I/O Autodetect
The AMIBIOS detects serial and parallel ports, floppy controllers, and WD1003-compatible IDE hard disk drive controllers on
adapter cards in the system expansion slots. The Mark V Baby Screamer also has two serial ports, one parallel port, a floppy
controller, and an IDE hard disk drive controller on the motherboard.
AMIBIOS enables the onboard controllers or ports in a manner which prevents conflicts with the I/O in the expansion slots. For
example, if AMIBIOS detects a serial port on the expansion slot, it will program the two onboard serial ports as serial port2
and serial port3. If AMIBIOS cannot resolve the conflict, it generates an error message that there is a conflict. The end user
can override the autodetect feature by setting the On Board Serial Port1, On Board Serial Port 2, On Board Parallel Port, On
Board IDE, and On Board Floppy options in ADVANCED CHIPSET SETUP.
