Type This parameter allows you to 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. Cylinders This parameter specifies your hard disk's number of cylinders, and is automatically set depending on your Type parameter setting. Heads This parameter specifies your hard disk's number of heads, and is automatically set depending on your Type parameter setting. Sectors This parameter specifies your hard disk's number of sectors, and is automatically set depending on your Type parameter setting. Size This parameter specifies the size of your hard disk, in MB. 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 a DOS or Windows 3.x/95/98 environment. Other operating systems require this parameter to be set to Disabled. Hard Disk Block Mode This function enhances disk performance depending on the hard disk in use. If you set this parameter to Auto, the BIOS utility automatically detects if the installed hard disk drive supports the Block Mode function. If supported, it allows data transfer in block (multiple sectors) at a rate of 256 bytes per cycle. To disregard the feature, change the setting to Disabled. NOTE This parameter appears only when you are at the Advanced Level. 24 System Utilities
