IV. BIOS SETUP
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.
The configuration options are: [Disabled] [3BCH/IRQ 7] [378H/IRQ 7] [278H/IRQ 5].
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 for-
ward (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 opera-
tion 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. The configuration options are:
[Normal] [EPP] [ECP] [ECP+EPP].
ECP DMA Select: [3]
The DMA Channel 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 the "Parallel Port Mode" above. The configuration options are: [1] [3]
[Disabled].
