INSTALLATIONS Installing the CPU The MB890 board supports a Socket 479 processor socket for Intel® Pentium® M or Celeron® M processors. The processor socket comes with a screw to secure the processor. As shown in the left picture below, loosen the screw first before inserting the processor. Place the processor into the socket by making sure the notch on the corner of the CPU corresponds with the notch on the inside of the socket. Once the processor has slide into the socket, fasten the screw.
INSTALLATIONS Installing the Memory The MB890 board supports one DDR memory sockets for a maximum total memory of 1GB in DDR memory type. The memory module capacities supported are 128MB, 256MB, 512MB and 1GB. The following table lists the supported DDR DIMM configurations. Intel® 855GME supports configurations defined in the JEDEC DDR DIMM specification only. Non-JEDEC standard DIMMs such as double-sided x16 DDR SDRAM DIMMs are not supported.

BIOS SETUP BIOS Setup This chapter describes the different settings available in the Award BIOS that comes with the board. The topics covered in this chapter are as follows: BIOS Introduction ........................................................................ 24 BIOS Setup ................................................................................... 24 Standard CMOS Setup ................................................................. 26 Advanced BIOS Features .................................
BIOS SETUP BIOS Introduction The Award BIOS (Basic Input/Output System) installed in your computer system’s ROM supports Intel processors. The BIOS provides critical low-level support for a standard device such as disk drives, serial ports and parallel ports. It also adds virus and password protection as well as special support for detailed fine-tuning of the chipset controlling the entire system.
BIOS SETUP Phoenix - AwardBIOS CMOS Setup Utility Standard CMOS Features Advanced BIOS Features Advanced Chipset Features Integrated Peripherals Power Management Setup PnP/PCI Configurations PC Health Status Frequency/Voltage Control Load Fail-Safe Defaults Load Optimized Defaults Set Supervisor Password Set User Password Save & Exit Setup Exit Without Saving ESC : Quit F10 : Save & Exit Setup Ç È Æ Å : Select Item Time, Date, Hard Disk Type… The section below the setup items of the Main Menu display
BIOS SETUP Standard CMOS Setup “Standard CMOS Setup” choice allows you to record some basic hardware configurations in your computer system and set the system clock and error handling. If the motherboard is already installed in a working system, you will not need to select this option. You will need to run the Standard CMOS option, however, if you change your system hardware configurations, the onboard battery fails, or the configuration stored in the CMOS memory was lost or damaged.
BIOS SETUP Time The time format is: Hour : 00 to 23 Minute : 00 to 59 Second : 00 to 59 To set the time, highlight the “Time” field and use the / or +/- keys to set the current time. IDE Primary HDDs / IDE Secondary HDDs The onboard PCI IDE connectors provide Primary and Secondary channels for connecting up to four IDE hard disks or other IDE devices. Each channel can support up to two hard disks; the first is the “Master” and the second is the “Slave”.
BIOS SETUP Video This field selects the type of video display card installed in your system. You can choose the following video display cards: EGA/VGA For EGA, VGA, SEGA, SVGA or PGA monitor adapters. (default) CGA 40 Power up in 40 column mode. CGA 80 Power up in 80 column mode. MONO For Hercules or MDA adapters. Halt On This field determines whether or not the system will halt if an error is detected during power up. No errors The system boot will not be halted for any error that may be detected.
BIOS SETUP Advanced BIOS Features This section allows you to configure and improve your system and allows you to set up some system features according to your preference.
BIOS SETUP First/Second/Third Boot Device These fields determine the drive that the system searches first for an operating system. The options available include Floppy, LS120, HDD-0, SCSI, CDROM, HDD-1, HDD-2, HDD-3, ZIP100, USB-FDD, USB-CDROM, USB-HDD and Disable. Boot Other Device These fields allow the system to search for an OS from other devices other than the ones selected in the First/Second/Third Boot Device.
BIOS SETUP Security Option This field allows you to limit access to the System and Setup. The default value is Setup. When you select System, the system prompts for the User Password every time you boot up. When you select Setup, the system always boots up and prompts for the Supervisor Password only when the Setup utility is called up. APIC Mode APIC stands for Advanced Programmable Interrupt Controller. The default setting is Enabled.
BIOS SETUP Advanced Chipset Features This Setup menu controls the configuration of the chipset.
BIOS SETUP DRAM RAS# Precharge This option sets the number of cycles required for the RAS to accumulate its charge before the SDRAM refreshes. The default setting for the Active to Precharge Delay is 3. DRAM Data Integrity Mode Select ECC if your memory module supports it. The memory controller will detect and correct single-bit soft memory errors. The memory controller will also be able to detect double-bit errors though it will not be able to correct them.
BIOS SETUP AGP Aperture Size The field sets aperture size of the graphics. The aperture is a portion of the PCI memory address range dedicated for graphics memory address space. Host cycles that hit the aperture range are forwarded to the AGP without any translation. The default setting is 64M. On-Chip VGA The default setting is Enabled. On-Chip Frame Buffer Size The default setting is 32MB. The options available include 1MB, 4MB, 8MB and 16MB. Boot Display The default setting is CRT+DVI.
BIOS SETUP Integrated Peripherals This section sets configurations for your hard disk and other integrated peripherals. The first screen shows three main items for user to select. Once an item selected, a submenu appears. Details follow.

BIOS SETUP Power Management Setup The Power Management Setup allows you to save energy of your system effectively.
BIOS SETUP Video Off Method This field defines the Video Off features. There are three options. V/H SYNC + Blank Default setting, blank the screen and turn off vertical and horizontal scanning. DPMS Allows BIOS to control the video display. Blank Screen Writes blanks to the video buffer. Video Off In Suspend When enabled, the video is off in suspend mode. The default setting is Yes. Suspend Type The default setting for the Suspend Type field is Stop Grant.
BIOS SETUP Power On by Ring This field enables or disables the power on of the system through the modem connected to the serial port or LAN. Resume by Alarm This field enables or disables the resumption of the system operation. When enabled, the user is allowed to set the Date and Time. Reload Global Timer Events The HDD, FDD, COM, LPT Ports, and PCI PIRQ are I/O events that can prevent the system from entering a power saving mode or can awaken the system from such a mode.
BIOS SETUP PNP/PCI Configurations This option configures the PCI bus system. All PCI bus systems on the system use INT#, thus all installed PCI cards must be set to this value.
BIOS SETUP PC Health Status This section shows the parameters in determining the PC Health Status. These parameters include temperatures, fan speeds and voltages. Phoenix - AwardBIOS CMOS Setup Utility PC Health Status CPU Warning Temperature Shutdown Temperature System Temp.

APPENDIX Appendix A. I/O Port Address Map Each peripheral device in the system is assigned a set of I/O port addresses which also becomes the identity of the device. The following table lists the I/O port addresses used.
APPENDIX B. Interrupt Request Lines (IRQ) Peripheral devices use interrupt request lines to notify CPU for the service required. The following table shows the IRQ used by the devices on board.
APPENDIX C. Watchdog Timer Configuration The WDT is used to generate a variety of output signals after a user programmable count. The WDT is suitable for use in the prevention of system lock-up, such as when software becomes trapped in a deadlock. Under these sort of circumstances, the timer will count to zero and the selected outputs will be driven. Under normal circumstance, the user will restart the WDT at regular intervals before the timer counts to zero.
