WEEE (Waste Electrical and Electronic Equipment) Statement

ENGLISH

To protect the global environment and as an environmentalist, BCM must re­mind you that:

Under the European Union (“EU”) Directive on Waste Electrical and Electronic
Equipment, Directive 2002/96/EC, which takes effect on August 13, 2005,
products of “electrical and electronic equipment” cannot be discarded as municipal waste
anymore and manufacturers of covered electronic equipment will be obligated to take back
such products at the end of their useful life. BCM will comply with the product take back
requirements at the end of life of BCM-branded products that are sold into the EU. You can
return these products to local collection points.

DEUTSCH

Hinweis von BCM zur Erhaltung und Schutz unserer Umwelt
Gemäß der Richtlinie 2002/96/EG über Elektro- und Elektronik-Altgeräte dürfen Elektro-

und Elektronik-Altgeräte nicht mehr als kommunale Abfälle entsorgt werden. BCM hat
europaweit verschiedene Sammel- und Recyclingunternehmen beauftragt, die in die Eu­ropäische Union in Verkehr gebrachten Produkte, am Ende seines Lebenszyklus zurück­zunehmen. Bitte entsorgen Sie dieses Produkt zum gegebenen Zeitpunkt ausschliesslich
an einer lokalen Altgerätesammelstelle in Ihrer Nähe.

FRANÇAIS

En tant qu’écologiste et afi n de protéger l’environnement, BCM tient à rappeler ceci:
Au sujet de la directive européenne (EU) relative aux déchets des équipement électriques

et électroniques, directive 2002/96/EC, prenant effet le 13 août 2005, que les produits
électriques et électroniques ne peuvent être déposés dans les décharges ou tout simple­ment mis à la poubelle. Les fabricants de ces équipements seront obligés de récupérer
certains produits en fi n de vie. BCM prendra en compte cette exigence relative au retour
des produits en fi n de vie au sein de la communauté européenne. Par conséquent vous
pouvez retourner localement ces matériels dans les points de collecte.

РУССКИЙ

Компания BCM предпринимает активные действия по защите окружающей среды,
поэтому напоминаем вам, что:

В соответствии с директивой Европейского Союза (ЕС) по предотвращению

▶ CPU Confi guration

▶ Max CPUID Value Limit

The Max CPUID Value Limit BIOS feature allows you to circumvent
problems with older operating systems that do not support the Intel
Pentium 4 processor with Hyper-Threading Technology. When enabled,
the processor will limit the maximum CPUID input value to 03h when
queried, even if the processor supports a higher CPUID input value.
When disabled, the processor will return the actual maximum CPUID
input value of the processor when queried.

▶ Execute Disable Bit Capability

Intel’s Execute Disable Bit functionality can prevent certain classes of
malicious “buffer overfl ow” attacks when combined with a supporting
operating system. This functionality allows the processor to classify
areas in memory by where application code can execute and where it
cannot. When a malicious worm attempts to insert code in the buffer,
the processor disables code execution, preventing damage or worm
propagation.

▶ Hyper Threading Technology

The processor uses Hyper-Threading technology to increase transac­tion rates and reduces end-user response times. The technology treats
the two cores inside the processor as two logical processors that can
execute instructions simultaneously. In this way, the system perfor­mance is highly improved. If you disable the function, the processor will
use only one core to execute the instructions. Please disable this item if

▶ DVMT Mode Select

Intel’s Dynamic Video Memory Technology (DVMT) allows the system to dy­namically allocate memory resources according to the demands of the sys­tem at any point in time. The key idea in DVMT is to improve the effi ciency
of the memory allocated to either system or graphics processor.

It is recommended that you set this BIOS feature to DVMT Mode for maxi­mum performance. Setting it to DVMT Mode ensures that system memory
is dynamically allocated for optimal balance between graphics and system
performance.

fi xed amount of memory as dedicated graphics memory, as well as
allow more system memory to be dynamically allocated between the
graphics processor and the operating system.

“Pin8-GPO51” Status:addr A2 bit1, Setting:addr A1 bit1
“Pin9-GPI03” Status:addr F2 bit3
“Pin10-GPO52” Status:addr A2 bit2, Setting:addr A1 bit2

Note: GPIO pin connection design with 4 input and 4 output pins.

GPI is design for input, GPO is design for output

Example 1: Read data from GPIO “Pin3-GPI00”,

// the “Pin3-GPI00” status value is at address F2 bit 0,

Step 1. Enable SIO confi guration mode without timeout in between commands

Out(0x4e, 0x87); // (port, value), 0x4e for index
Out(0x4e, 0x87);

Step 2. Select LDN06 (GPIO) (LDN: Logic device number)

Out(0x4e, 0x07); // select entry page, 0x4e for index
Out(0x4f, 0x06); // select LDN06, 0x4f for data

Step 3. Set address to 0xF2

Out(0x4e, 0xF2); // 0x4e for index

Step 4. Get input data from port 0x4f

if (Inp(0x4f) & 0x01) !=0 ) // 0x4f for data, & 0x01 for bit0 of GPI00 input data
value = “high”;
else
value = “low”;

MX525D / MX525DC

4-9

Example 2: Set GPIO “Pin4-GPO04” output to “high”,

// the “Pin4-GPO04” output setting is at address F1 bit 4,

Step 1. Enable SIO confi guration mode without timeout in between commands

Out(0x4e, 0x87); // (port, value), 0x4e for index
Out(0x4e, 0x87);

Step 2. Select LDN06 (GPIO) (LDN: Logic device number)

Out(0x4e, 0x07); // select entry page, 0x4e for index
Out(0x4f, 0x06); // select LDN06, 0x4f for data

Step 3. Set address to 0xF1

Out(0x4e, 0xF1); //0x4e for index

Step 4. Get data from port 0x4f (Save current state)

Byte tmp = Inp(0x4f); //Read current data for adding the output in bit4

Step 5. Write data to port 0x4f (only set bit 4 to “high” and write back)

Out(0x4f, tmp|0x10); //0x4f for data

Example 3: Set GPIO “Pin4-GPO04” output to “low”,

// the “Pin4-GPO04” output setting is at address F1 bit 4,

Step 1. Enable SIO confi guration mode without timeout in between commands

Out(0x4e, 0x87); // (port, value), 0x4e for index
Out(0x4e, 0x87);

Step 2. Select LDN06 (GPIO) (LDN: Logic device number)

Out(0x4e, 0x07); // select entry page, 0x4e for index
Out(0x4f, 0x06); // select LDN06, 0x4f for data

Step 3. Set address to 0xF1

Out(0x4e, 0xF1); //0x4e for index

Step 4. Get data from port 0x4f (Save current state)

Byte tmp = Inp(0x4f); //Read current data for adding the output in bit4

Step 5. Write data to port 0x4f (only set bit 4 to “low” and write back)

Out(0x4f, tmp&0xEF);
