KR7A-133/KR7A- 133R Motherboard Placement
The Figure 1 shows the KR7A-133/KR7A-133R layout diagram. We show all major components on this diagram for your reference.
Figure 1. KR7A-133/KR7A-133R Layout Diagram As above !, " and # are only shown on the KR7A-133R motherboard. ! is a RAID controller and " and # are connectors for two IDE channels. The motherboard is enclosed in a transparent anti-static box, and you must take it out carefully. The motherboard has many sensitive electronic components that can be damaged by static electricity. After you check all box contents and unpack the motherboard from the box, you can install the processor onto the motherboard.
Installing the Processor:
Note: " Installing a heatsink and cooling fan is necessary for heat to dissipate from your processor. Failing to install these items may result in overheating and processor damage. " The AMD Socket A processor will produce a lot of heat while operating, so you need to use a large heat sink that is specially designed for the AMD socket A processor. Otherwise, it may result in overheating and processor damage. " Until your processor fan and its power cable are installed properly, never plug the ATX power cable into the motherboard. This can prevent possible processor damage. " Please refer to your processor installation manual or other documentation with your processor for detailed installation instructions. The AMD Socket A Athlon XP, Athlon and Duron processor installation is easy, like Socket 7 Pentium processors before. Because it uses the Socket A ZIF (Zero Insertion Force) socket, you can easily fix the processor firmly into position. Figure 2 shows you what the socket A looks like, and how to raise the lever. The Socket A has more pins than the socket 7. Therefore, a Pentium level processor cannot be inserted into a socket A. If you put it in the wrong direction, you will not be able to insert the processor easily, and processor pins will not fully go into the socket. If this is the case, please change the direction, until it easily and fully inserts into the socket A. See Figure 3. At the same time, check the processor temperature detection thermistor height (if your motherboard has this component). Then, you can slowly insert the processor into the Socket A.
Heatsink Installation Hints:
The proper procedure to install the heatsink kit: First, install the processor into the processor socket. Insert the heatsink left side fix plate into the processor socket left side fix hooks. Make sure the fit is very tight. Check the photo on the left.
Insert a flat screwdriver into the middle slot of the right side fix plate and push down. Next, push the fix plate over the socket hooks on the right side. Check the photo on the left.
Check the photo on the left. You have finished the heatsink installation. Now hold the whole heatsink and slightly shake it, make sure the bottom right side of the heaksink does not contact the right side of the Socket (see bottom picture). Otherwise, the processor die does not have proper contact with the heatsink. This situation may cause processor damage. Remember to install the heatsink fan power cable to the CPU fan header on the motherboard. Now you can reinstall the motherboard back into the chassis.

When all of the above procedures done, you can connect the ATX power cable to the motherboard. If you have a different type of heatsink kit, please refer to the manual that came with the heatsink kit. The left photo shows another type of heatsink fix plate design. The install sequence is still the same, from right side to left side. Just remember that. We strongly recommend that you to buy a heatsink equipped with three holes in the fix plate. This will provide the best stability and will prevent the Socket fix hooks to become broken or damaged. The left photo shows the bottom right side of the heaksink in contact with the right side of the Socket. In this situation, the processor die does not properly contact the heatsink. If you start the computer at this monent, it will immediately cause processor damage. Always check this location when you finish the heatsink installation.
Install the Motherboard into the Chassis
After you install the processor onto the motherboard, you can start to fix the motherboard into the chassis. First, you need to fix the motherboard onto the chassis. Most computer chassis will have a base on which there will be many mounting holes that allow the motherboard to be securely attached, and at the same time, prevent short circuits. Use studs or spacers attached in the chassis to fix the motherboard.

