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

* 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:
16,383 cyl, 16 heads, 63 sectors = 8,455,200,780

DOS operating systems may require a translation
that uses larger values for the CMOS head
parameter which lowers cylinders below 1024:
1023 cyl, 256 heads, 63 sectors = 8,447,459,328

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

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)
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.
