2. HDD Modes
The Award BIOS supports 3 HDD modes: NORMAL, LBA and LARGE, also
Auto detect.
NORMAL
Generic access mode in which neither the BIOS nor the IDE controller will
make any transformation during accessing. The maximum number of cylinders,
heads and sectors for NORMAL mode are 1024,16 and 63.
If user sets his 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
A new HDD accessing method overcoming the 528 Megabyte bottleneck. The
number of cylinders, heads and sectors shown in setup may not be the number
physically contained in the HDD.
During HDD accessing, the IDE controller will transform the logical address
described by sector, head and cylinder number into its own physical address
inside the HDD. The maximum HDD size supported by LBA mode is 8.4
Gigabytes.
