Click <Enter> key to enter its submenu: 

 

IDE HDD Auto-Detection 

This item allows you to detect the parameters of IDE drives by pressing the <Enter> 
key. The parameters will automatically be shown on the screen. 

IDE Primary Master 

When set to [Auto], the BIOS will automatically check what kind of IDE drive you 
are using. If you want to define your own drive by yourself, set it to [Manual] and 
make sure you fully understand the meaning of the parameters. Refer to the manual 
provided by the device manufacturer to get the settings right. 

Access Mode 

This item selects the mode to access your IDE devices. Leave this item to its default 
[Auto] settings to let BIOS detects the access mode of your HDD and makes decision 
automatically. 

 

Capacity 

This item automatically displays your HDD size. Note that this size is usually slightly 
greater than the size given by a disk-checking program of a formatted disk. 

NOTE:

 The following [Cylinder], [Head], [Precomp], [Landing Zone], and [Sector] 

items are available when you set the item “IDE Primary Master” to “Manual”.
