4. Using the Notebook PC
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]
Mode: [ECP]
The Mode field allows you to configure the Notebook PC parallel port transmission mode. The
configuration options are: [Normal] [EPP] [ECP]
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.
ECP DMA Select: [3]
This field allows you to configure the Parallel port DMA channel for the selected ECP mode. The
configuration options are: [1] [3]
NOTE: After using the legend keys to make your selections for the I/O Device Con-
figuration sub-menu, press the [Esc] key to exit back to the Advanced menu.
