1.8 Safety Precautions Warning! Always completely disconnect the power cord from your chassis whenever you work with the hardware. Do not make connections while the power is on. Sensitive electronic components can be damaged by sudden power surges. Only experienced electronics personnel should open the PC chassis. Caution! Always ground yourself to remove any static charge before touching the CPU card. Modern electronic devices are very sensitive to static electric charges.
1.9 Jumper Settings This section provides instructions on how to configure your card by setting jumpers. It also includes the card's default settings and your options for each jumper. 1.9.1 How to set jumpers You configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them.
1.9.3 CMOS clear (J6) The PCA-6175 CPU card contains a jumper that can erase CMOS data and reset the system BIOS information. Normally this jumper should be set with pins 1-2 closed. If you want to reset the CMOS data, set J6 to 2-3 closed for just a few seconds, and then move the jumper back to 1-2 closed. This procedure will reset the CMOS to its default setting. Table 1-4: CMOS clear jumper settings (J6) Function Jumper setting Keep CMOS data 1-2 closed Clear CMOS data 2-3 closed 1 1 1.9.
1.9.5 CPU bus clock select (J11) The CPU clock varies according to the Pentium® II processor's CPU bus clock. There are two settings for the CPU clock, 66.6 MHz and 75 MHz. Table 1-6: CPU clock select jumper settings (J11) Function Jumper setting 66.6 MHz 1-2 closed 75 MHz 2-3 closed 1 1 Note: 14 75 MHz exceeds the product's specifications.
1.9.6 DiskOnChip® 2000 Flash disk address select (J12) The PCA-6175 includes a 32-pin socket for M-System's DiskOnChip 2000 Flash disk module. This revolutionary solid state disk enables critical system information to be stored within an on-board Flash disk for virtually instantaneous data access. You must specify the memory address you wish to use for your DiskOnChip 2000 Flash disk module by setting jumper (J12).
1.10 System Memory The top-left edge of the PCA-6175 contains three sockets for 168-pin dual inline memory modules (DIMMs). All three sockets use 3.3 V unbuffered synchronous DRAMs (SDRAM). DIMMs are available in capacities of 16, 32, 64 or 128 MB. The sockets can be filled in any combination with DIMMs of any size, giving your PCA-6175 single board computer between 16 and 384 MB of memory.
1.10.2 Supplementary information about DIMMs Your PCA-6175 can accept four kinds of memory chips: EDO (with or without parity), and SDRAM (with or without parity). Also: • SDRAM chips are usually thinner and have higher pin density than EDO chips. • The BIOS displays EDO and SDRAM memory on the boot-up screen. • Chips with 9 chips/side support parity; chips with 8 chips/side do not support parity. • Single-sided modules are typically 16 or 64 MB; double-sided modules are usually 8, 32 or 128 MB.
1.11 Memory Installation Procedures To install DIMMs, first make sure the two handles of the DIMM socket are in the "open" position. i.e. The handles remain outward. Slowly slide the DIMM module along the plastic guides on both ends of the socket. Then press the DIMM module right down into the socket, until you hear a click. This is when the two handles have automatically locked the memory module into the correct position of the DIMM socket. (See Figure 1-3.
1.12 Cache Memory Since the second level cache has been embedded into the Pentium® II CPU, you do not have to take care of either SRAM chips or SRAM modules. The built-in second level cache in the Pentium II yields much higher performance than the external cache memories. The cache size in the Pentium II CPU is either 256 KB or 512 KB. Normally, for workstation and server application, the 256 KB version is enough. However, if your system is for heavy duty applications, the 512 KB version will help a lot.
1.13 Mounting the CPU and Cooling Modules The Pentium® II is a module-type CPU which runs at high speeds, for exampe 233 ~ 333 MHz, so the cooling mechanism becomes critical for system reliability. There are two types of cooling methods: one with a cooling fan attached to the heat sink of the Pentium II module, the other with a huge heat sink without any cooling fan attached. Both cooling methods for the Pentium II require a "retention module" to firmly fix the Pentium II CPU to slot 1.

