Static Electricity Precaution
After removing the mainboard from its original packing, only place it on a grounded, anti­static surface component side up. Immediately inspect the board for damage. Due to shifting during shipping, it is suggested that the installer press down on all of the socket IC’s to ensure they are properly seated. Do this only with the board placed on a firm flat surface.
During configuration and installation, touch a grounded surface frequently to discharge any static electrical charge that may have built up in your body. The best precaution is to wear a grounded wrist strap. When handling the mainboard or an adapter card avoid touching its components. Handle the mainboard and adapter cards either by the edges or by the adaptercard’s case mounting bracket.

3 Installation Preview
Before you install the KR630 mainboard into the system chassis you may find it convenient to first configure the mainboard hardware. This section describes how to configure the jumper settings, install memory modules, and how to attach the various system components. Before using your computer you must review the following 7 steps:
1. Jumper settings
2. Installation of DRAM modules (DIMM)
3. Installation of the Slot1 Retention Module, Installation of the CPU SEC (Single Edge
Contact) Cartridge
4. Installation of expansion cards
5. Installation of IDE, I/O cables connection., and Power connection
6. Installation of the Power Core to the System.
7. Setup of the system BIOS software
3.1 Jumper Settings
You can configure the hardware options by setting jumpers on the mainboard. A jumper is a set of two or more metal pins in a plastic base attached to the mainboard. A plastic “jumper cap” with a metal (conductive) plate inside fits over two pins to create an electrical contact or short between them. This contact establishes a hardware setting and is referred to as a “closed” jumper setting.
Some jumpers have two pins while others may have three or more. Jumpers are sometimes combined to sets called jumper blocks where all the jumpers in the block must be set together to establish a hardware setting. In this manual, the jumper settings will be described graphically using a triangle (s) always marking pin 1. Those jumpers with two pins will be shown as closed or open. A jumper is closed by placing the plastic jumper cap over the two jumper pins and is opened by removing the jumper cap. Some jumpers are oriented vertically and others horizontally with pin 1 marked as (s=P1)

3.1.4 Processor Speed setting(JP4)
The processor speed depends upon the frequency of the CLOCK GENERATOR which is determined by jumpers. These jumpers tell the system what speed to run at. Currently, this mainboard speed range is from 233MHz to 366MHZ. The CPU input frequency must match the frequency of CLOCK GEN or it will cause the system to malfunction.

3.2.3 Installation Procedure for DIMM
Insert DIMM into the DIMM sockets at a 90 degree angle
.
1) Pin 1 of the DIMM must match with pin 1 of the DIMM socket.
2) The module will only insert into the socket one way. An orientation cut-out will
prevent you from inserting it the wrong way.
3) Insert the DIMM into the DIMM socket at a 90 degree angle. If pin 1 of the DIMM does not line up with pin 1 of the socket, the DIMM will not insert into the socket. After inserting the DIMM module completely into the socket, push the DIMM module into a vertical position.
4) The module should click into place with the retaining clips at each end of the socket snapping behind the module to secure it
5) To release the memory module push both retaining clips outwards and carefully rock the module forward.

4 BIOS Setup
The KR630 mainboard uses an Award BIOS, which is stored in a Flash EEPROM and which can be upgraded using a floppy disk-based program. The BIOS has a built-in Setup program that allows users to modify the basic system configuration setting. The settings are then stored in a dedicated batter-backed memory, called CMOS RAM, that retains the information when the power is turned off. The BIOS provides critical low-level support for the system central processing, memory, and I/O subsystems. The Award BIOS has been customized by adding important, but nonstandard, features such as virus and password protection, power management, and detailed fine-tuning of the chipset controlling the system. The rest of this manual is intended to guide you through the process of configuring your system using Setup.
4.1 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 the of the data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands control of system operations to it.
To start Setup, press the <Del> key some time before or while a message similar to this appears briefly at the bottom of the screen during POST:
Press DEL to enter SETUP
If the message disappears before you respond and you still wish to enter Setup, reboot the system to try again by turning the system OFF then ON or pressing the “RESET” button on the system case. You may also restart by simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys. If you do not press the keys at the correct time and the system does not reboot, an error message will be displayed at the bottom of the screen and you will again be asked to,
Press F1 to continue, DEL to enter SETUP

4.1.2 Getting Help
Press F1 to pop up a small help window that describes the appropriate keys to use and the possible selections for the highlighted item. To exit the Help Window press Esc or the F1 key again.
4.1.3 In Case of Problems
If after making and saving system changes with Setup, you discover that your computer no longer is able to boot, the Award BIOS supports an override to the CMOS settings that resets your system to its default configuration.
You can invoke this override by immediately pressing Insert; when you restart your computer You can restart by either using the ON/OFF switch, the RESET button or by pressing Ctrl­Alt-Delete.
The best advice is to alter only settings that you thoroughly understand. In particular, do not change settings in the Chipset screen without a good reason. The Chipset defaults have been carefully chosen by Award or your system manufacturer for the best performance and reliability. Even a seemingly small change to the Chipset setup may causing the system to become unstable.

