CHAPTER Installation 2 This chapter describes how to set up the main board hardware, including instructions on setting jumpers and connecting peripherals, switches, and indicators. Be sure to read all the safety precautions before you begin the installation procedure.
Jumpers and connectors Connectors on the board link it to external devices such as hard disk drives, a keyboard, or floppy drives. In addition, the board has a number of jumpers that allow you to configure your system to suit your application. The following tables list the function of each of the board's jumpers and connectors.

Setting jumpers You can 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. To “close” a jumper you connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3. In this case you would connect either pins 1 and 2 or 2 and 3.
CPU installing and upgrading You can upgrade to a more powerful Pentium II CPU at any time. Simply remove the old CPU, install the new one, and set the jumpers for the new CPU speed. Warning! Always disconnect the power cord from your chassis when you are working on it. Do not make connections while the power is on as sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics personnel should open the PC chassis.
Mounting the CPU and cooling Modules The Pentium II is a module-type CPU which runs at high speeds, for example 233 ~ 450 MHz, so the cooling mechanism becomes critifal for system reliability. These 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.
Mounting CPU and cooling modules - Step 1 Step 1 Mounting CPU and cooling modules - Step 2 Step 2 Chapter 2 Installation 17
Installing DRAM (DIMMs) System Memory The left edge of the PCM-7890 contains a socket for 168-pin dual inline memory module (DIMM). The socket uses 3.3 V unbuffered synchronous DRAM (SDRAM). DIMM is available in capacities of 16, 32, 64, or 128 MB. The socket can be filled in the DIMM of any size, giving your PCM-7890 single board computer between 16 and 128 MB of memory. Supplementary information about DIMM Your PCM-7890 can accept both regular and PC-100 SDRAM DIMM Module(with or without parity).
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.
System temperature thermal sensor (J1) This jumper is reserved to connect a system temperature thermal sensor in order to detect the system temperature. CPU frequency ratio (J3) CPU core frequency = CPU frequency ratio (3~5.5) * External bus clock (66 or 100 MHz) CPU frequency ratio (J3) 3x 3.5x 4x 1 3 5 1 3 5 1 3 5 2 4 6 2 4 6 2 4 6 4.5x 5x 5.

Caution: the DOC may be permanently damage if it is installed incorrectly. 3. Set the jumper for the memory address of the DOC.
CHAPTER 3 Award BIOS Setup This chapter describes how to configure the BIOS for the PCM-7890.
Starting setup The Award BIOS is immediately activated when you first turn on the computer. The BIOS reads system configuration information in CMOS RAM and begins the process of checking out the system and configuring it through the power-on self test (POST). When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands control of system operations to it.

Standard CMOS setup When you choose the STANDARD CMOS SETUP option from the INITIAL SETUP SCREEN menu, the screen below is displayed.
This standard setup menu allows users to configure system components such as the date, time, hard disk drive, floppy drive, display, and memory. Online help for each field can be accessed by pressing F1. Date and Time Configuration The BIOS determines the day of the week from the other date information. This field is for information only. Press the left or right arrow key to move to the desired field (date, month, year).
selecting the drive type are available: 1.Match the specifications of your installed IDE hard drive(s) with the preprogrammed values for drive types 1 through 45. 2.Select USER and enter values into each drive parameter field. 3.Use the IDE HDD AUTO DECTECTION function in Setup. Here is a brief explanation of drive specifications: •Type: The BIOS contains a table of pre-defined drive types.
- LBA (Logical Block Addressing): During drive accesses, the IDE controller transforms the data address described by sector, head, and cylinder number into a physical block address, significantly improving data transfer rates. For drives with greater than 1024 cylinders. Drive A Drive B Select the correct specifications for the diskette drive(s) installed in the computer. None 360K, 5.25 in 1.2M, 5.25 in 720K, 3.5 in 1.44M, 3.5 in 2.88M, 3.
Pannel: This selection item allows user to select LCD BIOS to match the LCD types.
Halt On During the power-on-self-test (POST), the computer stops if the BIOS detects a hardware error. You can tell the BIOS to ignore certain errors during POST and continue the boot-up process. These are the selections: • No errors: POST does not stop for any errors. • All errors If: the BIOS detects any non-fatal error, POST stops and prompts you to take corrective action.
