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

MAY REQUIRE FORMATTING AND PARTITIONING SOFTWARE TO ACHIEVE FULL
CAPACITY. 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
