vice. This mainboard supports UltraDMA. UltraDMA technol-
ogy provides faster access to IDE devices.
If you install a device that supports UltraDMA, change the ap-
propriate item on this list to Auto. You may have to install the
UltraDMA driver supplied with this mainboard in order to use
an UltraDMA device.
Init Display First (PCI Slot)
Use this item to define if your graphics adapter is installed in
one of the PCI slots or select Onboard if you have a graphics
system integrated on the mainboard.
IDE HDD Block Mode (Enabled)
Enable this field if your IDE hard drive supports block mode.
Block mode enables BIOS to automatically detect the optimal
number of block read and writes per sector that the drive can
support and can improve the speed of access to IDE devices.
Onboard FDD Controller (Enabled)
This option enables the onboard floppy disk drive controller.
Onboard Serial Port 1/Serial Port 2 (Auto)
These options are used to assign the I/O addresses for the
two onboard serial ports.
UART 2 Mode (Standard)
This field is available if the Onboard Serial Port 2 field is set to any
option but Disabled. UART Mode Select enables you to select the in-
frared communication protocol —Standard (default), HPSIR or ASKIR.
HPSIR is Hewlett Packard’s infrared communication protocol with a
maximum baud rate up to 115.2K bps. ASKIR is Sharp’s infrared
communication protocol with a 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 HPSIR,
the UART 2 is used to support the infrared module connected
on the mainboard. If this option is not set to Standard, a de-
vice connected to the COM2 port will no longer work.
IR Function Duplex (Half)
This field is available when UART 2 Mode is set to either
ASKIR or HPSIR. This item enables you to determine the in-
frared (IR) function of the onboard infrared chip. The options
