The following is a list of typical peripherals required to build a minimum system: " Power supply and passive backplane(optional) " IBM PC/AT keyboard " Display monitor " Floppy or hard disk with MS-DOS or Flash Disk emulator 3.1 Installing the SIMMs You can install from 2MB up to 128 MB memory on board using 1, 2,4,8,16,32 or 64MB 72-pin FPM/EDO SIMMs. ��� Ensure that all power supplies to the system are switched Off. ��� Insert the first SIMM edge connector at a slight angle into the socket of SIMM 1 close to the center of the board. Note that the SIMM is keyed and will only go in one direction. ��� Push the SIMM back into the connector carefully until it snaps into place. ��� Check to make sure the SIMM is inserted securely. ��� Repeat Steps 2-4 for the remaining SIMM in SIMM 2. 3.2 Installing the CPU ��� Match pin one (white dot) on the CPU with pin one of the PGA socket. Note pin one is marked on the board. In addition, the PGA socket has a diagonal corner or may have an arrow marked on the base of the socket denoting the side containing pin one. ��� To complete the installation, gently press the CPU onto place. ��� Double check the insertion and orientation of the CPU before applying power. Improper installation will result in permanent damage to the CPU. 3.3 Completing the Installation To complete the installation, the following steps should be followed: 1. Make sure the power is off. 2. Set the configuration jumpers in accordance with Chapter 2. 3. Install the NEAT-575CPU card into one of the slots in a passive backplane. Or, just take the NEAT-575 alone as a single board computer. 4. Connect the applicable I/O cables and peripherals, i.e. floppy disk, hard disk, monitor, keyboard, power supply and etc. NOTE: the color of pin one is usually red or blue, while others are gray. 5. Turn on the power. Chapter 4 Award’s BIOS Setup Award's BIOS ROM has a built-in Setup program that allows users to modify the basic system configuration.

Memory This category is display-only and determined by POST (Power On Self Test) of the BIOS. Base Memory The POST of the BIOS will determine the amount of base (or conventional) memory installed in the system. The value of the base memory typically is 512K for systems with 512K memory installed on the motherboard, or 640K for systems with 640K or more memory installed on the motherboard. Extended Memory The BIOS determines how much extended memory is exists in the system during the POST. This is the amount of memory located above 1MB in the CPU's memory address map. Other Memory This refers to the memory located in the 640K to 1024K address space. This memory can be used for different applications. DOS uses this area to load device drivers to keep as much base memory free for application programs. Most use of this area is for Shadow RAM. Total Memory System total memory is the sum of basic memory, extended memory and other memory. BIOS Features Setup Menu ROM PCI/ISA BIOS BIOS FEATURES SETUP AWARD SOFTWARE, INC.

During and after the system boots up, any attempt to write to the boot sector or partition table of the hard disk drive will halt the system and the following error message will appear. In the mean time, you can run an anti-virus program to locate the problem. ! WARNING ! Disk boot sector is to be modified Type "Y" to accept write or "N" to abort write Award Software, Inc. Enabled The virus warning activates automatically and will cause warning message, when any attempt to access the boot sector or hard disk partition table during the system’s boot up process. Disabled No warning message appears. Note: Many disk diagnostic programs that attempt to access the boot sector table can cause the above warning message. If you are going to run such a program, we recommend that you disable the Virus Protection beforehand. CPU Internal Cache/External Cache These two categories speed up memory access. However, it depends on CPU/chipset design. The default value is Enable. If your CPU does not have Internal Cache then this item “CPU Internal Cache” will not appear. Enabled Enable cache Disabled Disable cache Quick Power On Self Test This category speeds up Power On Self Test (POST) after you power on the computer. If it is set to Enable, BIOS will shorten or skip some check items during POST. Enabled Enable quick POST Disabled Normal POST Boot Sequence This category determines which drive that the computer searches first for the disk operating system. i.e., DOS. Default value is “C,CDROM,A”. C,CDROM,A System will first search the hard disk drive then CDROM, floppy disk drive. A, C, CDROM System will first search the floppy disk drive then hard disk drive, CDROM Boot Up Floppy Seek During POST, BIOS will determine if the floppy disk drive installed is 40 or 80 tracks. The 360K is 40 tracks, and 720K, 1.2M and 1.44M are all 80 tracks. BIOS searches the floppy disk drive to determine if it is 40 or 80 tracks. Enabled Note that the BIOS can not distinguish the difference among 720K, 1.2M or 1.44M drive type. The BIOS considers as an 80 tracks' disk drives. Disabled BIOS will not search the type of floppy disk drive by track number. Hence there will not be any warning message if the drive installed is 360K. Boot Up NumLock Status The default value is On. On Keypad is number keys Off Keypad is arrow keys Boot Up System Speed It selects the default system speed -- the speed that the system will run immediately after power up process.

