The Award® BIOS supports 3 HDD modes:
NORMAL, LBA & LARGE.
1. Normal mode
Generic access mode in which neither the BIOS nor the IDE controller will make
any transformations during accessing.
The maximum number of cylinders, head & sectors for normal mode are
1024, 16
& 63.
No. Cylinder (1024)
X No. Head (16)
X No. Sector (63)
X No. Per Sector (512)
528 MB
If user set this HDD to normal mode, the maximum accessible HDD size will be
528 MB even though its physical size may be greater than that!
2. LBA (Logical Block Addressing) Mode
A new HDD accessing method to overcome the 528 MB bottleneck. The number
of cylinders, heads & 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 & cylinder into its own physical
address inside the HDD.
The maximum HDD size supported by LBA mode is 8.4 GB which is obtained by
the following formula:
No. Cylinder (1024)
X No. Head (255)
X No. Sector (63)
X No. Bytes Per Sector (512)
8.4 GB
