Hardware Installation
2-1 Unpacking
This mainboard package should contain the following:
The J-542B/J-542BS mainboard
USER’S MANUAL for mainboard
Cable set for IDE x1, Floppy x1, COM Port x1, Printer port x1,
Audio+Game-1 x1 (Only in J-542BS)
CD for Drivers PACK
The mainboard contains sensitive electronic components which can be easily damaged
by electron-static, so the mainboard should be left in its original packing until it is
installed.
Unpacking and installation should be done on a grounded anti-static mat.
The operator should be wearing an anti static wristband, grounded at the same point as
the anti-static mat.
Inspect the mainboard carton for obvious damage. Shipping and handling may cause
damage to your board. Be sure there are no shipping and handling damages on the
board before proceeding.
After opening the mainboard carton, extract the system board and place it only on a
grounded anti-static surface component side up. Again inspect the board for damage.
Press down on all of the socket IC’s to make sure that they are properly inserted. Do
this only on with the board placed on a firm flat surface.
Warning: Do not apply power to the board if it has been damaged.
You are now ready to install your mainboard. The mounting hole pattern on the
mainboard matches the IBM-AT system board.
It is assumed that the chassis is designed for a standard IBM XT/AT main board
mounting. Place the chassis on the anti-static mat and remove the cover.
Take the plastic clips, Nylon stand-off and screws for mounting the system board, and
keep them separate.

2-7 Central Processing Unit (CPU)
The motherboard provides a 321-pins ZIF Socket 7. The CPU on mother board must
have a fan attached to prevent overheating.

Page 12
W
WARNING: Without a fan, the CPU will overheat and cause damage to both the CPU and
the motherboard.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket
and open it by first pulling the lever sideways away from the socket then upwards to a
90-degree right angle. Insert the CPU with the white dot as your guide. The white dot
should point towards the end of the level. The CPU has a corner pin for three of the
four corners, the CPU will only fit in the one orientation as shown as follow. With the
added weight of the CPU fan, no force is required to insert the CPU. Once completely
inserted, hold down on the fan and close the socket’s lever.
IMPORTANT: You must set jumper SW1 “DIP Switch for CPU Type Selection” and jumper JP3
“CPU Voltage Selection” on page 7 depending on the CPU that you install.

2-8 Expansion Cards
First read your expansion card documentation on any hardware and software settings
that may be required to setup your specific card.
Installation Procedure:
1. Read the documentation for your expansion card.
2. Set any necessary jumpers on your expansion card.
3. Remove your computer’s cover.
4. Remove the bracket on the slot you intend to use.
5. Carefully align the card’s connectors and press firmly.
6. Secure the card on the slot with the screw you remove in step 4.
7. Replace the computer’s cover.
8. Setup the BIOS if necessary.
9. Install the necessary software drivers for your expansion card.
Assigning IRQs for Expansion Cards
Some expansion cards may require an IRQ to operate. Generally an IRQ must be
exclusively assigned to only one device. In an standard design there are 16 IRQs
10
Page 13
available but most of them are occupied by the system and leaves 6 free for expansion
cards.
Either ISA or PCI expansion cards may require an IRQs. System IRQs are available to
cards installed in the ISA expansion first, and any remaining IRQs can be used by PCI
cards. Currently, there are two types of ISA cards. An original ISA expansion card
design, know as “Legacy” ISA cards, they request configure the card’s jumpers
manually and then install it in any available slot on the ISA bus, and other know as Plug
and Play. You may use Microsoft’s Diagnostic (MSD.EXE) utility included in the DOS
directory to see a map of your used and any free IRQs. For Windows 95 users, the
“Control Panel” icon in “My Computer”, contains a “System” icon which gives you
“Device Manager” tab. Double clicking on a specific device give you “Resources” tab
which shows the Interrupt number and address. Make sure that no any two of devices
use the same IRQs, or your computer will experience problems when those two devices
are in use at the same time.
To simplify this process the motherboard has complied with the Plug and Play (PNP)
specification which was developed to allow automatic system configuration whenever a
PNP-compliant card is added to the system. For PNP cards, 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 a utomat ically a ssigns an
IRQ to a PCI. 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 INT A.
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. In the BIOS setup, you
should choose “Yes” for those IRQ’s and DMA’s you wish to reserve for Legacy cards.
2-9 External Connectors
1. Power connector: AT Power Connector (12-pin block): J3
This connector connects to a standard 5 Volt power supply. To connect the leads
from the power supply, ensure first that the power supply is not plugged. Most

)
power supplies provide two plugs (P8 and P9), each containing six wires, two of
which are black. Orient the connectors so that the black wires are located in the
middle.
Using a slight angle, align the plastic guide pins on the lead to their receptacles on the
connector. Once aligned, press the lead onto the connector until the lead locks into
place.

jumper pole on the motherboard. When the power switch on the back of the ATX
power supply turned on, the full power will not come into the system board until the
front panel switch is momentarily pressed. Press this switch again will turn off the
power to the system board.