This chipset manages bus speeds and access to system memory resources, such as DRAM and the external cache. 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. The default settings have been chosen because they provide the best operating condition for your system. The only time you might consider making any change would be if you discovered data lost while using your system. DRAM settings The first chipset setting deals with CPU access to dynamic random access memory (DRAM). The default timings have been careful chosen, and should be altered if data is losing. Such a scenario might occur if your system had mixed speed DRAM chips installed so that a greater delay may be require to preserve the integrity of the data held in the slower memory chips. Auto Configuration Values are pre-defined for DRAM and cache. The timing is set according to CPU type & system clock. The Choice: Enabled, Disabled. Note: When this item is enabled, the pre-defined items become SHOW- ONLY. DRAM Timing The DRAM timing controlled by the DRAM Timing Register inside the chip. Depend on the system design, appropriate timing will de programmed into the register. A slower rate may be required in certain system designs to support loose layout or slower memory. 60ns DRAM Timing Type. 70ns DRAM Timing Type. DRAM RAS# precharge time DRAM must be refreshed constantly or it will lose its data. Normally, DRAM is refreshed entirely after a single request. This option allows you to determine the number of CPU clock allocated for the Row Address Strobe to accumulate its charge before the DRAM is refreshed. If there is no sufficient time, refresh may be uncompleted and data may lose. 3 Three clocks. 4 Four clocks. DRAM R/W leadoff timing This function sets the number of CPU clocks allowed before reads and writes to DRAM. 7/6 Seven clocks leadoff for reads and six clocks leadoff for writes. 6/5 Six clocks leadoff for reads and five clocks leadoff for writes. Fast RAS# to CAS# delay When DRAM is accessed, both the rows and the columns are addressed separately. This setup item allows you to determine the timing of the transition from Row Address Strobe (RAS) to Column Address Strobe (CAS). 3 Three CPU clock delay. 2 Two CPU clock delay. DRAM Read This function sets the timing for burst mode reads from two different DRAM(EDO/FPM). Burst read and write requests generated by the CPU in four separate parts. The first part provides the location within the DRAM where the read or write takes place while the remaining three parts provide the actual data. The lower the numbers of the timing, the faster the system will address memory. x222/x333 Read DRAM (EDO/FPM) timings are 2-2-2/3-3-3 x333/x444 Read DRAM (EDO/FPM) timings are 3-3-3/4-4-4 x444/x444 Read DRAM (EDO/FPM) timings are 4-4-4/4-4-4 ��� DRAM write burst timing This function sets the timing of burst mode writes to DRAM. Burst read and write requests generated by the CPU in four separate parts. The first part provides the location within the DRAM where the read or write takes place while the remaining three parts provide the actual data. The lower the number of the timing, the faster the system will address memory. x222 Write DRAM timings are 2-2-2-2 x333 Write DRAM timings are 3-3-3-3 x444 Write DRAM timings are 4-4-4-4 Turbo read leadoff The turbo read leadoff may be required in certain system design to support layouts or faster memories. The Choice: Enabled, Disabled. DRAM speculative leadoff The 430HX chipset allows DRAM’s read request to be generated slightly before the address is fully decoded. This can reduce all read latencies. The CPU will issue a read request that includes the place (address) in memory where the desired data to be found. This request is received by the DRAM controller. When the speculative Leadoff is enabled, the DRAM controller will issue a read command slightly before it finishes determining the address. The Choice: Enabled, Disabled. Turn-Around insertion When this is enabled, the chipset will insert one extra clock to the turn- around of back-to-back DRAM cycles. The Choice: Enabled, Disabled. ISA Clock This item allows you to select the ISA clock speed. PCI CLK/3 ISA clock =PCI clock/3 PCI CLK/4 ISA clock =PCI clock/4 Cache Features System BIOS Cacheable When this function is enabled, the BIOS ROM’s addresses at F0000H- FFFFFH will be duplicated into the SRAM. It will work with the cache controller that is enabled. Enabled BIOS access cached Disabled BIOS access not cached ��� Video BIOS Cacheable As with caching the System BIOS above, enabling the Video BIOS cache will cause access to video BIOS addressed at C0000H to C7FFFH to be cached, if the cache controller is also enabled. Enabled Video BIOS access cached Disabled Video BIOS access not cached 8 Bit I/O recovery time The recovery time is the length of time which the system delays after the completion of an input/output request. It is measured by the CPU clocks. This delay takes place because the CPU is operating 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. 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. Memory hole at 15M-16M In order to improve performance, certain space in memory has been reserved for ISA cards. This memory must be mapped into the memory space less then 16 MB. Enabled Memory hole supported. Disabled Memory hole not supported. Peer concurrency Peer concurrency means that more than one PCI device can be active at a time. Enabled Multiple PCI devices can be active. Disabled Only one PCI device can be active at a time. Chipset special features When this is disabled, the chipset behaves as if it were the earlier version. The Choice: Enabled, Disabled. DRAM ECC/Parity select This item allows you to select between two methods of DRAM error checking, ECC and Parity. Memory Parity ECC check This item allows you to select among three methods of memory error checking, Auto, Enabled and Disabled. Single bit error report When a single bit error is detected, the offending DRAM row ID is latched. The latched Value is held until the software explicitly clears the error status flag. You can select Enabled or Disabled. L2 cache cacheable size This item determines the size of the L2 cacheability: 64MB / 512MB . Chipset NA# asserted This item allows you to Enable or Disable the Chipset�s NA# assertion, during the CPU writes cycles and CPU line fills cycles. Pipeline cache timing This item allows you to select two timings of pipeline cache, Faster and Fastest.

