system. For PnP cards, IRQs are assigned automatically from those
currently available.
If the system has both Legacy and PnP ISA card installed, IRQs are
assigned to PnP cards from those not used by Legacy cards. The
PCI
and PnP Configuration
section of the BIOS setup utility can be used
to indicate which IRQs are being used by Legacy cards. For older
Legacy cards that do not work with the BIOS, you can contact your
vendor for an ISA configuration utility. An IRQ number is
automatically assigned to PCI expansion cards after those used by
Legacy and PnP ISA cards. In the PCI bus design, the BIOS
automatically assigns an IRQ to any PCI slot which has a card that
requires an IRQ. To install a PCI card, you need to set something
called the INT (interrupt) assignment. Since all the PCI slots on this
motherboard use an INTA#, be sure that the jumpers on your PCI
cards are set to INTA.
2.4.2.1 Assigning DMA Channels for ISA Cards
Some ISA cards, both Legacy and PnP may also need to use a DMA
(Direct Memory Access) channel. DMA assignments for this
motherboard are handled the same way as the IRQ assignment process
described above. You can select a DMA channel in the PCI and PnP
configuration section of the BIOS Setup utility.
NOTE:
Choose "Yes" for those IRQ's and DMA's you wish to
reserve for Legacy (Non-PnP) ISA expansion cards in "IRQ xx Used
by ISA" and "DMA x Used By ISA" under
PnP and PCI Setup
in the
BIOS Setup, otherwise conflicts may occur.
