Key points for installing CPU and memory

1. CPU installation (Socket P)

Socket P is a 478 pin Micro FCPGA with a contact design. Installation steps:

Find the CPU socket and turn the locking screw counterclockwise until it is released.

Pay attention to aligning the golden triangle mark on the CPU with the triangle mark on the corner of the socket, and place the CPU vertically without sliding.

Gently press to ensure it is in place, then turn the locking screw clockwise to lock it in place.

Important: It is necessary to install a suitable heat sink (motherboard with CPU fan interface CPUFAN1, 4-pin PWM), apply thermal grease to ensure good heat dissipation. Overheating can seriously damage the CPU.

2. System memory (DDR2)

Two 240 pin DIMM slots, supporting dual channel DDR2 533/667 MHz, with a maximum capacity of 4GB (up to 2GB per pin). Suggest using same brand and same CL delayed strips. During installation, open the buckle outward and insert it vertically into the anti mistake notch until the buckle is securely fastened. Attention: If installing two memory modules, they should be inserted first into DIMM1 and DIMM2 (the manual does not specify the color of the dual channel slots, but they are usually adjacent slots).

Key jumper and connector configuration

1. CMOS Clear (JBAT1)

Short circuit 2-3 pins to clear CMOS and restore to 1-2 normal mode. Used when BIOS settings are incorrect and prevent startup.

2. CF mode selection (JCF_SEL1)

Used to select the working mode (Master/Slave) of CF card, specific settings need to refer to the screen printing on the board, usually used for IDE channel master-slave configuration.

3. COM port power jumper (J5, J6)

J5 corresponds to COM1, J6 corresponds to COM2, and the 9th pin can be configured as+5V or+12V (or VCC) to supply power to serial devices (such as touch screens). Please refer to Figure 2-13 in the manual for the specific position of the jumper cap.

4. LVDS power selection (J7)

The power supply voltage (+3.3V or+5V) for the LCD panel used to select the LVDS interface needs to be set according to the panel specifications.

5. Chassis Intrusion Detection (JCASE1)

Can connect the chassis to turn on the detection switch, the system records the intrusion status and displays a warning in the BIOS. To clear the warning, set "Chassis Intrusion" to Reset in the Super IO configuration of the BIOS.

Deep analysis of BIOS settings

MI-965 uses AMI BIOS (8Mb Flash), press Del to enter when booting up. The following are key settings:

1. Main menu

Driver installation process (Windows XP 32-bit example)

The CD directory is as follows (X: is the drive letter):

Chipset: CHIPSET Intel InF8.3.0.1013 infins_autol.exe

Graphics card: SVGA Intel GM965 Winxp32 setup.exe

Network card: NETWORK Intel autorun.exe (drivers 82573L and 82566DC)

Sound card: SOUND REALTEK ALC888 windows R187 etup.exe

TPM：TPMWin32setup.exe

Suggested installation sequence: chipset → graphics card → network card → sound card → TPM (optional), with a prompt to restart after each installation step. For Windows 7/Vista, you need to download the corresponding version driver from the official website (or use a universal driver).

Watch dog timer programming

The WDT of MI-965 is controlled by Super I/O (Winbond/Nuvoton) and programmed similarly to M-302, but the logic device number may be the same (usually 0x08). Assembly example (convertible to C language):

#define SIO_IDX 0x2E

#define SIO_DTA 0x2F

void EnableWDT(unsigned char timeout_sec) 

{//Enter configuration mode

outportb(SIO_IDX, 0x87);

outportb(SIO_IDX, 0x87);   

//Select logical device 8

outportb(SIO_IDX, 0x07);

outportb(SIO_DTA, 0x08);   

//Set timeout value (seconds), write CRF6 (0xF6)

outportb(SIO_IDX, 0xF6);

outportb(SIO_DTA, timeout_sec);  

//Exit configuration mode

outportb(SIO_IDX, 0xAA);

}//The application layer needs to periodically call the following code to reset the timer (rewrite the same value)

outportb(SIO_IDX, 0xF6);

outportb(SIO_DTA, timeout_sec);

The system will automatically reset after timeout. If it needs to be set to minutes, modify the corresponding register (refer to the manual or Super I/O data manual for details).

POST code and troubleshooting

The POST code of AMI BIOS can be viewed through the PCI diagnostic card. Key code:

03~08: Early CPU/chipset initialization, if stuck, it is mostly due to CPU or memory issues.

C0~C5: Multi processor initialization, generally no problem.

40: Detect serial ports, parallel ports, etc. If stopped, troubleshoot I/O conflicts.

75: Initialize INT 13 and prepare to boot.

84~85: Record and display errors.

A7: Display system configuration, manual intervention may be required if stuck.

AB: Prepare BBS (BIOS Boot Specification) boot.

00: Enter the operating system loader (INT 19h) and start normally.

Common faults:

Phenomenon countermeasures

Check if the CPU is properly installed and if the memory is securely plugged in when there is no display when powered on; Clear CMOS; Confirm that the monitor is connected to the VGA port (if no dedicated monitor is installed)

Cycle restart after startup, insufficient power supply or CPU overheating; Check the fan connection; Load FailSafe Defaults

The hard drive cannot recognize SATA mode set to AHCI but does not come with a pre installed driver; Replace the data cable or SATA port; Check the power cord

USB device not recognized. Check if Legacy USB Support is enabled; Try replacing the rear USB port

Check if the Boot Graphics Adapter Priority in BIOS is set to Onboard or Auto when there is no signal from the integrated graphics card

Audio silence confirmation HDA Controller enabled; Check if the front audio jumper (AAFP) is connected correctly; Restart after driver installation

Check if the watchdog accidentally resets and if the application is reset regularly; Is the timeout value too short

Special features and advanced extensions

Dual independent display: GMA X3100 supports various combinations such as CRT+LVDS, CRT+TV-OUT, etc., set in the Boot Display Device of BIOS, suitable for digital signage.

LVDS interface: 40 pin header, supports 24 bit single channel, can select panel power supply voltage through J7 jumper, needs to be matched with backlight control signals (L_BKLTCTL, L_BKLTEN).

TV-OUT: Output composite video (CVBS) through optional bracket, suitable for old display devices.

GPIO: 16 channel digital I/O (J4), which can be used to control external relays or read sensor status, operated through the GPIO register of Super I/O.

TPM: Supports secure boot and encrypted storage, requires driver installation and activation of Trusted Computing in BIOS.
