528 Megabyte
If you set your HDD to Normal mode, the maximum accessible HDD
size will be 528 Megabytes even though its physical size may be
greater than that.
LBA (Logical Block Addressing) Mode
The LBA mode is a new HDD accessing method to overcome the 528
Megabyte limitation. The number of cylinders, heads and sectors shown
on the screen may not be the actual number for the HDD.
During the HDD accessing, the IDE controller will transform the logical
address described by the sector, head and cylinder number into its own
physical address inside the HDD.
The maximum HDD size supported by the LBA mode is 8.4 Gigabytes.
It is obtained by the following formula.

Large Mode
The Large mode is the extended HDD access mode supported by the
G586IPB/E system board. Some IDE HDDs have more than 1024 cylin-
ders without LBA support (in some cases, you may not want the LBA
mode). The system board provides another alternative to support these
kinds of HDD.
