Advanced Pio Mode; Hard Disk Size > 504Mb - Acer 930 Bios Manual

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 to 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 and Windows 3.x, Windows 95
environments. Other operating systems require this parameter to be set to
Disabled
