2-6 Central Processing Unit (CPU)
The motherboard provides a 321-pins ZIF Socket 7. The CPU on mother board must have a fan attached to prevent overheating.
WARNING: Without a fan, the CPU will overheat and cause damage to both the CPU
and the motherboard.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and open it by first pulling the lever sideways away from the socket then upwards to a 90-degree right angle. Insert the CPU with the white dot as your guide. The white dot should point towards the end of the level. The CPU has a corner pin for three of the four corners, the CPU will only fit in the one orientation as shown as follow. With the added weight of the CPU fan, no force is required to insert the CPU. Once completely inserted, hold down on the fan and close the socket’s lever.
IMPORTANT: You must set jumper SW1 “DIP Switch for CPU Type Selection” and jumper
JP10 “CPU Voltage Selection” on page 5 depending on the CPU that you install.
2-7 Expansion Cards
First read your expansion card documentation on any hardware and software settings that may be required to setup your specific card.
Installation Procedure:
1. Read the documentation for your expansion card.
2. Set any necessary jumpers on your expansion card.
3. Remove your computer’s cover.
4. Remove the bracket on the slot you intend to use.
5. Carefully align the card’s connectors and press firmly.
6. Secure the card on the slot with the screw you remove in step 4.
7. Replace the computer’s cover.
8. Setup the BIOS if necessary.
9. Install the necessary software drivers for your expansion card.
8
Assigning IRQs for Expansion Cards
Some expansion cards may require an IRQ to operate. Generally an IRQ must be exclusively assigned to only one device. In an standard design there are 16 IRQs available but most of them are occupied by the system and leaves 6 free for expansion cards.
Either ISA or PCI expansion cards may require an IRQs. System IRQs are available to cards installed in the ISA expansion first, and any remaining IRQs can be used by PCI cards. Currently, there are two types of ISA cards. An original ISA expansion card design, know as “Legacy” ISA cards, they request configure the card’s jumpers manually and then install it in any available slot on the ISA bus, and other know as Plug and Play. You may use Microsoft’s Diagnostic (MSD.EXE) utility included in the DOS directory to see a map of your used and any free IRQs. For Windows 95 users, the “Control Panel” icon in “My Computer”, contains a “System” icon which gives you “Device Manager” tab. Double clicking on a specific device give you “Resources” tab which shows the Interrupt number and address. Make sure that no any two of devices use the same IRQs, or your computer will experience problems when those two devices are in use at the same time.
To simplify this process the motherboard has complied with the Plug and Play (PNP) specification which was developed to allow automatic system configuration whenever a PNP-compliant card is added to the system. For PNP cards, IRQs are assigned automatically from those available.
If the system has both Legacy and PNP ISA cards installed, IRQs are assigned to PNP cards from those not used by Legacy cards. The PCI and PNP configuration of the BIOS setup utility can be used to indicate which IRQs are being used by Legacy cards. For older Legacy cards that does not work with the BIOS, you can contact your vendor for an ISA Configuration Utility.
An IRQ number is automatically assigned to PCI expansion cards after those used by Legacy and PNP ISA cards. In the PCI bus design, the BIOS automatically assigns an IRQ to a PCI. To install a PCI card, you need to set something called the INT (interrupt) assignment. Since all the PCI slots on this motherboard use an INTA #, be sure that the jumpers on your PCI cards are set to INT A.
Assigning DMA Channels for ISA Cards
Some ISA cards, both Legacy and PNP may also need to use a DMA (Direct Memory Access) channel. DMA assignments for this motherboard are handled the same way as the IRQ assignment process described above. You can select a DMA channel in the PCI and PNP configuration section of the BIOS Setup utility. In the BIOS setup, you should choose “Yes” for those IRQ’s and DMA’s you wish to reserve for Legacy cards.

