92 4 BIOS setup Parameter Description Option Parallel Port Mode Sets the operation mode for the parallel port. When set to Normal mode, allows normal speed one-way operation. When Bi-Directional, allows normal speed operation in a two way mode. EPP (Enhanced Parallel Port) allows bi-directional parallel port operation at maximum speed. ECP (Extended Capabilities Port) allows parallel port to operate in bi-directional mode and at a speed higher than the maximum data transfer rate. ECP Normal Bi-Directional EPP ECP Mode DMA Channel Assigns a DMA (Direct Memory Access) channel for the ECP parallel port function. This parameter is configurable only if you select ECP as the parallel port's operation mode. DMA3 DMA0 DMA1 Parallel Port IRQ Assigns an IRQ for the parallel port. If you install an add-on card that has a parallel port whose address conflicts with the onboard parallel port, a warning appears on the screen. Check the parallel port address of the add-on card and change the address to one that does not conflict. IRQ7 IRQ5

Mode
Sets the operation mode for the
parallel port.
When set to Normal mode, allows
normal speed one-way operation.
When Bi-Directional, allows normal
speed operation in a two way mode.
EPP (Enhanced Parallel Port) allows
bi-directional parallel port
operation at maximum speed. ECP
(Extended Capabilities Port) allows
parallel port to operate in
bi-directional mode and at a speed
higher than the maximum data
transfer rate.

Assigns a DMA (Direct Memory Access)
channel for the ECP parallel port
function.
This parameter is
configurable only if you select ECP as
the parallel port’s operation mode.

Parallel Port
IRQ
Assigns an IRQ for the parallel port.
If
you install an add-on card that has a
parallel port whose address conflicts
with the onboard parallel port, a
warning appears on the screen.
Check
the parallel port address of the add-on
card and change the address to one
that does not conflict.
