(maximum) with DRAM Table Free configurations;
2. Supports Fast Page Mode/EDO/Synchronous DRAM
with 60ns/70ns DRAM speed;
3. Supports 4 pcs 72pin SIMM sockets and 2 pcs 168pin
DIMM sockets (3.3V unbuffered type).

2
BIOS
1. AWARD Plug and Play BIOS;
2. Supports Advanced Power Management Function;
3. Flash Memory for easy upgrade.
I/O Function
1. Integrated USB (Universal Serial Bus) controller with
two USB ports;

2. 4 PCI Master slots and 4 ISA slots;
3. Supports SCSI/CD-ROM Boot function;
4. DIP Switch setting, simplied the setting procedure.
Note: 1. Make sure that the SDRAM module not only has to be
168 pin DIMM but designed for 3.3V unbuffered
SDRAM as well. Double check with the SDRAM
supplier before install any SDRAMs. The mainboard
manufacturer has no obligation to any damage of the
board by using the incorrect specification of SDRAM.
2. Pentium MMX (P55C), Cyrix 6x86L/6x86MX (M2),
and AMD K6 are dual voltage CPUs. JP1/JP2 must
be set correctly (refer to page 4). Check with your
CPU supplier for the CPU voltage specification.

Introduction 3
Mainboard Setting for Pentium MMX-166
The default setting of the following figure is for the INTEL
Pentium MMX-166 with the 256K (or 512K) cache. To get
the best cooling effect, make sure that the airflow from the
CPU fan is facing the heatsink.

Note: 1. Refer to the table above to choose the correct voltage
for the CPU everytime that you install a CPU.
2. CPU VI/O is fixed on 3.3V.
3. Make sure that your JP1 and JP2 are matched with
the CPU voltage, otherwise will damage the CPU or
make the system unstable.
4. When the new CPU is announced and is not listed
on this manual, please refer to the above table, select
the correct voltage setting for it.
JP1: Single/Dual Voltage Select Jumper
JP1 is an jumper to use to select either single or dual CPU
voltage. This jumper is designed to use with JP2 together in
order to set the correct CPU voltage. Incorrect
combinations may cause the system unstable or damage
the CPU.

System Memory Configuration
This Apollo VP motherboard supports 72-pin SIMMs and
168pin DIMMs (3.3V unbuffered type) of 4MB, 8MB, 16MB,
or 32MB to form a memory size between 4MB to 512MB
(total of 6 rows are supported).
The Apollo VP chipset supports ÒTable FreeÓ configuration
so that DRAM module can be installed at any capacity
except SIMM3, 4 and DIMM2 canÕt be installed at the same
time.
