Onboard Parallel Port: [378H/IRQ7]

This field allows you to configure the Notebook PC parallel port. The configuration options are: [Dis-

abled] [378H/IRQ7] [278H/IRQ5]

Parallel Port Mode: [ECP]

The Mode field allows you to configure the Notebook PC parallel port transmission mode. The

configuration options are: [Normal] [Bi-dir] [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.
