Setting 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. 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.
Safety precautions Warning! Always completely disconnect the power cord from your chassis whenever you are working on it. Do not make connections while the power is on because sensitive electronic components can be damaged by the sudden rush of power. 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.
Installing DRAM (SIMMs) The PCM-4894 CPU card provides two 72-pin SIMM (Single Inline Memory Module) sockets and supports between 4MB and 64MB. When installing SIMMs, make sure that Bank 1 is filled first. Installing SIMMs Note: that the modules can only fit into a socket one way. 1. Insert the memory module into the socket at a moderate angle. 2.
Ethernet connector (CN1) The Ethernet connects to the PCM-4894 via an adapter cable to a 10-pin polarized header (CN1). For 10Base-T RJ-45 operation, an adapter cable converting CN1 into a standard RJ-45 jack is required.

CHAPTER 3 Award BIOS Setup This chapter describes how to configure the BIOS for the PCM-4894.
System test and initialization These routines test and initialize board hardware. If the routines encounter an error during the tests, you will either hear a few short beeps or see an error message on the screen. There are two kinds of errors: fatal and nonfatal. The system can usually continue the boot up sequence with nonfatal errors.
Award BIOS setup Entering setup Power on the computer and press immediately. This will allow you to enter the utility and the utility screen should appear (below). Setup Utility Initial Screen Award’s BIOS ROM has a built-in setup utility that allows users to modify the basic system configuration. This type of information is stored in a battery-backed CMOS RAM so that the information is retained when the power is turned off.
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. CMOS setup screen Date and Time Configuration Select the Date and Time in the Standard setup. The current values for each category are displayed.
LCD & CRT In the display selection item, you can use PageUp/PageDown key to select Both , LCD, CRT or Auto. Pannel: This selection item allow user to select LCD BIOS to match the LCD types.
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. BIOS features setup Virus Warning When this item is enabled, the Award BIOS will monitor the boot sector and partition table of the hard disk drive for any modification attempts. If an attempt is made, the BIOS will halt the system and the following error message will appear.
CPU Internal Cache/External Cache These two categories, if enabled, can speed up memory access. However, it depends on the CPU/chipset design. Quick Power On Self Test This category speeds up Power On Self Test (POST) after you power up the computer. If it is set to Enabled, BIOS will shorten or skip some check items during POST. Boot Sequence This category determines which drive to search first for the operating system.
Gate A20 Option This entry allows you to select how gate A20 is handled. Gate A20 is a device used to address memory above 1 MB. Initially, gate A20 was handled via a pin on the keyboard. Today keyboards still provide this support, however it is more common and much faster for the system chipset to provide support for gate A20. The choices are thus: Normal and Fast. Security Option This category allows you to limit access to the system.
CHIPSET 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. CHIPSET features setup 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 DRAM and the external cache.
Power management setup By choosing the POWER MANAGEMENT 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. Power management setup Power Management Power management lets you set up your computer to save electricity when it is not actively in use by putting the system into progressively greater power saving modes.
There are four selections for Power Management (PM): Disabled Turns off PM Max Saving Maximized power saving by activating maximum power saving settings after one minute of system inactivity. Min Saving Produces less power saving by activating moderate power saving settings after one hour of system inactivity. User Defined You set the power saving options manually. With the exception of Disabled, three of the above selections have "fixed-mode" settings.
Video Off Method This governs monitor power saving by controlling how power management blanks the monitor screen. The default setting blanks the screen and turns off vertical and horizontal scanning and requires a monitor with "green" features. If you don't have this type of monitor, use the Blank option. DPMS (Display Power Management System) allows the BIOS to control the video display card if the card has the DPMS feature.
Standby Mode This sets the period of system inactivity after which the system goes into Standby mode, the intermediate power saving state. The settings range from 10 seconds to 1 hour and can be set manually when power management is in User Define mode. The default setting is Disabled. When the system goes into power saving mode, power management will skip to the next mode in the sequence if this is disabled.
PM Events PM events are I/O events whose occurrence can prevent the system from entering a power saving mode or can awaken the system from such a mode. In effect, the system remains alert for anything which occurs to a device which is configured as Enabled, even when the system is in a power down mode. When an I/O device wants to gain the attention of the operating system, it signals this by causing an IRQ (Interrupt Request) to occur.
PCI configuration setup By choosing the 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. PCI configuration setup This section describes configuring the Peripheral Component Interconnect (PCI) bus system which allows I/O devices to operate at speeds nearing the speed of the CPU when communicating with its own special components.
Reset Configuration Data This item allows you to reset the configuration data. PCI IRQ Activated By This sets the method by which the PCI bus recognizes that an IRQ service is being requested by a device. Under all circumstances, you should retain the default configuration unless advised by your system manufacturer. The choices are Level/Edge. PCI IDE IRQ Map To This allows you to configure your system to the type of IDE disk controller in use. The more apparent difference is the type of slot being used.
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-4894 on.