Figure 3-4
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. 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 conditions for your system. The only time you might consider making any changes would be if you discovered that data was being lost while using your system.
DRAM Settings:
The first chipset settings deal with CPU access to dynamic random access memory (DRAM). The default timings have been carefully chosen and should only be altered if data is being lost. Such a scenario might well occur if your system had mixed speed DRAM chips installed so that greater delays may be required to preserve the integrity of the data held in the slower memory chips.
Auto Configuration:
This item allows you select pre-determined optimal values for DRAM, cache, timing according to CPU type & system clock. The Choice: Enabled, Disabled. Note: When this item is enabled, the pre-defined items will become SHOW-ONLY.
L2 TAG RAM Size:
The system uses tag bits to determine the status of data in the L2 cache. Set this field to match the specifications (8 or 10 bits) of the installed tag RAM chip. The Choice: 8,10.
AT Bus Clock:
You can set the speed of the AT bus in terms of a fraction of the CPU clock speed (PCLK2), or at the fixed speed of 7.16 MHz. The Choice: 7.16 MHz, CLK2/2, CLK2/3, CLK2/4, CLK2/5, and CLK2/6
DRAM Timing:
The value in this field depends on performance parameters of the installed memory chips (DRAM). Do not change the value from the factory setting unless you install new memory that has a different performance rating than the original DRAMs.
21
The Choice: Normal, Fast, Slow.
SDRAM CAS Latency:
When synchronous DRAM is installed, the number of clock cycles of CAS latency depends on the DRAM timing. Do not reset this field from the default value specified by the system designer. The Choice: 2, 3.
Pipelined Function:
When Enabled, the controller signals the CPU for a new memory address before all data transfers for the current cycles are complete, resulting in faster performance.
The Choice: Enabled, Disabled.
DRAM Data Integrity Mode:
Select Parity or ECC (error-correcting code), according to the type of installed DRAM.
The Choice: Disabled, ECC, Parity.
Memory Hole At 15-16M:
You can reserve this area of system memory for ISA adapter ROM. When this 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.
The choice : Enabled, Disabled.
Host Read DRAM Command Mode:
This item allows you to select the type of Host Read DRAM Command Mode. The choice : Syn., Bypass.
Gated Clock:
Set the Gated clock is enable. When the Circuit is in idle state, the CLK sent to the circuit will STOP to reduce the power consumption. When any event come to the circuit, the CLK will recover and keep on running. This is to reduce the power consumption of the chip.
The choice : Enabled, Disabled.
G2H Buff Prefetch Threshold:
This setting will limit the Prefetch. If set to (1) No limitation : prefetch will keep on preftech if the prefetch has any empty line (2) Prefetch one line at most : The prefetch will only have one line prefetch in the buffer. If the buffer has one line in the buffer already, then no more prefetch will going until the buffer is empty. (3) Prefetch two line at most : The prefetch will only have two line prefetch in the buffer. If the buffer has two line in the buffer already, then no more prefetch will going until the buffer only have one line or empty.
The choice: Disabled, X-3 line, 1-2 line, 1-3 line, 2-2 line.
ISA Line Buffer:
The PCI to ISA Bridge has an 8-byte bi-directional line buffer for ISA or DMA bus master memory reads from or writes to the PCI bus. When Enabled, an ISA or DMA bus master can prefetch two doublewords to the line buffer for a read cycle.
The choice : Enabled, Disabled
22
Passive Release:
When Enabled, CPU to PCI bus accesses is allowed during passive release. Otherwise, the arbiter only accepts another PCI master access to local DRAM.
The choice : Enabled , Disabled.
Delay 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.
The choice: Enabled, Disabled.
Primary Frame Buffer:
Select a size for the PCI frame buffer. The size of the buffer should not impinge on local memory.

3-4-2 Description of the Green Functions

This motherboard supports HDD Power Down, Doze and standby power saving functions when Intel Pentium processor CPU is installed. The detail description of these functions are provided as following:
HDD Standby Mode
When system stop reading or writing HDD, the timer starts to count. The system will cut off the HDD power when timer ran out of time. The system will not resume operation until either a read from or a write to HDD command is executed again.
Doze Mode
The system hardware will drop down CPU clock from normal working speed when Doze mode timeout occurred.
Standby Mode
When the system standby mode timer ran out, it will enter the standby mode and retain CPU at slow working speed. The screen will be blanked out.
Suspend Mode
When the system suspend timer time out, the system will enter the suspend mode and the chipset will stop CPU clock immediately. The power consunption in Suspend Mode is lower than in standby mode. The screen is also blanked out.
27
PM Events:
AWARD BIOS defines 15 PM Events in the power management mode (Doze, standby & suspend). The user can initial any PM Events to be "Enable" or "Disable". When the system detects all of the enabled events do not have any activity, it will start the system Doze timer first if the "Power Management" isn't "Disabled". Once the system Doze timer timed out, it will process doze power saving procedure by starting the system standby timer. When the standby timer ran out and all of the "Enabled" events remains silent, the system will enter the standby mode. By now, the system will not only process the standby power saving procedures but also start the system suspend timer. When the suspend timer time out, all of the CPU clock will be stopped by dropping system clock down to zero and remains this way until any one of the "Enabled" event occurred.
Power Button Over Ride: User can choice power off mothod, by instant off or
4 sec off.
Ring Power Up Control: When setting this item Enabled, and press the power
button to power off. After Ring in the system will auto power on.
Power Up by Alarm: Default value is Disabled , when choice enabled you can
setting Date of Month, Time Alarm to setup the time and the date to power on
the computer.

