Option [Auto] [Enabled] [Disabled] Description BIOS will automatically determine whether to enable the onboard Floppy controller or not. Enables the onboard Floppy controller. Disables the onboard Floppy controller. Onboard Serial Port A/B These items specify the base I/O port addresses of the onboard Serial Port 1 (COM A)/Serial Port 2 (COM B). Please note that Serial Port B is for IR control. Selecting [Auto] allows AMIBIOS to automatically determine the correct base I/O port address. Settings: [Auto], [3F8/COM1], [2F8/COM2], [3E8/COM3], [2E8/COM4] and [Disabled]. Serial Port B Mode This item sets the operation mode for Serial Port B. Settings: [Normal], [1.6uS], [3/16 Baud] and [ASKIR] (the last three operation modes are setting options for IR function). IR Duplex Mode This setting controls the operating mode of IR transmission/reception. Setting options: [Full Duplex], [Half Duplex]. Under [Full Duplex] mode, synchronous, bi-directional transmission/reception is allowed. Under [Half Duplex] mode, only asynchronous, bidirectional transmission/reception is allowed. IR Pin Select Set to [IRRX/IRTX] when using an internal IR module connected to the IR connector. Set to [SINB/SOUTB] when connecting an IR adapter to COM B. Onboard Parallel Port This field specifies the base I/O port address of the onboard parallel port. Selecting [Auto] allows AMIBIOS to automatically determine the correct base I/O port address. Settings: [Auto], [378], [278], [3BC] and [Disabled]. Parallel Port Mode This item selects the operation mode for the onboard parallel port: [ECP], [Normal], [BiDir] or [EPP].
