P5F97/P5F103 User’s Manual
Onboard FDC Controller:
The default setting is “Enabled”. This
option enables the onboard floppy disk drive controller.
Onboard Serial Port 1 and Onboard Serial Port 2:
These options
are used to assign the I/O addresses for two onboard serial ports. They
can be assigned as follows:
3F8/ IRQ4 (Serial Port 1 default)
2F8/ IRQ3 (Serial Port 2 default)
3E8/ IRQ4
2E8/ IRQ3
Auto
Disabled (Disable the onboard serial port)
UR2 Mode:
The options are “Normal” (default), “IrDA” and
“ASKIR”. The IrDA is Hewlett Packard infrared communication
protocol with maximum baud rate up to 115.2K bps, and the ASKIR
is Sharp infrared communication protocol with maximum baud rate
up to 57.6K bps. The UART mode setting depends on which type of
infrared module is used in the system. When set to “ASKIR” or
“IrDA”, the UART 2 is used to support the infrared module
connected on the mainboard. If this option is not set to “Normal”, a
device connected to the COM2 port, will no longer work.
Onboard Parallel Port:
This option is used to assign the I/O address
for the onboard parallel port. The options are “378/IRQ7” (defaults),
“278/IRQ5”, “3BC/IRQ7” and “Disabled” (disable the onboard paral-
lel port).
Parallel Port Mode:
There are four options “Normal” (default),
“EPP”, “ECP”, “ECP+EPP”. Change the mode from “Normal” to the
enhanced mode only if your peripheral device can support it.
ECP Mode Use DMA:
When set on-board parallel port to ECP
mode, the parallel port has option to use DMA “3”(default) or “1”.
On-chip USB Controller:
Set this option to “Enabled” to activate
the on-chip USB function. The default setting is “Enabled”.
USB Keyboard Support:
Set this option to “Enabled” if an
Universal Serial Bus (USB) keyboard is used in your system. The
default setting is “Disabled”.