4.2 Main Setup Menu
When you enter the Award BIOS CMOS Setup Utility, a Main Menu (Figure 1) appears on the screen. The Main Menu allows you to select from several Setup functions and two exit choices. Use the arrow keys to select among the items and press Enter to accept and enter the sub-menu.

4.3.1 Date
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). Press the PgUp or PgDn key to increment the setting, or type the desired value into the field.
4.3.2 Time
The time format is based on the 24-hour military-time clock. For example, 1 p.m. is 13:00:00. Press the left or right arrow key to move to the desired field. Press the PgUp or PgDn key to increment the setting, or type the desired value into the field.
4.3.3 Hard Disks
The BIOS supports up to four IDE drives. This section does not show information about ther IDE devices, such as a CD-ROM drive, or about other hard drive types, such as SCSI drives. NOTE: We recommend that you select type AUTO for all drives.
The BIOS can automatically detect the specifications and optimal operating mode of almost ll IDE hard drives. When you select type AUTO for a hard drive, the BIOS detects its specifications during POST, every time the system boots.
4-4
If you do not want to select drive type AUTO, other methods of 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. Each defined drive type has a specified number of cylinders, number of heads, write precompensation factor, landing zone, and number of sectors, Drives whose specifications do not accommodate any pre-defined type are classified as type USER.
• Size: Disk drive capacity (approximate). Note that this size is usually slightly greater than the size of a formatted disk given by a disk-checking program.
• Cyls: Number of cylinders
• Head: Number of herds
• Precomp: Write precompensation cylinder
• Landz: Landing zone
• Sector: Number of sectors
• Mode: Auto, Normal, large, or LBA
• Auto: The BIOS automatically determines the optimal mode.
• Normal: Maximum number of cylinders, heads, and sectors supported are 1024, 16,
and 63.
• Large: For drives that do not support LBA and have more than 1024 cylinders.
• 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.

2.88M, 3.5 in 3-1/2 inch double-sided drive; 2.88 megabyte capacity
4.3.5 Video
Select the type of primary video subsystem in your computer. The BIOS usually detects the correct video type automatically. The BIOS supports a secondary video subsystem, but you do not select it in Setup.
EGA/VGA CGA 40 Color Graphics Adapter, power up in 40 column mode.
CGA 80 Color Graphics Adapter, power up in 80 column mode. MONO Monochrome adapter, includes high resolution monochrome adapters.
Enhanced Graphics Adapter/Video Graphics Array. For EGA, VGA, SEGA, SVGA or PGA monitor adapters.
4.3.6 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. All, But Keyboard All, But Diskette POST does not stop for diskette drive errors, but stops for all

other errors.
4.3.7 Memory
You cannot change any values in the Memory fields; they are only for your information. The fields show the total installed random access memory (RAM) and amounts allocated to base memory, extended memory, and other (high) memory, RAM is counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB: approximately one million bytes).
4-6
RAM is the computer’s working memory, where the computer stores programs and data currently being used, so they are accessible to the CPU. Modern personal computers may contain up to 64MB, 128MB, or more.
Base Memory
Typically 640 KB. Also called conventional memory. The DOS operating system and conventional applications use this area.
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-stay­resident (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
Total memory
System total memory is the sum of base memory, extended memory, and other memory.

