Conflicts
AMIBIOS minimize conflicts between onboard and offboard I/O devices.
AMIBIOS automatically checks the adapter cards installed in the expansion
slots on the Titan III PCI EISA motherboard for a hard disk or floppy
controller and serial or parallel ports.
P3, P4
P3 (serial port1) and P4 (serial port 2) are 10-pin connectors that provide an
AT-compatible serial port interface. Connect the cables supplied with the
motherboard to P3 and P4. The serial port base I/O port address and other
serial port settings can be selected in Peripheral Setup in WINBIOS Setup.
The P3 and P4 pinout is shown below.
