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.
Advanced PIO Mode
When set to Auto, the BIOS utility automatically detects if the installed hard disk
supports the function. If supported, it allows for faster data recovery and
read/write timing that reduces hard disk activity time. This results in better hard
disk performance. To disregard the feature, change the setting to Disabled.
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, enhanced IDE feature works only
under DOS, Windows 3.x, and Windows 95/98 environments. Other operating
systems require this parameter to be set to Disabled.
