22 The ENDAT-9401F/H System Board
2-3. Installing Memory
ENDAT-9401F/H system board offers one 240pin DDR-2 SDRAM socket supports
up to 2GB memory and the speed can be 533 / 667 MHz.
2-4. Shared VGA Memory
ENDAT-9401F/H is using built-in INTEL® GMA950 Graphic with INTEL DVMT 3.0
up to 224MB of system memory. The amount of video memory on motherboard
determines the number of colors and the video graphic resolution.
2-5. Assigning IRQs for Expansion Cards
Some expansion cards require an IRQ (Interrupt request vector) to operate.
Generally, each IRQ must be exclusively assigned to specific use. In a standard
design, there are 16 IRQ available with 11 of them already in used by other part of
the system.
Some PCI expansion cards need IRQ; any remaining IRQ could be assigned to PCI
Bus. Microsoft’s Diagnostic (MSD.EXE) utility included in the Windows directory
can be used to see their map. Clients can not have more than one device apply the
same IRQ in the system or it will cause the system hang up, crash, and unexpected
results. To simplify the process, this motherboard complies with the Plug and Play
(PnP) specifications, which was developed to allow automatic system configuration.
Whenever a PnP-compliant card is added to the system, PnP card and IRQs will
automatically assigned if available. The PCI and PnP configuration in the BIOS
setup utility can indicate which IRQs have being used by Legacy cards.
In the PCI Bus design, the BIOS is automatically assigned an IRQ to a PCI slot that
has a card in it which requires an IRQ. To install PCI cards via riser card, you need
to set the correct “ADSEL” and “INT” (interrupt) assignment on the jumper of riser
card.
