BIOS will automatically load Ultra DMA 33 driver to match the
transfer rate of IDE hard disk drive which supports Ultra DMA 33
mode. The default setting is “Auto”.
On-Chip Primary/Secondary PCI IDE: The default setting is
“Enabled”. This option enables the onboard Primary / Secondary PCI
IDE controller.
USB Keyboard Support: Set this option to “Enabled” if an
Universal Serial Bus (USB) keyboard is used in your system. The
default setting is “Disable”.
Init Display First: This feature allows user to set the first initial
display device. For example, when set to “AGP” then AGP will be
the master and first initial display device. The options are “AGP”
(default) and “PCI slot”.
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)
2F8/ IRQ3 (Serial Port 2)
3E8/ IRQ4
2E8/ IRQ3
Auto (default setting for serial port 1 and 2)
Disabled (Disable the onboard serial port)
UART 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.
