Primary Master/ Primary Slave/ Secondary Master/ Secondary Slave: Hard Disk Drive Setting. 

 
Cyin: This field configures the number of cylinders. Refer to the drive documentation to determine the 
correct value. To make changes to this field, set the Type field to [User Type HDD] and the Translation 

Method field to [Manual]. 
 

Head: This field configures the number of read/write heads. Refer to the drive documentation to determine 
the correct value. To make changes to this field, set the Type field to [User Type HDD] and the Translation 

Method field to [Manual]. 
 
WPcom: Write Precompensation Cylinder. Older hard drives have the same number of sectors per track at 

the innermost tracks as at the outermost tracks. This means that the data density at the innermost tracks is 
higher and thus the bits are lying closer together. Starting with this Cyl# until the end of Cyl#s the writing 

starts earlier on the disk. In modern Hard Devices such as SCSI this entry is useless. For IDE hard drives it 
is not necessary to enter a WP cylinder. The IDE HDD will ignore it for it has its own parameters inboard. 

Sec: This field configures the number of sectors per track. Refer to the drive documentation to determine 
the correct value. To make changes to this field, set the Type field to [User Type HDD] and the Translation 

Method field to [Manual]. 
 

LBA: Select the hard disk drive type in this field. When Logical Block Addressing (LBA) is enabled, the 28-bit 
addressing of the hard drive is used without regard for cylinders, heads, or sectors. Note that LBA Mode is 
necessary for drives with more than 504MB storage capacity. 

 
Blk: This option allows you to enable or disable the Block Mode that is a performance enhancement that 

allows the grouping of multiple read or write commands over the IDE/ATA interface. The settings are 
Enable or Disable. 

PIO: This option lets you set a PIO (Programmed Input/Output) mode for the IDE device. Modes 0 through 
4 provide successive increase in performance.