PCI slot IDE 2nd Channel This item allows you to designate an IDE controller board inserted into one of the physical PCI slots as your secondary IDE controller. Enabled External IDE controller designated as the secondary controller Disabled No IDE controller occupying any PCI slot. IDE PIO IDE hard drive controllers can support up to two separate hard drives. These drives have a master/slave relationship determined by the cabling configuration that is used to attach them to the controller. Your system supports one IDE controller, so the system support up to two separate hard disks. PIO means Programmed Input/Output. Rather than having the BIOS issues a series of commands to effect a transfer to or from the disk drive. PIO allows the BIOS to communicate with IDE controller, and then lets the controller and the CPU performs a complete task by themselves. This is simpler and more efficient (and faster). Your system supports five modes, numbered 0 (default) to 4, which stand for five different timings. When Auto is selected, the BIOS selects the best available mode. On-Chip Primary PCI IDE As stated above, your system includes two built-ins IDE controllers, both of which operate on the PCI bus. This setup item allows you to enable or disable the primary controller. You can choose to disable the controller if you want to add a higher performance or specialized controller.

DPMS Initial display power management signaling PM Timers The following four modes are Green PC power saving functions that are user configurable when User Defined Power Management selected. See above for available selections. Doze Mode When this mode is enabled, after a set time of system being inactive, the CPU clock will run at slower speed while all other devices still operate at full speed. Standby Mode When this mode is enabled, after a set time of system being inactive, the fixed disk drive and the video will shout off while all other devices still operate at full speed. Suspend Mode When this mode is enabled, after a set time of system being inactive, all devices except the CPU will shutoff. HDD Power Down When this mode is enabled, after a set time of system being inactive, the hard disk drive will be powered down while all other devices remain active. Power Down & Resume Events Power Down and Resume 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 the effect, the system remains alert for anything that occurs to a device that is configured as On, even when the system is in a power down mode. The following is a list of IRQ, Interrupt ReQuests, which can be exempted as much as the COM ports and LPT ports above can. When an I/O device wants to get the attention of the operating system, it signals this by causing an IRQ to occur. When the operating system is ready to respond to the request, it interrupts itself and performs the service. Same as the above, the choices are On and Off. Off is the default. When it is set Off, this function will neither prevent the system from going into a power management mode nor awake the system. • IRQ3 (COM 2 ) • IRQ4 (COM 1) • IRQ5 (LPT 2) • IRQ6 (Floppy Disk) • IRQ7 (LPT 1) • IRQ8 (RTC Alarm) • IRQ9 (IRQ2 Redir) • IRQ10 (Reserved) • IRQ11 (Reserved) • IRQ12 (PS/2 mouse) • IRQ13 (Coprocessor) • IRQ14 (Hard Disk) • IRQ15 (Reserved) PnP/PCI Configuration Setup This section describes how to configure the PCI bus. PCI, or Personal Computer Interconnect, is a system that allows I/O devises to operate at a speed close to the speed of the CPU itself when it communicates with its own special components. This section covers several technical items and we strongly recommend that only experienced users should make any change to the default settings.

