solutions include third-party drive preparation
software, system BIOS update which supports LBA mode or third
party bios driven host adapters.

Default CHS translation:
     16,383 cyl, 16 heads, 63 sectors = 8,455,200,780
