5. BIOS Setup

Base I/O address: [2F8 IRQ 3]

This field allows you to configure the Notebook PC’s serial IR port. The configuration options are:
[3F8, IRQ 4] [2F8, IRQ 3] [3E8, IRQ 4] [2E8, IRQ 10] [Disabled]

Mode: [FIR]

This field allows you to select either Standard Infrared (SIR) or Fast Infrared (FIR) communication
mode. The configuration options are: [IrDA SIR] [FIR]

DMA channel: [DMA 3]

The DMA Channel field allows you to configure the Parallel port DMA Channel for the selected
ECP mode. NOTE: This field is only available when the Parallel port field is set to User and the
Mode field is set to ECP. The configuration options are: [DMA 1] [DMA 3]

Parallel port: [User]

This field allows you to configure the Notebook PC parallel port. The configuration options are:
[Disabled] [User] [Auto]

Mode: [EPP]

The Mode field allows you to configure the Notebook PC parallel port transmission mode. The
configuration options are: [Output Only] [Bi-directional] [ECP] [EPP]

EPP Mode: When the EPP mode is selected, the standard and bidirectional modes are also avail-
able. The EPP operates on a two phase cycle. First, the host selects the register within a device for
subsequent operations. Second, the host performs a series of read and/or write byte operations to the
selected register. There are four operations supported by EPP: Address Write, Data Write, Address
Read, and Data Read. All operations are performed asynchronously.

ECP Mode: The port is both software and hardware compatible with existing parallel ports so that
it may be used as a standard printer mode if ECP is not required. ECP mode provides an automatic
high burst-bandwidth channel that supports DMA for ECP in both the forward (host to peripheral)
and reverse (peripheral to host) direction.

The Output only mode allows data output only. However, EPP and ECP are Bidirectional modes,
allowing both data input and output. The EPP and ECP modes are only supported with EPP and
ECP aware peripherals.

Base I/O address: [378H/IRQ7]

This field allows you to configure the Notebook PC parallel port. The configuration options are:
[Disabled] [3BCH/IRQ7] [378H/IRQ7] [278H/IRQ5]

NOTE: After using the legend keys to make your selections for the I/O Device Configuration sub-
menu, press the [Esc] key to exit back to the Advanced menu.