Installing System Memory

This motherboard provides four 184-pin DDR DIMM slots memory
expansion. The minimum memory is 64 MB and the maximum memory is 3 GB (Unbuffered) or 4 GB (Registered) DDR SDRAM. There are four memory module sockets on the board (for a total of eight banks). Insert the DDR DIMM module into the expansion socket as shown in the illustration. Note how the module is keyed to the socket. You can refer to Figure 4 for the details. This ensures that there is only one way to plug in the DDR DIMM module. Firmly press the DDR DIMM module into DDR DIMM socket; making certain the module is completely seated in the DDR DIMM socket. Next, you need to connect all necessary device cables to the concerning headers and connectors on the motherboard in order to finish the hardware installation of your system.

2-1. Installation of the AMD Athlon XP, Athlon and Duron CPU
Note ! Installing a heatsink and cooling fan is necessary for heat to dissipate from your processor. Failing to install these items may result in overheating and processor damage. ! The AMD Socket A processor will produce a lot of heat while operating, so you need to use a large heat sink that is especially designed for the AMD socket A processor. Otherwise, it may result in overheating and processor damage. ! If your processor fan and its power cable are not installed properly, never plug the ATX power cable into the motherboard. This can prevent possible processor damage. ! Please refer to your processor installation manual or other documentation with your processor for detailed installation instructions. The AMD Socket A Athlon XP, Athlon and Duron processor installation is easy, like Socket 7 Pentium processors before. Because it uses the Socket A ZIF (Zero Insertion Force) socket, you can easily fix the processor firmly into position. Figure 2-1 shows you what the socket A looks like, and how to open the lever. The socket A has more pins than the socket 7. Therefore, a Pentium level processor cannot be inserted into a socket A.

(9). SPDIF1 Header: Sony/Philips Digital InterFace Output Header (Optional) This header is for SPDIF output signal use. This option can let you output the digital SPDIF signal to the external decode equipment. This function is optional.
(10). JP8 Header: Processor FSB Frequency Setting Header Jumper JP8 used to select processor FSB frequency. The default setting is 100 MHz (pin 2 and 3 shorted). Please accord your processor FSB speed to set correct FSB frequency.
(11). CD1 and AUX1 Headers: CD Audio and Auxiliary audio signal input headers These connectors connect to the audio output of internal CD-ROM drive or add-on card.
(12). FDC1 Connector This 34-pin connector is called the floppy disk drive connector. You can connect a 360K, 5.25, 1.2M, 5.25, 720K, 3.5, 1.44M, 3.5 or 2.88M, 3.5 floppy disk drive. A floppy disk drive ribbon cable has 34 wires and two connectors to provide the connection of two floppy disk drives. After connecting the single end to the FDD1, connect the two connectors on the other end to the floppy disk drives. In general, people only install one floppy disk drive on their computer system.
Note A red mark on a wire typically designates the location of pin 1. You need to align the wire pin 1 to the FDC1 connector pin 1, then insert the wire connector into the FDC1 connector.
(13). IDE1and IDE2 Connectors This motherboard provides two IDE ports (IDE1 & IDE2) to connect up to four IDE devices in Ultra DMA 100 mode by Ultra DMA 66 ribbon cables. Each cable has 40-pin 80-conductor and three connectors, providing two hard drive connections with the motherboard. Connect the single end (blue connector) at the longer length of ribbon cable to the IDE port on motherboard, and the other two ends (gray and black connector) at the shorter length of the ribbon cable to the connectors on hard drives. If you want to connect two hard drives together through one IDE channel, you must configure the second drive to Slave mode after the first Master drive. Please refer to the HDD documentation for jumper settings. The first drive connected to IDE1 is usually referred to as Primary Master, and the second drive as Primary Slave. The first drive connected to IDE2 is referred to as Secondary Master and the second drive as Secondary Slave. Keep away from connecting one legacy slow speed device, like CD-ROM, together with another hard disk drive on the same IDE channel; this will decrease your integral system performance.