•Extended Memory Above the 1-MB boundary. Early IBM personal computers could not use memory above 1 MB, but current PCs and their software can use extended memory. •Other Memory Between 640 KB and 1 MB; often called High memory. DOS may load terminate-and-stay-resident (TSR) programs, such as device drivers, in this area, to free as much conventional memory as possible for applications. Lines in your CONFIG.SYS file that start with LOADHIGH load programs into high memory.
BIOS features setup By choosing the BIOS FEATURES SETUP option from the INITIAL SETUP SCREEN menu, the screen below is displayed.
The displayed configuration is based on the manufacturer's SETUP DEFAULTS settings. Virus Warning When enabled, you receive a warning message if a program (specifically, a virus) attempts to write to the boot sector or the partition table of the hard disk drive. You should then run an antivirus program. Keep in mind that this feature protects only the boot sector, not the entire hard drive. NOTE: Many disk diagnostic programs that access the boot sector table can trigger the virus warning message.
Boot Sequence The original IBM PCs loaded the DOS operating system from drive A (floppy disk), so IBM PC-compatible systems are designed to search for an operating system first on drive A, and then on drive C (hard disk). However, the BIOS now offers many boot sequence options. Swap Floppy Drive This field is effective only in systems with two floppy drives. Selecting enabled assigns physical drive B to logical drive A, and physical drive A to logical drive B.
PS/2 Mouse Function Control If your system has a PS/2 mouse port and you install a serial pointing device, select Disabled. Shadow Software that resides in a read-only memory (ROM) chip on a device is called firmware. The AwardBIOS permits shadowing of firmware such as the system BIOS, video BIOS, and similar operating instructions that come with some expansion peripherals, such as, for example, a SCSI adaptor.
CHIPSET features setup By choosing the CHIPSET FEATURES SETUP option from the INITIAL SETUP SCREEN menu, the screen below is displayed.
The displayed configuration is based on the manufacturer's SETUP DEFAULTS settings. This section allows you to configure the system based on the specific features of the installed chipset. This chipset manages bus speeds and access to system memory resources, such as SDRAM. It also coordinates communications between the conventional ISA bus and the PCI bus. It must be stated that these items should never need to be altered.
EDO RASx# Wait State The board designer may elect to insert one additional wait state before RAS# is asserted for row misses, thus allowing one additional MAX[13:0] setup time to RASx# assertion. This field applies only if EDO DRAM is installed in the system. SDRAM RAS-to-CAS Delay This field lets you control the number of DCLKs between a Row Activate command and a read or write command.
Video BIOS Cacheable Selecting Enabled allows caching of the video BIOS ROM at C0000h to C7FFFh, resulting in better video performance. However, if any program writes to this memory area, a system error may result. Video RAM Cacheable Selecting Enabled allows caching of the video memory (RAM) at A0000h to AFFFFh, resulting in better video performance. However, if any program writes to this memory area, a memory access error may result.
Auto Detect DIMM/PCI Clk When the Auto Detect DIMM/PCI clk enable, the Utility will automatically detect the DIMM/PCI clock in your system. Spread Spectrum When the system clock generator pulses, the extreme values of the pulse generate excess EMI. Enabling pulse spectrum spread modulation changes the extreme values from spikes to flat curves, thus reducing EMI.
Power management setup By choosing the POWER MANAGEMENT option from the INITIAL SETUP SCREEN menu, the screen below is displayed.
The displayed configuration is based on the manufacturer's SETUP DEFAULTS settings. Power Management This option allows you to select the type (or degree) of power saving for Doze, Standby, and Suspend modes. This table describes each power management mode: Max Saving User Define Min Saving 68 PCM-7890 User Manual Maximum power savings. Only Available for SL CPUs. Inactivity period is 1 minute in each mode. Set each mode individually. Select time-out periods in the section for each mode, below.
PM Control by APM If Advanced Power Management (APM) is installed on your system, selecting Yes gives better power savings. Video Off Method Determines the manner in which the monitor is blanked. V/H SYNC+Blank System turns off vertical and horizontal synchronization ports and writes blanks to the video buffer. DPMS Support Select this option if your monitor supports the Display Power Management Signaling (DPMS) standard of the Video Electronics Standards Association (VESA).