1.14 On-board Support Bracket Advantech's PCA-6175 Pentium® II also includes an on-board metal bracket to provide balanced support for the Pentium II processor cartridge.
CHAPTER 2 Connecting Peripherals This chapter tells how to connect peripherals, switches and indicators to the PCA-6175 board. You can access most of the connectors from the top of the board while it is installed in the chassis. If you have a number of cards installed, or your chassis is very tight, you may need to partially remove the card to make all the connections.
2.1 Primary (CN6) and Secondary (CN7) IDE Connectors You can attach up to four IDE (Integrated Device Electronics) drives to the PCA-6175’s internal controller. The primary (CN6) and secondary (CN7) connectors can each accommodate two drives. Wire number 1 on the cable is red or blue and the other wires are gray. Connect one end to connector CN6 or CN7 on the CPU card. Make sure that the red/blue wire corresponds to pin 1 on the connector (in the upper right hand corner).
2.3 Parallel Port Connector (CN8) The parallel port is normally used to connect the CPU card to a printer. The PCA-6175 includes an on-board parallel port, accessed through a 26-pin flat-cable connector, CN8. The card comes with an adapter cable which lets you use a traditional DB-25 connector. The cable has a 26-pin connector on one end and a DB-25 connector on the other, mounted on a retaining bracket. The bracket installs at the end of an empty slot in your chassis, giving you access to the connector.
2.5 Serial Ports (CN9: COM1; CN10: COM2) The PCA-6175 offers two serial ports, CN1 as COM1 and CN2 as COM2. These ports can connect to serial devices (such as a mouse, printers, and so on) or to a communication network. Table 2-1: Serial port connections (COM1, COM2) Connector CN9 CN10 Ports COM1 COM2 Address 3F8*, 3E8 2F8*, 2E8 Interrupt IRQ4 IRQ3 * default settings The IRQ and address ranges for both ports are fixed.
2.6 Front Panel Connectors (CN2, CN3, CN4, J1 and J2) There are several external switches to monitor and control the PCA-6175. 2.6.1 Keyboard lock and power on LED (CN2) CN2 is a 5-pin connector for the keyboard lock and power on LED connection. Refer to Appendix B.12 for detailed information on the pin assignments. If a PS/2 power supply is used, the system's power LED status will be one of the following: PS/2 Power Mode LED Status System On On System Suspend Flashes eight times/sec.
2.7 ATX Power Control Connectors (J7 and J1) 2.7.1 ATX feature connector (J7) and soft power switch connector (J1) The PCA-6175 can support an advanced soft power switch function if an ATX power supply is used. To enable the soft power switch function: 1. Take the specially designed ATX-to-PS/2 power cable out of the PCA-6175's accessory bag. 2. Connect the 3-pin plug of the cable to J7 (ATX feature connector). 3. Connect the power on/off button to J1. (A momentary type of button should be used.
2.7.2 Controlling the soft power switch It is easy to control the ATX soft power switch. Pushing the button once will switch the system between the "On" and "Suspend" power modes. Pushing the button for more than 4 seconds while in the "On" mode will turn the system off. Users can also identify the current power mode through the system's power LED, as indicated below: ATX Power Mode LED Status 2.8 System On On System Suspend Flashes eight times/sec. System Off Flashes once/sec.
2.11 External Suspend Switch Lead (SMI) (J3) This allows the user to manually place the system into a suspend mode or "Green" mode when the system is not in use. System activity is decreased to save electricity and prolong the life of certain components. The 2-pin connector connects to the case-mounted suspend switch. If you do not have a switch for the connector, you may use the "turbo switch", because it does not have any other function. SMI is activated when it detects a "short to open" moment.
CHAPTER 3 Award BIOS Setup This chapter describes how to set the card’s BIOS configuration data.
3.1 Introduction Award’s BIOS ROM has a built-in setup program that allows users to modify the basic system configuration.
