Onboard Parallel Port [378H/IRQ7]
This field sets the address of the onboard parallel port connector. If you install
an I/O card with a parallel port, ensure that there is no conflict in the address
assignments. The PC can support up to three parallel ports as long as there are
no conflicts for each port. Configuration options: [Disabled] [3BCH/IRQ7]
[378H/IRQ7] [278H/IRQ5]
Parallel Port Mode [ECP+EPP]
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. This
field allows you to set the operation mode of the parallel port. The setting [Normal],
allows normal-speed operation but in one direction only; [EPP] allows bidirectional
parallel port operation at maximum speed; [ECP] allows the parallel port to operate
in bidirectional mode and at a speed faster than the maximum unidirectional data
transfer rate; [ECP+EPP] allows normal speed operation in a two-way mode. Con-
figuration options: [Normal] [EPP] [ECP] [ECP+EPP]
ECP DMA Select [3]
This field allows you to configure the parallel port DMA channel for the selected
ECP mode. This selection is available only if you select [ECP] or [ECP+EPP] in
Parallel Port Mode above. Configuration options: [1] [3] [Disabled]
