IRQ for the onboard parallel port.

Parallel Port Mode
The options are SPP, EPP, ECP and ECP+EPP. These apply to a
standard specification and will depend on the type and speed of
your device. Refer to your peripheral’s manual for the best option.
SPP
Allows normal speed operation but in one direction only.
ECP (Extended Capabilities Port)
Allows parallel port to operate in bidirectional mode and at a
speed faster than the normal mode’s data transfer rate.
EPP (Enhanced Parallel Port)
Allows bidirectional parallel port operation at maximum speed.
If you selected EPP, the “EPP Mode Select” field is configurable. If
you selected ECP, the “ECP Mode Use DMA” field is configurable. If
you selected ECP+EPP, both “EPP Mode Select” and “ECP Mode
Use DMA” are configurable.
ECP Mode Use DMA
This is used to select the DMA channel of the parallel port.

AGP

AGP.
PCI Slot
