All the entries on the left side of the screen are optimal settings
for this mainboard that are defined by the Auto Configuration fea-
ture, which configures the settings based on the CPU clock speed. You
should not change them.

Software Guide
Controller Settings
The default setting for "Onboard IDE Timing" is "Fast", which
supports Enhanced IDE Mode 0 to Mode 4. If the hard disk drive(s)
installed in your system do not support these timing modes, you
should change the setting to "Standard". The "Fastest" setting is not
recommended unless it fits the timing of your hard disk(s).
The default setting for the "Onboard FDC Controller" is "En-
abled" . This setting allows you to connect your floppy disk drives to
the onboard "Floppy" connector instead of a separate controller card.
Choose the "Disabled" setting if you want to use a separate control-
ler card.
The default setting for the "Onboard FDC Swap A: B:" is "No
Swap". If you want to reverse the drive letter assignments of your
floppy disk drives you can set this to "Swap AB" and the swap will
be controlled in hardware. This works separately from the BIOS Fea-
tures floppy disk swap feature .
It
is functionally the same as physi-
cally changing the floppy disk drive cable connector positions.
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
COM2
COM3
COM4
Disabled
address is 3F8H
address is 2F8H
(Onboard Serial Port 1 default)
(Onboard Serial Port 2 default)
default address is 338H
default address is 238H
turns off the on-board port
Make sure both ports have different COM assignments .