3-5 PNP/PCI CONFIGURATION SETUP

This item allows you to determine install PnP OS or not. The choice: Yes, No.
Resource controlled by:
The Award Plug and Play BIOS has the capacity to automatically configure all of the boot and Plug and Play compatible devices. However, this capability means absolutely nothing unless you are using a Plug and Play operating system such as Windows95. The choice: Auto, Manual.
Reset Configuration Data:
Normally, you 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 such a serious conflict that the operating system can not boot. The choice: Enabled, Disabled .
IRQ3/4/5/9/10/11/12/13/15:
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 ISA Devices compliant with the original PC AT bus specification, requiring a specific interrupt ( such as IRQ4 for serial port 1). PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for PCI or ISA bus architecture. The choice: Legacy ISA, PCI/ISA PnP.
DMA0/1/3/5/6/7 assigned to:
When resources are controlled manually, assign each system DMA channel as one of the following types, depending on the type of device using the interrupt: Legacy ISA Devices compliant with the original PC AT bus specification, requiring a specific interrupt ( such as IRQ4 for serial port 1). PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for PCI or ISA bus architecture. The choice: Legacy ISA, PCI/ISA PnP.
PCI IDE 2nd Channel:
Select Disabled to deactivate the onboard PCI IDE second channel interface, if you install a secondary add-in IDE interface.
29
The choice: Enabled, Disabled.
PCI IRQ Activated by 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 otherwise by your system’s manufacturer.
The choice: Level, Edge.
PCI IDE IRQ Map to:
This allows you to configure your system to the type of IDE disk controller in use. By default, Setup assumes that your controller is an ISA (Industry Standard Architecture) device rather than a PCI controller. The more apparent difference is the type of slot being used.
If you have equipped your system with a PCI controller, changing this allows you to specify which slot has the controller and which PCI interrupt (A, B,C or D) is associated with the connected hard drives.
Remember that this setting refers to the hard disk drive itself, rather than individual partitions. Since each IDE controller supports two separate hard drives, you can select the INT# for each. Again, you will note that the primary has a lower interrupt than the secondary as described in “Slot x Using INT#” above.
Selecting “PCI Auto” allows the system to automatically determine how your IDE disk system is configured.

NOTE: HDD Modes The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE
NORMAL mode
Generic access mode in which neither the BIOS nor the IDE controller will make any transformations during accessing.
The maximum number of cylinders, head & 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 this 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
A new HDD accessing method to overcome the 528 Megabyte bottleneck. The number of cylinders, heads & sectors shown in setup may not be the number physically contained in the HDD.
During HDD accessing, the IDE controller will transform the logical address described by sector, head & cylinder into its own physical address inside the HDD.
The maximum HDD size supported by LBA mode is 8.4 Gigabytes which is obtained by the following formula:
no. Cylinder (1024) x no. Head ( 255)
35
Select Secondary Slave Option (N=Skip):N
OPTIONS SIZE CYLS HEAD PRECOMP LANDZ SECTOR MODE
1 (Y) 0 0 0 0 0 0 NORMAL
x no. Sector ( 63) x bytes per sector ( 512)
8.4 Gigabytes
LARGE mode
Extended HDD access mode supported by Award Software.
Some IDE HDDs contain more than 1024 cylinder without LBA support (in some cases, user do not want LBA). The Award BIOS provides another alternative to support these kinds of LARGE mode:
CYLS. HEAD SECTOR MODE 1120 16 59 NORMAL 560 32 59 LARGE
BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by dividing it by 2. At the same time, the number of heads is nultiplied by 2. Reverse transformation process will be made inside INT 12h in order to access the right HDD address 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
NOTE:
To support LBA or LARGE mode of HDDs, there must be some softwares involved. All these softwares are located in the Award HDD Service Routine (1NT 13h). It may be failed to access a HDD with LBA (LARGE) mode selected if you are running under a Operating System which replaces the whole INT 13h.
UNIX operating systems do not support either LBA or LARGE and must set to the Standard mode. UNIX can support drives larger than 528MB.
