2-1 Hardware installation Steps
Before using your computer, you had better complete the following steps:
1. Check motherboard setting
2. Install CPU
3. Install Memory
4. Install Expansion cards
5. Connect Ribbon cables, Panel wires, and power supply
6. Setup BIOS
7. Install software driver & utility
2-2 Checking Motherboard’s Jumper Setting
1. CPU Host/SDRAM Clock setting (3-pin) : JS4, JS1, JS2, JS3
The motherboard’s CPU & SDRAM memory clock adjusted through jumper JS4, JS1,
JS2 & JS3. Table as below:

∗
When jumper setting Auto it only can support CPU/SDRAM frequency at 66/100,
100/100, 133/100 MHz, we recommend setting 133/133 by manual adjust when use
F.S.B. 133MHz CPU to increase performance, and it will more stable, especially when
use Cyrix III F.S.B. 133 MHz CPU.
In “Miscellaneous Control” section of CMOS setup Utility, you can setting the CPU
clock step by step increase please refer
page 13
.
2. Keyboard Power On Function setting (3-pin) : JK1
This allows you to disable the keyboard power on function. Set the jumper to enabled
or disabled if you wish to use your keyboard (by pressing < >) to power on your
computer, this feature requires an ATX power supply that can supply at least 300mA on
the +5VSB lead. The default is set on disable.
