SIO
Configuration>
(continued)
Additional Information SIO:
If they exist, additional interfaces such as Serial Port 2, Serial Port 3 and Parallel Port will be
included within the SIO Configuration setup page.
The SIO Configuration menu enables all available serial interfaces to be configured. The
module-based serial interfaces always appear as COM1 and COM2. COM 1 and COM 2 can be
treated as 16550-compatible legacy COM interfaces at the standard I/O addresses and are
based in the on-module CPLD. Note: Hardware flow control is not supported.
Optionally, If the baseboard contains an activated SuperIO of the type Winbond 83627, then its
serial interfaces are added to the system as COM3 and COM4. COM3 and COM4 IRQ and I/O
addresses are configurable in this menu, too.
Although the chipset internal COMs are not supported due to technical constraints their driver
must be installed. Installing the driver does not mean that these serial interfaces are useable.
Warning: Logical Devices state on the left side of the control reflects the current logical device
state. Changes made during the setup session are shown after restarting the system.
