Be sure to unplug the AC power supply before adding or removing
expansion cards or other system peripherals, especially the DDR
memory, otherwise your motherboard or the system memory might
be seriously damaged.
Be sure to add some Silicone Grease between the CPU and the AN
to keep them fully contact, meanwhile to meet the heat sink
requirement.

Introduction
Overview
The KuDoz 7E/333 series are high performance, cost-effective and energy efficient
motherboards from 200MHz and 266MHz FSB based on Socket-A processors. They
utilize the Apollo KT 266A chipset consisting of VIA KT333 and VT8233A. They support
the UltraDMA-33/66/100/133, DDR SDRAM and AGP 4x. They also provide one ACR
slot and one SCR(Smart Card Reader) interface connector. In addition, advanced fea-
tures are supported such as wake-up on LAN, wake-up on internal/external modem,
wake-up by hot keys of PS/2 keyboard, ACPI power management and hardware monitor-
ing.
IMPORTANT: Onboard Audio( AC97 codec ) and Onboard SoundBlaster( Creative®
CT 880 ) are optional. Please take note of the difference.

Installation Instruction
ATX Power Supply Connector & Power Switch (POWER SW)
Be sure to connect the power supply plug to this connector in its proper orientation. The
power switch ( POWER SW ) should be connected to a momentary switch (power button).
When powering up your system, first turn on the mechanical switch of the power supply
( if one is provided ), then push once the power button. When powering off the system,
you neednt turn off the mechanical switch, just Push once* the power button.
Note: * If you change soft-off by PWRBTN from default Instant-off to Delay 4
Sec in the POWER MANAGEMENT SETUP section of the BIOS, the power button
should be pressed for more than 4 seconds before the system powers down.

UART Mode Select to IrDA or ASKIR and configure the settings in the INTEGRATED
PERIPHERALS section of the BIOS.
Wake-Up On LAN (WOL)
Through the Wake-Up On LAN function, a wake event occurring from the network can
wake up the system. If this function is to be used, please be sure an ATX 2.01 power supply
of which VSB line is capable of delivering 720mA, and a LAN adapter which supports this
function is used. Then connect this header to the relevant connector on the LAN adapter,
set Wake up on LAN/Ring as Enabled in the POWER MANAGEMENT SETUP section of
the BIOS. Save & exit, then boot the operating system once to make sure this function takes

Wake-Up On Internal Modem (WOM)
Through the Wake-Up On Internal Modem function, the system which is in the suspend or
soft-off status can be waked up by a ring signal received from internal modem. If this
function is to be used, be sure an internal modem card which supports the function is used.
Then connect this header to the relevant connector on the modem card, set Wake up on
LAN/Ring  as Enabled in the POWER MANAGEMENT SETUP section of the BIOS. Save &
exit, then boot the operating system once to make sure this function takes effect.
Internal Audio Connectors (AUX, CD_IN, MODEM)
(Available on KuDoz 7E/333-A/-C)
AUX and CD_IN connectors allow you to receive audio input from such sound sources
as a CDROM, TV tuner, or MPEG card. The MODEM connector allows the onboard
audio to interface with a voice modem card with a similar connector. It allows connecting
the mono_in (such as a phone) or mono_out (such as a speaker) between the onboard
audio and the voice modem card.

Advanced Communications Riser Slot (ACR)
The ACR connector uses a standard connector that is reversed and offset. Legacy AMR
card can be plugged into the ACR slot and works without modification. ACR provides a
common architecture for analog modem. It supports legacy AMR riser designs for modem
and audio codecs.
Note:
For the KuDoz 7E/ , the AMR card should be set as AMR Primary card to use
only.
For the KuDoz 7E/ -A, to avoid conflict, you should set the AMR card as Slave
when use onboard audio codec( AC97 Codec ) or set the AMR card as Primary
and jumpers JP1, JP2, JP as disabling onboard audio codec( AC97 Codec ) when
use the audio codec on the AMR card.
For the KuDoz 7E/ -C, the PCI1 slot can only use Slave card, and the AMR
card should be set as AMR Primary card to use only.
Smart Card Reader Connector(SCR)
The SCR interface connector is the interface between the motherboard and the Smart
Card.
The SCR is built in IT870 F I/O chip and includes a standard UART to control Smart Card
interface handshaking and then performs data transfers. The SCR can be used for a
broad range of applications in GSM, ID, pay TV, banking and so forth. It also provides a
Smart Card clock divider for those ICC ( Integrated Circuit Card ) without internal clocks. If
use this function, set UART Mode Select to SCR in the INTEGRATED PERIPHERALS
section of the BIOS and jumpers J , J6 as SCR enabled.

Jumpers are located on the motherboard, they represent, clear CMOS jumper JCC,
enable BIOS ProtectEasy function jumper JAV etc. Pin 1 of all jumpers are located on
the side with a thick white line ( Pin1→ ), refer to the motherboards
silkscreen. Jumpers with three pins will be shown as to represent pin1 & pin2
connected and to represent pin2 & pin3 connected.
Overclocking Jumper Setting (J SB)
The jumper JFSB located on the mainboard provides users with CPU overclocking feature.
The host bus speed can be set as 100/133MHz. The table below for your reference.
AMD Athlon CPU FSB is 100MHz/133MHz, but delivering twice the throughput of 100MHz/
133MHz Pentium III-based systems(Ultra -Fast 200MHz/266MHz). However, whether or
not your system can be overclocked depends on your processors capability. We do not
guarantee the overclocking system to be stable.
Warning: Be sure your selection is right. CPU over speed will be dangerous! We will
not be responsible for any damages caused.
Note: t is not used with FSB 133 CPU and FSB 100 DDR together.

CPU Bus Ratio Setting (J1, J3)
The Host Bus speed by the CPU bus ratio equals the CPUs internal frequency (CPU speed)
If Host Bus speed = 100MHz, CPU bus ratio =4
then CPU speed= 100MHz x 4= 400MHz
please set CPU bus ratio according to the following table.
Note: The most of Socket-A processors have bus ratio locked. In this case, its
not necessary to set the bus ratio by jumper setting. So only unlocked Socket- A
processors can adjust specified bus ratio through hardware jumper setting.
Warning: Be sure your selection is right. CPU over speed will be dangerous! We
will not be responsible for any damages caused.
