Installation
Both ISA and PCI expansion cards may need to use IRQs. System IRQs are
available to cards installed in the ISA expansion bus first, and PCI cards
then use any remaining IRQs. Currently, there are two types of ISA cards.
The original ISA expansion card design, now refe rred to as " Legacy " ISA
cards, requires that you configure the card's jumpers manually and then
install it in any available slot on the ISA bus. You may use Microsoft's
Diagnostic (MSD.EXE) utility included in the Windows directory to see a map
of you’re used and free IRQs. For Windows 95 users, the "Control Panel"
icon in " My computer" contains a "System" icon which give you a "Device
Manager" tab. Double clicking on a specific device give you "Re sources" tab
which shows the Interrupt number and addres s. Make sure that no two
devices use the same IRQs or your computer will experience problems
when those two devices are in use at same time.
To simplify this process this Single-board Computer has complied with the
Plug and Play specification, which was, developed to allow automatic
system configuration whenever a PNP Compliant card is added to the
system. For PNP card, IRQs are assigned automatically from those
available.
If the System has both Legacy and PNP ISA Cards installed, IRQs are
assigned to PNP cards from those not used by Legacy cards. The PCI and
PNP configuration of the BIOS setup utility can be used to indicate which
IRQs are being used by Legacy cards. For older Legacy cards that does 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
AUTO assigns an IRQ to PCI slot that has a card in it 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 the NUPRO-710 use an INTA#, be
sure that the jumpers on your PCI cards are set to INTA.
Assigning DMA Channels for ISA Cards
Some ISA cards, both Legacy and PNP may also need to use a DMA channel.
DMA assignments for the NUPRO-710 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.
IMPORTANT:
In BIOS setup, you should choose “YES” for those IRQ’s and
DMA’s you wish to reserve for Legacy (Non-PNP) ISA cards,
otherwise conflicts may occur.
