Onboard FDC [Auto]
[Auto] allows the motherboard to detect whether you have a separate floppy disk
drive controller (FDC). If a separate card is detected, the onboard FDC will be dis-
abled. If no separate card is detected, the onboard FDC will be enabled. When [En-
abled] is selected, you may connect your floppy disk drives to the onboard floppy
disk drive connector without using a separate controller card. If you want to use a
different controller card to connect the floppy disk drives, set this to [Disabled].
OnBoard Serial Port1 / OnBoard Serial Port2 [Auto]
These fields allow you to set the addresses and COM ports for the onboard serial
connectors. [Auto] detects whether you are using any devices on these connectors.
If yes, the BIOS program automatically assigns addresses and COM ports for these
connectors. You may also select addresses and ports manually, but Serial Port 1 and
Serial Port 2 must have different addresses. [Disabled] prevents the serial ports from
working. Available options: [Auto] [Disabled] [3F8/COM1] [2F8/COM2] [3E8/
COM3] [2E8/COM4]
Serial Port2 Mode [Normal]
If your system already has a second serial port connected to the onboard COM2
connector and you do not want to use the infrared feature, leave on the default set-
ting [Normal]. The option [IrDA] reserves the serial port 2 for IrDA infrared com-
munications while the option [ASK IR] reserves the serial port 2 for Amplitude
Shift Keyed (ASK) infrared communications.
IR Pins / Duplex Mode / Receiver Polarity / Transmitter Polarity [N/A]
These fields are only selectable when Serial Port2 Mode is set to [IrDA] or [ASK IR].