Figure 2-8. Ultra DMA 66 Ribbon Cable Outline
Note ! The Master or Slave status of the hard disk drive is set on the hard disk itself. Please refer to the hard disk drive users manual. ! To connect Ultra DMA 100 devices on IDE1and IDE2, an Ultra DMA 66 cable is required. ! A red mark on a wire typically designates the location of pin 1. You need to align the wire pin 1 to the IDE connector pin 1, before inserting the wire connector into the IDE connector.
Figure 2-9. NV7m back panel connectors Figure 2-9 shows the NV7m back panel connectors, these connectors are for connection to outside devices to the motherboard. We will describe which devices will attach to these connectors below. (14). PS/2 Keyboard Connector Attach a PS/2 keyboard connector to this 6-pin Din-connector. If you use an AT keyboard, you can go to a computer store to purchase an AT to ATX converter adapter, then you can connect your AT keyboard to this connector. We suggest you use a PS/2 keyboard for best compatibility.
(15). PS/2 Mouse Connector Attach a PS/2 mouse to this 6-pin Din-connector.
(16). Serial Port COM1 Connector This motherboard provides one COM port, you can connect an external modem, mouse or other devices that support this communication protocol to these connectors. You can decide which external devices you want to connect to COM1. The COM port can only have one device connected at a time. (17). VGA Port VGA1 Connector This motherboard had built-in the nVIDIA 256-bit 3D/2D graphic accelerator, so you dont need to buy another AGP grapgic accelerator. This DIN 15 pin Female connector is for a VGA output signal to the monitor or LCD display. You can connect the plug from the monitor to this connector. If you don't move your system often, we suggest you fasten the two screws from the plug with this connector. It will assure the quality of your display.
(18). Parallel Port Connector This parallel port is also called an LPT port, because it usually connects to the printer. You can connect other devices that support this communication protocol, like an EPP/ECP scanner, etc.
(19). USB Port Connectors This motherboard provides two USB ports. Attach the USB connector from the individual device to these connectors. You can attach USB devices such as a, scanner, digital speakers, monitor, mouse, keyboard, hub, digital camera, joystick etc. to one of each USB connector.

Figure 3-1. CMOS Setup Utility Screen Shot Users Manual

Chapter 3

In the BIOS Setup main menu of Figure 3-1, you can see several options. We will explain these options step by step in the following pages of this chapter, but let us first see a short description of the function keys you may use here: ! ! ! ! Press Esc to quit the BIOS Setup. Press (up, down, left, right) to choose, in the main menu, the option you want to confirm or to modify. Press F10 when you have completed the setup of BIOS parameters to save these parameters and to exit the BIOS Setup menu. Press Page Up/Page Down or +/- keys when you want to modify the BIOS parameters for the active option.
Note You only can use the awdflash.exe attached in NV7m product CD-ROM, DO NOT USE the others Award flash program to flash your NV7m BIOS. Note Parts of the screenshot may not same as you see on your screen, because the BIOS version may change periodically. However, most of the functions covered in this manual will work. We suggest that you go to our WEB site often to see if there are new manual releases. Then you can check the newly updated BIOS items. Computer Knowledge: CMOS Data Maybe you have heard somebody saying that his or her CMOS DATA was lost. What is the CMOS? Is it important? The CMOS is the memory used to store the BIOS parameters that you have configured. This memory is passive. You can read its data, and you can also store data in it. But this memory has to be powered by a battery, in order to avoid any loss of its data when the computer is turned off. Since you may have to change the CMOS battery when it is out of power and if doing so, you will loose all CMOS data, therefore, we recommend that you write down all the parameters of your hardware, or to put a label with these parameters on your hard disk.
3-1. Standard CMOS Features Setup Menu
This contains the basic configuration parameters of the BIOS. These parameters include date, hour, VGA card, floppy disk and HDD settings.
Figure 3-2A. Standard CMOS Features Screen Shot Date (mm:dd:yy): You can set the date in this item: month (mm), date (dd) and year (yy). Time (hh:mm:ss): You can set the time in this item: hour (hh), minute (mm) and second (ss).
IDE Primary Master / Slave and IDE Secondary Master / Slave:

