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.