Standby Mode After the selected period of system inactivity, the CPU clock stops, the hard drive enters an idle state, and the L2 cache enters a powersave mode. All other devices still operate at full speed. Suspend Mode After the selected period of system inactivity, the chipset enters a hardware suspend mode, stopping the CPU clock and possibly causing other system devices to enter power management modes.
IRQ8 Break [Event From] Suspend You can select Enabled or Disabled for monitoring of IRQ8 (the Real Time Clock) so it does not awaken the system from Suspend mode. Reload Global Timer Events When Enabled, an event occurring on each device listed below restarts the global timer for Standby mode.
PNP/PCI configuration setup By choosing the PNP/PCI CONFIGURATION SETUP option from the initial SETUP SCREEN menu, the screen below is displayed.
The displayed configuration is based on the manufacturer's SETUP DEFAULTS settings. PNP OS Installed Select Yes if the system operating environment is Plug-and-Play aware (e.g., Windows 95). Resources Controlled By The Plug and Play AwardBIOS can automatically configure all the boot and Plug and Play-compatible devices. If you select Auto, all the interrupt request (IRQ) and DMA assignment fields disappear, as the BIOS automatically assigns them.
Legacy ISA Devices compliant with the original PC AT bus specification, requiring a specific DMA channel PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for PCI or ISA bus architecture. PCI IRQ Activated by Leave the IRQ trigger set at Level unless the PCI device assigned to the interrupt specifies Edge-triggered interrupts. Assign IRQ for VGA If you are not using your system's VGA controller, select Disabled to free the IRQ resource.
Load BIOS defaults/Load setup defaults LOAD BIOS DEFAULTS loads the default system values directly from ROM. The BIOS DEFAULTS provides the most stable settings, though they do not provide optimal performance. LOAD SETUP DEFAULTS, on the other hand, provides for maximum system performance. If the stored record created by the setup utility becomes corrupted (and therefore unusable), BIOS defaults will load automatically when you turn the PCM-7890 on.
Integrated peripherals setup By choosing the INTEGRATD PERIPHERALS option from the initial SETUP SCREEN menu, the screen below is displayed.
The displayed configuration is based on the manufacturer's SETUP DEFAULSTS settings. IDE HDD Block Mode Select Enabled only if your hard drives support block mode. IDE PIO Modes (Primary Master/Slave) The four IDE PIO (Programmed Input/Output) fields let you set a PIO mode (0-4) for each of up to four IDE devices that the internal PCI IDE interface supports. Modes 0 through 4 provide successively increased performance. In Auto mode, the system automatically determines the best mode for each device.
Onboard FDC Controller Select Enabled if your system has a floppy disk controller (FDC) installed on the system board and you wish to use it. If you install an add-in FDC or the system has no floppy drive, select Disabled in this field. Onboard Serial Ports (1, 2) Select a logical COM port address for the first and second serial ports. RxD, TxD Active Consult your IR peripheral documentation to select the correct setting of the TxD and RxD signals. ECP Mode Use DMA Select a DMA channel for the port.
Supervisor/User password setting You can set either SUPERVISOR or USER PASSWORD, or both of them. The difference between the two is that the supervisor password allows unrestricted access to enter and change the options of the setup menus, while the user password only allows entry to the program, but not modify options.
When you select this function, a message appears at the center of the screen: ENTER PASSWORD: Type the password, up to eight characters, and press Enter. Typing a password clears any previously entered password from CMOS memory. Now the message changes: CONFIRM PASSWORD: Again, type the password and press Enter. To abort the process at any time, press Esc.
IDE HDD auto detection The IDE HDD AUTO DETECTION utility can automatically detect the IDE hard disk installed in your system. You can use it to selfdetect and/or correct the hard disk type configuration.
Save & exit setup If you select this option and press , the values entered in the setup utility will be recorded in the chipset's CMOS memory. The microprocessor will check this every time you turn your system on and compare this to what it finds as it checks the system. This record is required for the system to operate.