These items have a sub-menu to let you choose further options. You can refer to figure 3-3B to check what options are available.
Figure 3-2B. IDE Primary Master Screen Shot Users Manual
IDE HDD Auto-Detection: Press the Enter key for the BIOS to auto detect all detailed parameters of the hard disk drivers (HDD). If auto detection is successful, the correct values will be shown in the remaining items of this menu. Note ( A new IDE HDD must be first formatted, otherwise it cant do the read/write. The basic step in using a HDD is to run FDISK, and then FORMAT the drive. Most current HDDs have already been subjected to low-level format at the factory, so you can probably skip this operation. Remember though, the primary IDE HDD must have its partition set to active within the FDISK procedure. ) If you are using an old HDD that is already formatted, auto detection cant detect the correct parameters. You may need to do a low-level format or set the parameters manually, and then check if the HDD is working. IDE Primary Master: Three settings are available: None * Auto * Manual, The default setting is Auto. If you choose Auto, the BIOS will automatically check what kind hard disk you are using. If you want to set the HDD parameters yourself, make sure you fully understand the meaning of the parameters, and be sure to refer to the manual provided by the HDD manufacture to get the settings right. Access Mode: Since old operating systems were only able to support HDDs with capacities no bigger than 528MB, any hard disk with more than 528MB was unusable. AWARD BIOS features a solution to this problem: you can, according to your operating system, choose four operating modes: CHS * LBA * Large *Auto. The HDD auto detection option in the sub-menu will automatically detect the parameters of your hard disk and the mode supported.

! CHS (Normal mode):

Standard normal mode supports hard disks of up to 528MB or less. This mode directly uses positions indicated by Cylinders (CYLS), Heads, and Sectors to access data.
! LBA (Logical Block Addressing) mode:
The earlier LBA mode can support HDD capacities of up to 8.4GB, and this mode uses a different method to calculate the position of disk data to be accessed. It translates Cylinders (CYLS), Heads and Sectors into a logical address where data is located. The Cylinders, Heads, and Sectors displayed in this menu do not reflect the actual structure of the hard disk, they are just reference values used to calculate actual positions. Currently, all high capacity hard disks support this mode, thats why we recommend you use this mode. Currently, the BIOS can support the INT 13h extension function, enabling the LBA mode to support hard disk drive capacities exceeding 8.4GB.

! Large Mode:

When the number of cylinders (CYLs) of the hard disk exceeds 1024 and DOS is not able to support it, or if your operating system does not support LBA mode, you should select this mode.

!SYSTEM: When you choose System, a password is required each time the computer boots up. If the correct password is not given, the system will not start. To disable security, select Set Supervisor Password at main menu and then you will be asked to enter password. Do not type anything and just press the Enter key and it will disable security. Once security is disabled, the system will boot and you can enter the BIOS setup menu freely. Notice Dont forget your password. If you forget the password, you will have to open the computer case and clear all information in the CMOS before you can start up the system. But by doing this, you will have to reset all previously set options.
3-3. Advanced Chipset Features Setup Menu
The Chipset Features Setup Menu is used to modify the contents of the buffers in the chipset on the motherboard. Since the parameters of the buffers are closely related to hardware, if the setup is not correct or is false, the motherboard will become unstable or you will not be able to boot up. If you dont know the hardware very well, use default values (i.e. use the LOAD SETUP DEFAULTS option).
Figure 3-4. Advanced Chipset Features Screen Shot
You can use the arrow keys to move between the items. Use PgUP, PgDn, + or - key to change the values. When you have finished setting up the chipset, press ESC to go back to the main menu. Note The parameters in this screen are for system designers, service personnel, and technically competent users only. Do not reset these values unless you understand the consequences of your changes. AGP Aperture Size: Five options are available: 32MB ! 64MB ! 128MB ! 256MB ! 512MB !Back to 32MB. The default setting is 64MB. This option specifies the amount of system memory that can be used by the AGP device. 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. See http://www.agpforum.org for AGP information. Frame Buffer Size: Four options are available: 8MB ! 16MB ! 32MB ! Disabled !Back to 8MB. The default setting is 32MB. This item can let you select the frame buffer memory size for onboard VGA accelerator. Memory Timings: Two options are available: Aggressive ! Optimal. The default setting is Optimal. Choose Aggressive for better memory performance, choose Optimal for better memory compability. CAS Latency Override: Three options are available: 2 Clocks ! 2.5 Clocks ! Auto.

ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The ACPI functions are always Enabled. If you want ACPI functions to work normally, you should notice two things. One is your operating system must support ACPI, as of now only Microsoft Windows 98 SE and Windows 2000 supports these functions. The second thing is that all devices and add-on cards in your system must fully support ACPI, both hardware and software (drivers). If you want to know if your devices or add-on cards support ACPI or not, please contact the device or add-on card manufacture for more information. If you want to know more about ACPI specifications, please go to the address below for more detailed information: http://www.teleport.com/~acpi/acpihtml/home.htm Note: If you enable the ACPI function in the BIOS setup, the SMI function will not work. ACPI requires an ACPI-aware operating system. ACPI features include: ! Plug and Play (including bus and device enumeration) and APM functionality normally contained in the BIOS. ! Power management control of individual devices, add-in cards (some add-in cards may require an ACPI-aware driver), video displays, and hard disk drives. ! A Soft-off feature that enables the operating system to power off the computer. ! Support for multiple wake-up events (see Table 3-5-1). ! Support for a front panel power and sleep mode switch. Table 3-5-2 describes the system states based on how long the power switch is pressed, depending on how ACPI is configured with an ACPI-aware operating system. Note If you enable the ACPI function in the BIOS setup, the SMI switch function will not work. System States and Power States Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state. The table below describes which devices or specific events can wake the computer from specific states.
Table 3-5-1: Wake Up Device and Events These device/events can wake up the computer Power switch RTC alarm LAN Modem IR command USB PS/2 keyboard PS/2 mouse from this state Sleeping mode or power off mode Sleeping mode Sleeping mode Sleeping mode Sleeping mode Sleeping mode Sleeping mode Sleeping mode
Table 3-5-2: Effect of Pressing the Power Switch If the system is in this state Off On On Sleep ACPI Suspend Type: Three options are available: S1 (POS) * S3 (STR) * S1&S3. The default setting is S3 (STR). POS is PowerOn-Suspend, and STR is Suspend-To-RAM. Generally, ACPI has six states: System S0 state, S1 state, S2 state, S3 state, S4 state, S5 state. S1 and S3 states are described below: The S1 (POS) State (POS means Power On Suspend): While the system is in the S1 sleeping state, its behavior is as described below: ! The processor is not executing instructions. The processors complex context is maintained. ! Dynamic RAM context is maintained. ! Power Resources are in a state compatible with the system S1 state. All Power Resources that supply a System Level reference of S0 are in the OFF state. ! Devices states are compatible with the current Power Resource states. Only devices which solely reference Power Resources which are in the ON state for a given device state can be in that device state. In all other cases, the device is in the D3 (off) state. ! Devices that are enabled to wake the system and that can do so from their current device state can initiate a hardware event which transitions the system state to S0. This transition causes the processor to continue execution where it left off. To transition into the S1 state, the operating software does not have to flush the processor's cache. The S3 (STR) State (STR means Suspend to RAM): The S3 state is logically lower then the S2 state and is assumed to conserve more power. The behavior of this state is defined as follows: ! Processor is not executing instructions. The processor complex context is not maintained. NV7m Motherboard and the power switch is pressed for Less than four seconds More than four seconds Less than four seconds Less than four seconds the system enters this state Power on Soft off/Suspend Fail safe power off Wake up