Choices are Legacy ISA and PCI/ISA PnP. PCI IRQ activated by This option allows you to configure the active condition of PCI IRQ signals. Choices are Level and Edge. PCI IDE IRQ map to This option allows you to configure PCI IDE device. By default, PCI- AUTO, the BIOS will scan for PCI IDE devices and determine the location of the PCI IDE device. If you have equipped your system with a PCI IDE controller and specify the location of PCI SLOTx, the BIOS will assign IRQ14 for primary IDE INT#, IRQ 15 for secondary IDE INT#. If you set this option as ISA, the BIOS will not assign any IRQs even if PCI IDE card is found, because some IDE cards connect the IRQ14 and IRQ15 directly from the ISA slot through a cord. ( This cord is called Legacy Header). Password Setting When you select this function, the following message will appear at the center of your screen to assist you in creating a password. ENTER PASSWORD: Type the password, up to eight characters, and press . The password typed now will clear any previously entered password from CMOS memory. You should be asked to confirm the password.

IDE HDD Auto Detection The Enhance IDE features are included in all Award BIOS. The following is a brief description of this feature. 1. Setup Changes Auto-detection BIOS setup will display all possible modes that are supported by the HDD including NORMAL, LBA and LARGE mode. If the HDD does not support LBA modes, no ’LBA’ option will be show. If the number of cylinders is less than or equal to 1024, no ‘LARGE’ option will be shown. Users can select a mode which is appropriate for them. ROM/PCI/ISA BOPS CMOS SETUP UTILITY AWARD SOFTWARE, INC. ������������������������������������������������������������� ������������� ���������������� ��������������������������� �!��"��#���$���� ����������������������������������������������������������� ���� ���%�!�$������%&&%����&’%(��������)*����’������������������*’+&����� �)(���������������,� ���&�������������%&&%����*’+%�������&)����������)--(-��� *’+& Standard CMOS Setup CYLS HEADS PRECOMP LANDZONE SECTOR MODE Drive C : User (516MB) 1120 16 65535 1119 59 NORMAL Drive D : None (203MB) 684 16 65535 685 38 ---------- When the HDD type is in ‘user’ type, the ”MODE” option is open for users to select their own HDD mode. (2) HDD Modes The Award BIOS supports 3 HDD modes: NORMAL, LBA & LARGE NORMAL mode This is a generic access mode, neither the BIOS nor the IDE controller can make any transformation during access the HDD. The maximum numbers of cylinders, head and sectors for NORMAL mode are 1024, 16 & 63. no. Cylinder (1024) x no. Head ( 16) x no. Sector ( 63) x no. per sector ( 512) 528 Megabytes If user set his HDD to NORMAL mode, the maximum accessible HDD size will be 528 Megabytes even though its physical size may be greater than that. LBA (Logical Block Addressing) mode This is a new HDD accesses method to overcome the 528 Megabytes bottleneck. The number of cylinders, heads & sectors shown in the setup may not be the number physically contained in the HDD. During the HDD accessing, the IDE controller transforms the logical address described by sector, head & cylinder number into its own physical address inside the HDD. The maximum HDD size supported by the LBA mode is 8.4 Gigabytes that obtained by the following formula: no. Cylinder ( 1024) x no. Head ( 255) x no. Sector ( 63) x bytes per sector ( 512) 8.4 Gigabytes LARGE mode This is an Extended HDD access mode supported by Award Software. Some IDE HDDs contain more than 1024 cylinders without LBA support(in some cases, users do not want LBA). The Award BIOS provides an alternative to support these kinds of HDD. Example of the LARGE mode: CYLS. HEADS SECTOR MODE 1120 16 59 NORMAL 560 32 59 LARGE BIOS tricks the DOS (or other OS) that the number of cylinders is less than1024 by dividing it by 2. At the same time, the number of heads is multiplied by 2. A reverse transformation process is made inside INT13h in order to access the right HDD address. Maximum HDD size: no. Cylinder ( 1024) x no. Head ( 32) x no. Sector ( 63) x bytes per sector ( 512) 1 Gigabytes (3) Remarks In order to support the LBA or the LARGE mode of HDDs, some software must be involved in the BIOS. All of the software are located in the Award HDD Service Routine(INT 13h).If your system is under an Operating System that replaces the whole INT 13h, you may not be able to access a HDD with LBA (LARGE) mode.
