Chapter 5 - BIOS Utility
5-27
Refer to your non-PnP ISA card manual
when setting the following parameters.
5.6.1 IRQ/DMA
This parameter allows you to assign specific IRQ and DMA channels to non-PnP
ISA cards. The system will not use such IRQ and DMA channels when it
automatically assigns channels to PnP cards.
5.6.2 Expansion ROM Region
This parameter specifies the memory regions available for add-on card use. It
allows you to manually assign specific regions to non-PnP cards so that the
system will not use those regions anymore when it automatically configures PnP
cards.
5.6.3 I/O Region
The items under this parameter allow you to reserve 16-byte memory address
ranges for non-PnP cards. When the system configures PnP cards, the address
ranges that you marked will not be used anymore.
You can assign memory addresses to non-PnP cards at random as long as you
cover the address range required by the card. For example, for a card that
requires 178h-188h address, you have to set regions 170h-17Fh and 180h-18Fh to
Yes.
5.6.4 Local Memory Region
The items under this parameter allow you to reserve areas in the local memory
region for non-PnP cards. When the system configures PnP cards, the memory
areas that you marked will not be used anymore.
