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 improper operation.

2-2. Installing Memory
ENDAT-7301M system board offers one 200 pin DDRII SO-DIMM socket supports
up to 1GB memory and the speed can be 400 and 533 MHz.
Note: For DIMM compatibility, please refer to page 32.
2-3. Shared VGA Memory
ENDAT-7301M is using built-in AGP VGA controller with Integrated VIA UniChrome
Pro II 3D / 2D Graphics & Video Processor up to 128MB of system memory. The
amount of video memory on motherboard determines the number of colors and the
video graphic resolution.
2-4.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.

2-5.Watchdog Timer
Watchdog Timer (WDT) is a special design for system monitoring to secure the
system work normally. WDT has an independent clock from the oscillator and could
set time and clear/refresh WDT counter function. When time is up, WDT will send
hardware RESET signal to reset system.
