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: [278H/IRQ
5] [Disabled] [3BCH/IRQ 7] [378H/IRQ 7]
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 re-
quired. 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 op-
eration mode of the parallel port. The setting [Normal], allows normal-
speed operation but in one direction only; [EPP] allows bidirectional par-
allel port operation at maximum speed; [ECP] allows the parallel port to
operate in bidirectional mode and at a speed faster than the maximum uni-
directional data transfer rate; [ECP+EPP] allows normal speed operation
in a two-way mode. Configuration 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]
