Large PC manufacturers like Dell and Hewlett-Packard produce motherboards themselves,
and develop their own BIOS versions. You should always refer to the documentation that
came with your computer for instructions on proper BIOS configuration.
B.2.2
Standard CMOS setup menu
Parameters in the standard CMOS setup menu usually define the geometry of the
hard disk. The following parameters (and values) are available for each hard disk
installed in your PC:
Parameter
Type
Cylinder (Cyl)
Heads (Hd)
Sectors (Sec)
Size (Capacity) MBytes
Mode
(Translation
Method)
For example, to demonstrate the main features of Acronis True Image Home, we
used a Quantum
examples. Its parameters have the following values:
Parameter
Type
Cylinder (Cyl)
Heads (Hd)
Sectors (Sec)
Mode
CHS
Maximum LBA Capacity
In BIOS setup, you can set the Type parameter to User Type HDD (user-defined
type). In this case, you also have to specify the value of the translation mode
parameter, which can be Auto/Normal/LBA/Large.

reserved for user-defined parameters or for
parameters detected by the IDE Auto detection
utility.
Auto value allows for automatic detection of IDE
disk parameters during the boot sequence.

The number of cylinders on a hard disk. For IDE
disks, a logical number of cylinders is specified.
1-16
The number of heads on a hard disk. For IDE
disks, a logical number of heads is specified.
1-63
The number of sectors per track of a hard disk. For
IDE disks, a logical number of sectors is specified.
The capacity of the disk in megabytes. It is
calculated according to the following formula:
Size=(Cyl x Hds x Sct x 512) / 1024 / 1024.
