NEX732L2G User Manual

Onboard LAN (1 & 2) Boot ROM

Decide whether to invoke the boot ROM of the onboard LAN chip. The available choices are LAN1, LAN2,

and Disabled.

Onboard FDC Controller

Select Enabled if your system has a floppy disk controller (FDC) installed on the system board and you

wish to use it. If you install an add-in FDC or the system has no floppy drive, select Disabled in this field.

Onboard Serial Ports (1, 2)

Select an address and corresponding interrupt for the first and second serial ports.

The choices: Auto, 3F8/IRQ4, 3E8/IRQ4, 2F8/IRQ3, 2E8/IRQ3, Disabled.

UART Mode Select

This item allows you to select UART mode. The choices: Normal, IrDA, ASKIR.

RXD, TXD Active

Choices for RXD, TXD Active include Hi, Hi; Hi, Lo; Lo, Hi; and Lo, Lo.

IR Transmission Delay

Select Enabled for IR transmission delay.

UR2 Duplex Mode

In an infrared port mode, this field appears. Full-duplex mode permits simultaneous two-direction transmission.

Half-duplex mode permits transmission in one direction only at a time. Select the value required by the IR

device connected to the IR port.

Use IR Pins

There are two choices -- RXD2, TXD2 and IR-RX2TX2 -- available for use of the IR Pins.

Onboard Serial Ports (3, 4)

This feature allows you to manually select the I/O address and IRQ for the first and second serial ports. It is

recommended that you leave it as Auto so that the BIOS can select the best settings for it. But if you need

a particular I/O port or IRQ that's been taken up by this serial port, you can manually select an alternative I/

O port or IRQ for it. You can also disable this serial port if you do not need to use it. Doing so frees up the

I/O port and IRQ used by this serial port. Those resources can then be reallocated for other devices to use.

Onboard Parallel Port

This feature allows you to manually select the I/O address and IRQ for the onboard parallel port. The default

I/O address of 378h and IRQ of 7 should work well in most cases. Unless you have a problem with the

parallel port, you should leave it at the default settings. The choices: 378/IRQ7, 278/IRQ5, 3BC/IRQ7, and

Disabled.
