1Hardware Installation
The American Megatrends Apollo II Pentium ISA
PCI motherboard supports:
• an Intel Pentium CPU operating at 75, 90,
100, 120, 133, 150, 166, 180, 200 MHz, or
higher speeds,
• Standard, VR, and VRE voltages.
• CPU clock speed selected through jumpers,
• optional 321-pin ZIF CPU socket,
• up to 128 MB of onboard system memory,
• PCI local bus throughput of 132 megabytes per
second,
• 256 KB or 512 KB of onboard asynchronous
SRAM direct-mapped write-back L2 cache
memory or 256 KB or 512 KB of burst SRAM
in a 160-pin IDT module,
• AMIBIOS with power management, PCI,
Flash ROM, enhanced IDE, and Plug and Play
support,
• three ISA expansion slots, and
• four PCI expansion slots.
The motherboard conforms to the PCIVersion 2.1
specification. The PCI slots are automatically
configured by the AMIBIOS. The PCI slots operate
synchronously with the CPU clock, as follows:
CPU External Clock Frequency PCI Expansion Slot Frequency
66 MHz 33 MHz
60 MHz 30 MHz
50 MHz 25 MHz
Onboard I/O The Apollo II Pentium ISA motherboard includes:
• two 40-pin IDE connectors on the PCI bus that
support up to four IDE drives,
• a 34-pin floppy drive connector,
• two 10-pin serial port connectors (with 16550
UARTs),
• a 26-pin parallel port connector with ECP and EPP
support,

Step 1 Unpack the Motherboard
Step Action
1Inspect the cardboard carton for obvious damage. If damaged,
call 770-246-8645. Leave the motherboard in its original
packing.
2Perform all unpacking and installation procedures on a ground-
connected anti-static mat. Wear an anti-static wristband
grounded at the same point as the anti-static mat. Or use a
sheet of conductive aluminum foil grounded through a 1
megohm resistor instead of the anti-static mat. Similarly, a
strip of conductive aluminum foil wrapped around the wrist
and grounded through a 1 megohm resistor serves the same
purpose as the wristband.
3Inside the carton, the motherboard is packed in an anti-static
bag, and sandwiched between sheets of sponge. Remove the
sponge and the anti-static bag. Place the motherboard on a
grounded anti-static surface component side up. Save the
original packing material.
4Inspect the motherboard for damage. Press down on all ICs
mounted in sockets to verify proper seating. Do not apply
power to the motherboard if it has been damaged.
5If the motherboard is undamaged, it is ready to be installed.
Set Jumpers Set all jumpers and install the CPU before placing
the motherboard in the chassis.
Avoid Static Electricity
Static electricity can damage the motherboard and
other computer components. Keep the motherboard
in the anti-static bag until it is to be installed.
Wear an anti-static wrist grounding strap before
handling the motherboard. Make sure you stand on
an anti-static mat when handling the motherboard.
Avoid contact with any component or connector on
any adapter card, printed circuit board, or memory
module. Handle these components by the mounting
bracket.
