Installation Notice
The manufacturer recommends using a grounded plug to ensure proper
motherboard operation. Care should be used in proper conjunction with a
grounded power receptacle to avoid possible electrical shock. All integrated
circuits on this motherboard are sensitive to static electricity. To avoid damaging
components from electrostatic discharge, please do not remove the board from the
anti-static packing before discharging any static electricity to your body, by
wearing a wrist-grounding strap. The manufacturer is not responsible for any
damage to the motherboard due to improperoperation.

2-2. Installing Memory
The motherboard offers two 168pin DIMM sockets supporting up to 512MB of
memory. The DIMM memory can be 66MHz or 100MHz (PC-100).
2-3. VGA S-DRAM Supporting
The ENDAT-586EL supports 4MB/8MB/16MB SDRAM. The amount of video
memory on your motherboard determines the number of colors and the video
graphic resolution.

There are two different riser cards that can be fitted to ENDAT-586EL All-In-One
motherboard. The first one is a 98pin ISA only Bus riser card (traditional ISA Bus
riser card), the second one is a 188pin PCI/ISA riser card. Please note: PCI/ISA
riser cards jumper settings have to be matched with the motherboard
AD select. The correct AD select for ENDAT-586EL All-In-One motherboard is
listed on the above table.
Caution: Do not insert PCI Bus Add-On cards directly intothe on-board
expansion slot!

13 The ENDAT-586EL All-In-One motherboard
2-5. Assigning IRQs for Expansion Cards
Some expansion cards require an IRQ (Interrupt request vector) to operate.
Generally, an IRQ must be exclusively assigned to one use. In a standard design,
there are 16 IRQ available with 11 of them already in used by other part of the
system.
Both ISA and PCI expansion cards may need to use IRQ. System IRQs are
available to cards installed in the ISA Expansion Bus first. Any remaining IRQ
then may be assigned to this PCI Bus. You can use Microsoft's Diagnostic
(MSD.EXE) utility included in the Windows directory to see their map. Make sure
that there are no two devices using the same IRQ in the system. Otherwise this will
cause the system to hang up or give 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 cards and IRQs are automatically assigned if
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 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 is automatically
assigned an IRQ to a PCI slot that has a card in it which requires an IRQ. To install
a PCI card, you need to set the correct "ADSEL" and "INT" (interrupt) assignment.
Please refer to "Chapter 2-4" Installing a Riser Card for detail assignments.

2-6. Assigning DMA Channels for ISA Cards
Since 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. In the
BIOS setup, you should choose "Yes" for those IRQ's and DMA's you wish to
reserve for Legacy cards.
