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 and Windows 3.x, 95 environments. 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.