4.4.2 CPU Level 1/Level 2 Cache
Cache memory is additional memory that is much faster than conventional DRAM (system memory). Pentium II CPU has Level 1 and Level 2 build-in cache. These fields allow you to Enabled (Default) or Disabled to turn on or turn off the memory cache ability.
4.4.3 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 10 different boot sequence
4-8
options of three drives each. In addition to the traditional drives A and C, options include IDE hard drives D,E, and F; plus a SCSI hard drive and a CD-ROM drive.
4.4.4 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.
4.4.5 Boot Up Floppy Seek
When Enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KN< 1.2MB, and 1.44MB capacity all have 80 tracks. Because very few modern PCs have 40-track floppy drives, we recommend that you set this field to Disabled to save time.
4.4.6 Boot Up NumLock Status
Toggle between On or off to control the state of the NumLock key when the system boots. When toggled On, the numeric keypad generates numbers instead of controlling cursor operations.
4.4.7 Typematic Rate Setting
When Disabled, the following two items (Typematic Rate and Typematic Delay) are irrelevant. Keystrokes repeat at a rate determined by the keyboard controller in your system. When Enabled, you can select a typematic a\rate and typematic delay.
4.4.8 Typematic Rate (Chars/Sec)
When the typematic rate setting is enabled, you can select a typematic rate (the rate at which character repeats when you hold down a key) of 6,8,10,12,15,20,24, or 30 characters per second.
4.4.9 Typematic Delay (Msec)
When the typematic rate setting is enabled, you can select a typematic delay (the delay before key strokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.
4.4.10 Security Option
If you have set a password, select whether the password is required every time the System boots, or only when you enter Setup.
4-9
4.4.11 PCI/VGA Palette Snoop
Some display cards that are not standard VGA such as graphics accelerators or MPEG cards may not show the correct colors, the setting can correct this problem once you set it to Enable, To default setting leave at Disabled.
4.4.12 OS select for DRAM>64MB
Select OS2 only if you are running OS/2 operating system with greater than 64MB of RAM on your system.
4.4.13 Shadow
Software that resides in a read-only memory (ROM) chip on a device is called firmware. The Award BIOS 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 adapter.
Shadowing copies firmware from ROM into system RAM, where the CPU can read it through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by the system through the 8-bit x-bus. Shadowing improves the performance of the system BIOS and similar ROM firmware for expansion peripherals, but it also reduces the amount of high memory (640KB to 1 MB) available for loading device drivers, etc.
Enable shadowing into each section of memory separately. Many system designers hardwire shadowing of the system BIOS and eliminate a System BIOS Shadow option.
Video BIOS shadows into memory area C0000-C7FFF> The remaining areas shown on the BIOS Features Setup screen may be occupied by other expansion card firmware. If an expansion peripheral in your system contains ROM-based firmware, you need to know the address range the ROM occupies to shadow it into the correct area of RAM.

4.5.2 DRAM Speed Selection
The value in this field must correspond to the speed of the DRAM installed in your system. DO NOT change the default setting of this fields, as determined by the system board manufacturer for the installed DRAM. This value is access speed, so a lower value means a faster system.
4.5.3 DRAM ECC/Parity Select
Select Parity, ECC, or Disabled, depending on the type of DRAM installed in your system. Also you need install Pentium II CPU cartridge with ECC support for ECC function properly once you installed 36-bit SIMM.
4.5.4 System BIOS Cacheable
Select Enabled allows caching of the system BIOS ROM at F000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result.
4.5.5 Video BIOS Cacheable

4.5.6 8 Bit I/O Recovery Time
The recovery time is the length of time, measured in CPU clocks, which the system will delay after the completion of an input/output request. This delay takes place because the CPU is operating so much faster than the input/output bus that the CPU must be delayed to allow for the completion of the I/O. This item allows you to determine the recovery time allowed for 8 bit I/O. Choices are from NA, 1 to 8 CPU clocks.
4.5.7 16 Bit I/O Recovery Time
This item allows you to determine the recovery time allowed for 16 bit I/O. Choices are from NA, 1 to 4 CPU clocks.
4.5.8 Memory Hole At 15M-16M
In order to improve performance, certain space in memory can be reserved for ISA cards. This memory must be mapped into the memory space below 16 MB. You can reserve this area of system memory for ISA adapter ROM. When that area is reserved it cannot be cached. The user information of peripherals that need to use this area of system memory usually discusses their memory requirements.
4.5.9 Passive Release
When Enabled, CPU to PCI bus accesses are allowed during passive release. Otherwise, the arbiter only accepts another PCI master access to local DRAM.
4.5.10 Delayed Transaction
The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select Enabled to support compliance with PCI specification version 2.1.

If your system does not have one or two PCI IDE connectors on the system board, select values according to the type of IDE interface(s) installed in your system (PCI or ISA). Standard ISA interrupts for IDE channels are IRQ14 for primary and IRQ15 for secondary.
4.7.8 Primary/Secondary IDE INT#
Each PCI peripheral connection is capable of activating up to four interrupts: INT$ A, INT# B, INT# C and INT#D. By default, a PCI connection s assigned INT3 A. Assigning INT#B has no meaning unless the peripheral device requires two interrupt services rather than just one. Because the PCI IDE interface in the chipset has two channels, it requires two interrupt services. The primary and secondary IDE INT# fields default to values appropriate for two PCI IDE channels, with the primary PCI IDE channel having a lower interrupt than the secondary.

4.8.1 IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or multiple sector read/write. If your IDE hard drive supports block mode (most new drives do), select Enabled for automatic detection of the optimal number of block read/writes per sector the drive can support.
4.8.2 On-Chip Primary/Secondary PCI IDE
The integrated peripheral controller contains an IDE interface with support for two IDE CHANNELS. Select Enabled to activate each channel separately.
4.8.3 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.
4.8.4 Onboard Serial Port 1/2
Select an address and corresponding interrupt for the first and second serial ports.
