5.6.2 Load Setup Defaults
User can load the Setup option settings by selecting the Fail-Safe item from the
Default section of the BIOS Setup main menu.
The Fail-Safe settings provide far from optimal system performance, but are the most stable settings. Use this
option as a diagnostic aid if the system is behaving erratically.

5.7 INTEGRATED PERIPHERALS
This section is designed to configure the peripheral features.
Integrated Peripherals
IDE HDD Block Mode
This option allows your hard disk controller to use the fast block mode to transfer data to and from your hard disk
drive (HDD).
Enabled IDE controller uses block mode.
Disabled IDE controller uses standard mode.
IDE PIO
IDE hard drive controllers can support up to two separate hard drives. These drives have a master/slave
relationship, which is determined by the cabling configuration used to attach them to the controller. Your system
supports one IDE controller – a primary and a secondary – so you have the ability to install up to four separate
hard disks.
PIO means Programmed Input/Output. Rather than have the BIOS issue a series of commands to affect a transfer
to or from the disk drive, PIO allows the BIOS to tell the controller what it wants and then let the controller and the
CPU perform the complete task by them. This is simpler and more efficient (and faster). Your system supports
five modes, numbered from 0 to 4, which primarily differ in timing. When Auto is selected, the BIOS will select the
best available mode.