Introducing the BIOS ! Dynamic RAM context is maintained.
! Power Resources are in a state compatible with the system S3 state. All Power Resources that supply a System Level reference of S0, S1, or S2 are in the OFF state. ! Devices states are compatible with the current Power Resource states. Only devices which solely reference Power Resources which are in the ON state for a given device state can be in that device state. In all other cases, the device is in the D3 (off) state. ! Devices that are enabled to wake the system and that can do so from their current device state can initiate a hardware event which transitions the system state to S0. This transition causes the processor to begin execution at its boot location. The BIOS performs initialization of core functions as required to exit an S3 state and passes control to the firmware resume vector. Please see the ACPI Specification Rev. 1.0 book section 9.3.2 for more details on BIOS initialization. From the software point of view, this state is functionally the same as the S2 state. The operational difference can be that some Power Resources that could be left ON in the S2 state might not be available to the S3 state. As such, additional devices can be required to be in logically lower D0, D1, D2, or D3 state for S3 than S2. Similarly, some device wake events can function in S2 but not S3. Because the processor context can be lost while in the S3 state, the transition to the S3 state requires that the operating software flush all dirty cache to DRAM.

3-6. PnP/PCI Configurations Setup Menu
In this menu, you can change the INT# and IRQ# of the PCI bus and other hardware settings.
Figure 3-7A. PnP/PCI Configurations Screen Shot Users Manual
Force Update ESCD: Two options are available: Disabled or Enabled. The default setting is Disabled. Normally, you should leave this field Disabled. Select Enabled to reset Extended System Configuration Data (ESCD) when you exit Setup if you have installed a new add-on and the system reconfiguration has caused a serious conflict that prevents the operating system from booting. Computer Knowledge: ESCD (Extended System Configuration Data) The ESCD contains the IRQ, DMA, I/O port, memory information of the system. This is a specification and a feature specific to the Plug & Play BIOS. Resources Controlled By: When resources are controlled manually, assign each system interrupt as one of the following types, depending on the type of device using the interrupt: Legacy devices compliant with the original PC AT bus specification require a specific interrupt (such as IRQ4 for serial port 1). PCI PnP devices comply with the Plug and Play standard, whether designed for the PCI or legacy bus architecture. Two options are available: Auto (ESCD) or Manual. The default setting is Auto (ESCD). The Award Plug and Play BIOS has the capability to automatically configure all boot and Plug and Play compatible devices. If you select Auto (ESCD), all of the interrupt request (IRQ) fields become unselectable, as the BIOS automatically assigns them.

3-10. Set Supervisor Password
Can let you enter and change the options of the setup menus.

3-11. Set User Password

Set Password: Can enter but do not have the right to change the options of the setup menus. When you select this function, the following message will appear at the center of the screen to assist you in creating a password. ENTER PASSWORD: Type the password, up to eight characters in length, and press <Enter>. The password typed now will clear any previously entered password from CMOS memory. You will be asked to confirm the password. Type the password again and press <Enter>. You may also press <Esc> to abort the selection and not enter a password. To disable a password, just press <Enter> when you are prompted to enter the password. A message will confirm the password will be disabled. Once the password is disabled, the system will boot and you can enter Setup freely. PASSWORD DISABLED. Users Manual
When a password has been enabled, you will be prompted to enter it every time you try to enter Setup. This prevents an unauthorized person from changing any part of your system configuration. Additionally, when a password is enabled, you can also require the BIOS to request a password every time your system is rebooted. This would prevent unauthorized use of your computer. You determine when the password is required within the BIOS Features Setup Menu and its Security option. If the Security option is set to System, the password will be required both at boot and at entry to Setup. If you set to Setup, prompting only occurs when trying to enter Setup.
3-12. Save & Exit Setup
Pressing <Enter> on this item asks for confirmation: Save to CMOS and EXIT (Y/N)? Y Pressing Y stores the selections made in the menus in CMOS - a special section of memory that stays on after you turn your system off. The next time you boot your computer, the BIOS configures your system according to the Setup selections stored in CMOS. After saving the values the system is restarted again.
3-13. Exit Without Saving
Pressing <Enter> on this item asks for confirmation: Quit without saving (Y/N)? Y This allows you to exit Setup without storing in CMOS any change. The previous selections remain in effect. This exits the Setup utility and restarts your computer.
