This parameter lets you specify the type of hard disk installed in your system. If you want BIOS to automatically configure your hard disk, select Auto. If you know your hard disk type, you can enter the setting manually. Setting this parameter also sets the Cylinder, Head, Sector, and Size parameters. Cylinder This parameter specifies the number of cylinders of your hard disk, and is automatically set depending on your Type parameter setting. Heads This parameter specifies the number of heads of your hard disk, and is automatically set depending on your Type parameter setting. Sectors This parameter specifies the number of sectors of your hard disk, and is automatically set depending on your Type parameter setting. Size This parameter specifies the size of your hard disk, in MB. Enhanced IDE Features Hard Disk Size > 504 MB When set to Auto, the BIOS utility automatically detects if the installed hard disk supports the function. If supported, it allows you to use a hard disk with a capacity of more than 504 MB. This is made possible through the Logical Block Address (LBA) mode translation. However, this enhanced IDE feature works only under DOS, Windows 3.x, Windows 95, and Windows NT 3.5 and above. Other operating systems require this parameter to be set to Disabled. BIOS Utility 3-13
