Init Display First
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
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
This option enables the onboard floppy disk drive controller.
Onboard Serial Port 1/Serial Port 2
These options are used to assign the I/O addresses for the two onboard
serial ports.
UART 2 Mode
This field is available if the Onboard Serial Port 2 field is set to any op-
tion but Disabled. UART Mode Select enables you to select the infrared
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 op-
tion is not set to Standard, a device connected to the COM2 port will no
longer work.
IR Function Duplex
This field is available when UART 2 Mode is set to either ASKIR or
HPSIR. This item enables you to determine the infrared (IR) function of
the onboard infrared chip. The options are Full and Half (default).
Full-duplex means that you can transmit and send information simulta-
neously. Half-duplex is the transmission of data in both directions, but
only one direction at a time.
