IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or
multiple sector read/write. If your IDE hard drive supports block mode (most
new drives do), select Enabled for automatic detection of the optimal number
of block read/writes per sector the drive can support. The settings are:
Enabled, Disabled.
Onboard Serial Port 1
Disabled/(3F8/IRQ4)/(2F8/IRQ3)/ (3E8/IRQ4)/(2E8/IRQ3)
Onboard Serial Port 2
Disabled/(3F8/IRQ4)/(2F8/IRQ3)/(3E8/IRQ4)/(2E8/IRQ3)
The system has an On-board Super I/O chipset with 2 serial ports.
The On-board serial ports can be selected as:
Disabled
3F8/IRQ4
COM 1 uses IRQ4
2F8/IRQ3
COM 2 uses IRQ3
3E8/IRQ4
COM 3 uses IRQ4
2E8/IRQ3
COM 4 uses IRQ3
Note: Because the ISA Bus Interrupt accepts low to high edge trigger, the
interrupt request line cannot be shared by multiple sources. If an off-
board ISA add-on card with a serial port is installed the user may have
to disable the on-board serial port because it will conflict with IRQ
request line for the off-board serial port.
UART Mode Select
This item allows you to determine which InfraRed (IR) function of the
onboard I/O chip, this function uses.

Line Printer port 2
378H/IRQ5
Line Printer port 1
