Parallel Port
This parameter allows you to enable or disable the parallel port.
BASE ADDRESS
This function lets you set a logical base address for the parallel port.
The options are:
• 3BCh
• 378h
• 278h
IRQ
This function lets you assign an interrupt for the parallel port. The
options are IRQ 5 and 7.
The Base Address and IRQ parameters are
configurable only if Parallel Port is enabled.
If you install an add-on card that has a
parallel port whose address conflicts with the
parallel port onboard, the system
automatically disables the onboard functions.
Check the parallel port address on the add-
on card and change the address to one that
does not conflict.
