OnBoard FDC 
Set this option to Enabled to enable the floppy drive controller on the 
motherboard.  The settings are Auto (AMIBIOS automatically determines if 
the floppy controller should be enabled), Enabled, or Disabled. 
 
OnBoard Serial PortA/B 
This option specifies the base I/O port address of serial port A.  The 
settings are Auto (AMIBIOS automatically determines the correct base I/O 
port address), Disabled, 3F8h, 2F8h, 2E8h, or 3E8h. 
 
OnBoard Parallel Port 
This option specifies the base I/O port address of parallel port on the 
motherboard.  The settings are Disabled, 378h, 278h, or 3BCh. 
 
 
Parallel Port Mode 
This option specifies the parallel port mode. 
The settings are Normal, Bi-Dir, EPP, or ECP. 
Normal: The normal parallel port mode is used. 
Bi-Dir: Use this setting to support bi-directional transfers on the parallel 
port. 
EPP: The parallel port can be used with devices that adhere to the 
Enhanced Parallel Port (EPP) specification.  EPP uses the existing parallel 
port  signals to provide asymmetric bi-directional data transfer driven by  the 
host device. 
ECP: The parallel port can be used with devices that adhere to the 
Extended Capabilities Port (ECP) specification.  ECP uses the DMA protocol 
to achieve data transfer rates up to 2.5 Megabits per second.  ECP provides  
symmetric bi-directional communication. 
 
Parallel Port IRQ 
This option specifies the IRQ used by the parallel port.  The settings are 
Auto, (IRQ) 5, (IRQ) 7. 
 
Parallel Port DMA Channel 
This option is only available if the setting for the Parallel Port Mode option is 
ECP.  This option sets the DMA channel used by the parallel port.  The 
settings are DMA Channel 0, 1, or 3. 
 
On-Chip IDE 
This option specifies the IDE channel used by the onboard IDE controller 
The settings are Disabled, Primary, and Secondary.
