Auto Detect PCI Clk [Disabled]
Enable or Disable automatically detects PCI frequency clock.
Spread Spectrum [Disabled]
When the system clock generator pulses, the extreme values of the pulse generate excess
EMI. Enabling pulse spectrum spread modulation changes the extreme values from spikes to
flat curves, thus reducing EMI. This benefit may in some cases be outweighed by problems
with timing-critical devices, such as a clock-sensitive SCSI device. You can reduce EMI by
setting this item to turn on the clock signal with spread spectrum support.
CPU HOST/SDRAM/PCI Clock [66/100/33 MHz]
This field allows you to set the CPU and SDRAM clock frequency. The choices are: 66/66,
66/100 (Default), 70/105, 95/95, 95/126, 96/96, 97/97, 97/129, 99/99, 99/132, 100/100,
100/133, 100/150, 105/140, 110/147, 112/112, 115/153, 120/120, 133/100, 133/134,
134/134, 138/138, 140/140, 145/145, 147/147, 150/100, 160/160, and 166/110.
CPU Clock Ratio Jumpless [x 5.0]
This item allows you to set CPU Core/Bus Ratio. It would be in vain to change this item if the
CPU is locked.

Load Basic Defaults

The BASIC Defaults have been set to provide the minimum requirements for your system to
operate. Its performance is lower than the "Load Best Defaults". We suggest you use "Load
Best Default". If your system card has compatibility issues, use the "Load Basic Defaults".
4.11

Load Best Defaults

The "Load Best Defaults" function loads the system manufacture default data. This is the
default setting from Leadtek. This function will be necessary when the system CMOS data is
corrupted or you forget your settings.
4.12 Set Password
Passwords can be set to provide protection for the BIOS configuration options, or to restrict
access to the computer itself.
When enabled, User Password will require all users to enter a password in order to enter the
BIOS setup (but can't change its contents).
The password check option is set in BIOS FEATURES SETUP by choosing either System
(the password prompt appears every time the system is powered on) or Setup (the password
prompt appears only when the user enters the BIOS Setup). The password is stored in
CMOS RAM, and can be cleared by removing the battery for a while and then re-installing it
back.
