Controller Settings
The default setting for the "Onboard FDC Controller" is "En
abled". This setting activates the onboard floppy disk controller and
connector. Choose the "Disabled" setting if you want to use a sepa
rate controller card.
The default setting for the "Onboard FDC Swap A: B:" is "No
Swap". If you want to reverse the drive letter assignments of two
floppy disk drives you can set this to "Swap AB" and the swap will
be controlled in hardware. This feature is the same as physically
changing the floppy disk drive cable connector positions. It is sepa
rate from the BIOS Features Setup "Swap Floppy Drive" feature.
Serial Ports
The "Onboard Serial Port 1" and "Onboard Serial Port 2" lines
control the assignments for the mainboard's two onboard serial con
nectors. They can be assigned as follows:
COMl address is 3F8H (Onboard Serial Port 1 default)
COM2 address is 2F8Fi (Onboard Serial Port 2 default)
COM3 default address is 3E8H
COM4 default address is 2E8H
Disabled turns off the on-board port
Make sure both ports have different COM assignments. It should
be unnecessary to change the default settings.
