3.1 Processor
The MI7WBM motherboard is designed to take an Intel Celeron
processor running 300/333/350/366/400/433/450/466/500MHz.
3.2 L2 Cache
The L2 cache is integrated in the processor.
3.3 Main Memory
The MI7WBM motherboard supports two 168-pin DIMM (Dual In-line
MemoryModule) sockets to forma memory configuration from 64MB to
256MB. DIMM modules can be 64M and128MB in SDRAM. In
populating the DIMM sockets, any socket can be populated first. Refer to
the following table on how to do the memory configuration.
(DIMM1) (DIMM2) Total Memory
64MB ----- 64MB
128MB ----- 128MB

3.4 BIOS
The BIOS on the MI7WBM motherboard provides the standard BIOS
functions plus the following feature:
Power Management
The power management feature provides power savings by slowing
down the CPU clock, turning off the monitor screen and stopping the
HDD spindle motor. The BIOS fully conforms to ACPI (Advanced
Configuration and Power Interface) specification.
3.5 Onboard VGA
The highly integrated graphics accelerator consists of dedicated

Chapter 4 Configuring the Motherboard
MI7WBM User’s Manual 13
4.1 CPU Frequency Setting
The MI7WBM uses jumper-free technology in configuring the processor
on the motherboard. The system automatically detects the CPU bus
speed, 66MHz or 100MHz and sets the multiplier, or ratio, to 3X.
However, the bus speed can also be configured through the BIOS if the
processor supports this feature. The BIOS (under CPU Features Setup)
allows users to change the CPU bus speed multiplier (3X, 3.5X, 4X,
4.5X, 5X, 5.5X, 6X, 6.5X, 7X, 7.5X, 8X) to set the correct or desired
CPU frequency. The CPU bus speed multiplier will remain unchanged if
the CPU installed supports a fixed (only one) bus speed multiplier.
It is possible that the system will not boot if the CPU has been
changed. When this happens, turn off the computer by pressing
the power button and turn it on again by pressing the Insert key
and the power button simultaneously. (Note to press the Insert
key until an image appears on the screen.) When the system is
turned on, press the Delete key to enter BIOS Setup and
configure the CPU speed.
4.2 JP9: 100MHz CPU Host Frequency Force Selector
The MI7WBM is able to detect the host frequency (66MHz or 100MHz)
of the installed CPU. The JP9 jumper, however, can be set to OPEN to
override the detection and force the host frequency to run at 100MHz.

4.7 JP17: Memory Clock Select
For MI7WBM Series Ver. 1.00
The MI7WBM comes with the JP17 memory clock select jumper. In case
you are using 64MB NEC or LGS SDRAM module and the system does
not boot, set JP17 to SHORT to delay the memory clock.
For MI7WBM Series Ver. 1.20
1.When only one DIMM slot is used, leave JP17 OPEN
2.When 2 DIMM slots are used, set JP17 to SHORT.
3.When using NEC DIMM modules, regardless one or two DIMM slots
are used, JP17 should be set to SHORT.
4.When using CPU bus speed of 66MHz, leave JP17 OPEN.
IMPORTANT NOTES:
1. If the memory module you are using is not included in our test report
or is an ‘unknown’ brand, set JP17 to OPEN first. (It is recommended to
use PC-100 compatible memory modules.) If the system does not boot,
then set JP17 to short.
2. Regardlessof the brand of memory module you are using, they must be
PC-100 compatible modules.
3. In the BIOS setup on page 40, there is an option for the SDRAM cycle
time. Its setting must meet the specification of your SDRAM module. Or
else, the system might become unstable.
4. If your CPU uses 100MHz bus speed, JP17 should be SHORT.
4.8 JP19: CPU Select
The JP19 2-pin jumper is used in conjunction with the processor installed
on the motherboard. When the processor is an Intel Coppermine/Celeron
processor with 128K cache, JP19 should be OPEN. For an Intel
Coppermine processor with 256K cache, JP19 should be
CLOSED/SHORT.

4.9 JP22, JP23: Celeron / Coppermine Select
The default setting of the JP22 and JP23 2-pin jumpers are SHORT,
which setting is used for Intel Coppermine and Intel Celeron CPUs.
However, for Intel Celeron processors with CPU ID 066X, JP22 and
JP23 should be left OPEN.
The JP22 and JP23 jumpers can be found only in MI7WBM Series
Ver. 1.20.

The 5VSB LED light is on to indicate that there is suspend power signal
fromthe power supply. The VCCLED light is onto indicate the power is
