29 Chapter 2 Installation Install CPU Please install the CPU as follows (See the figure below): Aim the first pin of the CPU (with triangular symbol) with the gap on the CPU socket and insert the CPU into the socket. After the CPU is installed properly, tighten the screws on the CPU socket in clockwise direction via screwdriver. Pay attention to the strength and do not destroy the CPU socket. Install CPU Fan Please install the CPU fan as follows: (See the figure below): Firstly, aim the backplane of the cooling fin (see figure 4) with the fixing holes on the rear of the CPU card; Connect the cooling fin (see figure 5) with the backplane in the front and fix them; pay attention that the surface between the cooling fin and the CPU crystal wafer is well contacted; Fix the cooling fin with two screws on the cross (do not tighten it) and then the other two screws; then tighten the four screws; Lastly, connect the fan power cable onto the fan socket on the CPU card. Note! It is recommended to use cooling fan authenticated by Intel; before installing the fan, smear the heat sink compound on the surface between CPU and the fan cooling fin to improve the heat dissipation performance; always check whether the fan is operating normally to ensure the heat dissipation within the chassis. When holding a board, please hold the edge instead of the cooling fin. EC5 1712CLDNA(B) 25

30 Chapter 3 BIOS Setup Chapter 3 BIOS Setup BIOS Overview BIOS (Basic Input and Output System) is solidified in the flash memory on the CPU board. Its main functions include: initialize system hardware, set the operating status of the system components, adjust the operating parameters of the system components, diagnose the functions of the system components and report failures, provide hardware operating and controlling interface for the upper level software system, guide operating system and so on. BIOS provides users with a human computer interface in menu style to facilitate the configuration of system parameters for users, control power management mode and adjust the resource distribution of system device, etc. Setting the parameters of the BIOS correctly could enable the system operating stably and reliably; it could also improve the overall performance of the system at the same time. Inadequate even incorrect BIOS parameter setting will decrease the system operating capability and make the system operating unstably even unable to operate normally. BIOS Parameter Setup Prompt message for BIOS setting may appear once powering on the system. At that time (inefficient at other time), press the key specified in the prompt message (usually <Del>) to enter BIOS setting. When the BIOS setting in CMOS is destroyed, system may also require entering BIOS setting or selecting certain default value. All the setup values modified by BIOS are saved in the CMOS storage in system. The CMOS storage is powered by battery; unless clearing CMOS contents, or else its contents will not be lost even if powered off. Note! BIOS setting will influent the computer performance directly. Setting parameter improperly will cause damage to the computer; it may even unable to power on. Please use the internal default value of BIOS to restore the system. Our company is constantly researching and updating BIOS, its setup interface may be a bit different. The figure below is for reference only; it may be different from your BIOS setting in use. 26 EC5 1712CLDNA(B)

43 Chapter 3 BIOS Setup The System Resources Managed by BIOS under x86 Platform We define three kinds of system resources here: I/O port address, IRQ interrupt number and DMA number. 1. DMA Level DMA0 DMA1 DMA2 DMA3 DMA4 DMA5 DMA6 DMA7 Function Not Assigned Not Assigned Not Assigned Not Assigned (Sometimes used for hard disk) Used for the cascade of DMAC Not Assigned Not Assigned Not Assigned 2. APIC Advanced programmable interrupt controller. Most motherboards above P4 level support APIC and provide more than 16 interrupt sources, like IRQ16 IRQ23; while some others can have up to 28 interrupt sources. However, relevant OS are required to support that function, and currently, only the OS above Windows 2000 could support that function. 3. IO Port Address There are 16 I/O address lines for X86, from 0 ~ 0FFFFh; and there is altogether 64K I/O address space. In traditional ISA interface, only the first 1024 ports are in use (0000~03FFh) and the port number above 0400h are used by PCI interface and EISA EC5 1712CLDNA(B) 39

44 Chapter 3 BIOS Setup interface. Each peripheral device shall occupy a part of the I/O address. The table below lists the I/O interfaces used roughly in X86 platform.

45 Chapter 3 BIOS Setup 4. IRQ Assignment Table There are 15 interrupt sources in the system. Some are exclusively occupied by the system device. Only the ones which are not exclusively occupied can be distributed. The ISA devices claim to engross the interrupt. Only the plug and play ISA devices can be distributed by the BIOS or the OS. And several PCI devices can share one interrupt through the distribution of BIOS or OS. The diagram below shows parts of the interrupt distribution, but it does not show the interrupts of the PCI devices.

47 Appendix Appendix Watchdog Programming Guide This board provides a programmable watchdog timer (WDT) up to 255 levels. Watchdog timer overtime event can be programmed to reset system or generate maskable interrupts. The available IRQ numbers for this board are: 3, 4, 5, 7, 9, 10 and 11. Before using, please modify the corresponding IRQ number in PCIPnP of BIOS Setup interface into Reserved. The following gives an example for WDT programming in C language. The steps to program WDT are listed as follows: Enter WDT programming mode Set WDT operating mode/enable WDT/disable WDT (1) Enter WDT Programming Mode #define INDEX_PORT 0x2E #define DATA_PORT 0x2F outportb(index_port, 0x87); outportb(index_port, 0x87); outportb(index_port, 0x07); outportb(data_port, 0x08); outportb(index_port, 0x30); outportb(data_port, 0x01); (2) Configure the Operating Mode for WDT, Reset or Interrupt unsigned char oldval; outportb(index_port,0x2d); oldval = inportb(data_port); EC5 1712CLDNA(B) 43

Time by Minute outportb(index_port,0xf5); outportb(data_port,0x08); b. Time by Second outportb(index_port,0xf5); outportb(data_port,0x00); (4) Enable/Disable WDT a. Enable WDT outportb(index_port,0xf6); outportb(data_port,time_out_value); /*Please replace the constant TIME_OUT_VALUE with the unit number of timeout value(0x01~0xff)*/ b.

93 第三章 BIOS 功能简介 x86 平台下 BIOS 所要管理的系统资源 这里的系统资源我们定义三种 :I/O 端口地址,IRQ 中断号和 DMA 号 1. DMA 级别 功能 DMA0 未分配 DMA1 未分配 DMA2 未分配 DMA3 未分配 ( 有时用于硬盘 ) DMA4 用于 DMAC 的级联 DMA5 未分配 DMA6 未分配 DMA7 未分配 2. APIC 高级可编程中断控制器 在现代 P4 以上级别的主板中, 大都支持 APIC, 可以提供多于 16 个中断源, 如 IRQ16 IRQ23, 部分主板如支持 PCI-X 的主板可以有多达 28 个中断源 但要启用该功能必须相应的操作系统支持, 目前只有 windows 2000 以上的操作系统支持 3. IO 端口地址 X86 的 I/O 地址线只设计 16 条, 从 0~0FFFFh,I/O 地址空间总共有 64K, 在传统的 ISA 接口, 只使用到前面的 1024 个 (0000~03FFh),0400h 以上的端口为 PCI 接口与 EISA 接口所使用 每一外围设备都会占用一段 I/O 地址空间 下表给出了 X86 平台大致上所要用到的 I/O 接口列表 EC5-1712CLDNA(B)
