18 Chapter 3 BIOS Setup Utility
Figure 3.3 IDE Primary Master Submenu
IDE HDD Auto-Detection
Press Enter while this item is highlighted if you want the Setup Utility to automatically detect and configure a hard
disk drive on the IDE channel.
IDE Primary/Secondary Master/Slave
If you leave this item at Auto , the system will automatically detect and configure any IDE devices it finds. If it fails to
find a hard disk, change the value to Manual and then manually configure the drive by entering the characteristics of
the drive in the fields described below:
• Capacity – displays the capacity of the HDD in megabytes (MB).
• Cylinder – indicates the number of cylinders that the HDD has. A cylinder is the sum total of all tracks that are
in the same location on every disk surface.
• Head – displays the number of heads in the HDD. A head is a device that reads and writes data on the hard
disk.
• Precomp – displays the track where precompensation is initiated. Precompensation is a feature whereby the
HDD uses a stronger magnetic field to write data in sectors that are closer to the center of the disk. In CAV
recording, in which the disk spins at a constant speed, the sectors closest to the spindle are packed tighter than
the outer sectors.
• Landing Zone – displays the location of the safe non-data area on a hard disk that is used for parking the read/
write head.
• Sector – displays the number of sectors available on the HDD. A sector is the smallest unit of storage space on
a disk.
NOTE
If you are setting up a new hard disk drive that supports LBA mode, more than
one line will appear in the parameter box. Choose the line that lists LBA for an
LBA drive.
