Peripheral Setup - American Megatrends Excalibur PCI User Manual

Peripheral Setup

The WinBIOS Setup options described in this section are selected by choosing the appropriate high-level icon from
the Peripheral Setup screen. Peripheral Setup is selected from the Setup section on the WinBIOS Setup main menu
(see page 59). All displayed icons are described in this section, although the screen display is often all you need to
understand how to set the option.
Programming Option
The settings are Auto or Manual. When set to Auto, the BIOS automatically detects all adapter cards installed in the
system and configures the onboard I/O (serial ports, parallel ports, floppy controllers, and IDE controller)
automatically. All other Peripheral Setup option settings are ignored. Any serial port, parallel port, floppy controller,
or IDE (Integrated Drive Electronics) controller on an adapter card in an expansion slot is configured before onboard
I/O. If Auto is selected, the BIOS also attempts to avoid IRQ conflicts.
If the offboard serial ports are configured to specific starting I/O ports via jumper settings, the BIOS will configure the
onboard serial ports to avoid conflicts. For example, if the default serial port starting I/O ports (serial port1 - 3F8h,
serial port2 - 2F8h, serial port3 - 3E8h, serial port4 - 2E8h) are used, the following configurations are possible:
If Manual is selected, the settings chosen by the end user in Peripheral Setup apply. AMIBIOS reports any I/O
conflicts after displaying the BIOS Configuration Summary Screen, but only if Manual is chosen.
