Blistering Ultra DMA/33 Hard Disk Drive Performance With its integrated Enhanced PCI Bus Master IDE controller that supports the new Ultra DMA/33 protocol, this mainboard doubles Hard Disk Drive data transfer rates to 33MB/sec, compared to 16MB/sec for conventional PIO Mode 3, PIO Mode 4, and DMA Mode 2 devices. By reducing the CPU workload and increasing CPU utilization, Ultra DMA/33 significantly improves system performance when running applications under Windows 95® and Windows NT® environments. The Ultra DMA/33 protocol is completely backward compatible with conventional ATA-2 Hard Disk Drive devices; so the mainboard also supports existing PIO Mode 3, PIO Mode 4 and DMA Mode 2 devices using the same cable. With the integrated Enhanced PCI Bus Master IDE controller you can connect up to four Enhanced IDE peripheral devices to your system. All devices are categorized in the same way that IDE hard disks were configured in the past, with one device set as the master device and the other as the slave device. We recommend that Hard Disk Drives use the primary IDE connector and that CD-ROM Drives utilize the secondary IDE connector for optimum system performance.

s

Concurrent PCI Architecture The mainboard Concurrent PCI Architecture enables more efficient operation of CPU, PCI and ISA transactions for faster and smoother multimedia performance. It also allows the use of PCI 2.1 and 2.0 compatible add-on cards for long system life, built-in scalability and the flexibility to adapt your system for future applications.

2). Install System RAM Modules
DRAM Memory
The VX98 RAM is comprised of four industry standard 72-pin Single In-line Memory Modules (SIMMs) and one 168-pin Dual In-line Memory Module (DIMM). Each SIMM socket supports from 4 to 128MB, either 60ns or 70ns FPM (Fast Page Mode) (asymmetric or symmetric) and high-speed EDO (Enhanced Data Out) DRAM (parity is not supported). The DIMM socket is able to support up to 128MB EDO DRAM or lightning-fast SDRAM. Before making DRAM upgrades, you should verify the type and speed of the RAM currently installed from your dealer. Installing mixtures of RAM types other than those described in this manual, will have unpredictable results.

* This configuration has not been tested as of this writing. NOTE : DIMM1 only supports 3.3V (unbuffered) EDO and SDRAM modules. SIMMs and DIMM are not to be installed at the same time on this mainboard or else you will burn your memory. Mixing SIMMs and DIMM require 5.0Volt (signal level) tolerant memory chips which are currently unavailable. SIMMs (ECC memory or parity check is not supported) with latency time of 60ns, 70ns and DIMM with latency time of 10ns, 12ns is allowed on this mainboard.

NOTE : SIMMs in each bank must be of the same type; System BIOS automatically configures the memory size. When populating SIMMs in Bank 1, insert the SIMM module first in SIM2 slot before inserting in the SIM1 slot. Likewise when populating Bank 2, insert the SIMM module first in SIM4 slot before inserting in the SIM3 slot. In the event that Banks 1 and 2 will all be populated, insert the first SIMM module at SIM4, SIM3, SIM2, then SIM1.

Install DIMM
Dual In-Line Memory Modules (DIMM ) can be used when the SIMM sockets are not used. One socket is available for a 3.3Volt (power level) Unbuffered Synchronous DRAM (SDRAM) or Extended Data Out (EDO) DRAM of either 8, 16, 32, 64, or 128MB to form a memory size between 8MB to 128MB. One side (with memory chips) of the DIMM module takes up one row on the mainboard. Because the number of pins are different on either side of the breaks, the module will only fit in one orientation. DRAM SIMM modules have the same pin contact on both sides. SDRAM DIMM modules have different pin contact on each side and therefore, have a higher pin density. Complete the following procedures to install DIMMs: NOTE : Do not use memory modules with more than 24 chips per module. Modules with more than 24 chips exceed the design specifications of the memory subsystem and will be unstable. The notch on the DIMM module will shift between left, center, or right to identify the type and also to prevent the wrong type from being inserted into the DIMM slot on the mainboard. Ask your retailer for the specifications before purchasing.

1. Locate the DIMM slot on the mainboard. (See figure below.)

2. Install the DIMM straight down into the DIMM slot with both hands. 3. The clips of the slot will close up to hold the DIMM in place when the DIMM touches the slot bottom.

Remove DIMM
Press the clips with both hands to remove the DIMM.

Cache Memory
The mainboard comes with onboard 512KB synchronous 3V Pipeline Burst SRAMs. Cache memory access is very fast compared to main memory access. The cache holds data for imminent use. Since cache memory is from five to more than ten times faster than main memory, the CPU access time is reduced, giving you better system performance. Pentium mainboards may implement various types of L2 cache SRAMs. Pipeline Burst SRAM is one of them, delivering the best price performance ratio. They perform much better than asynchronous SRAMs. NOTE: The cache memory is not user upgradeable.

3). Install the CPU
The CPU module resides in a 321-pin Zero Insertion Force (ZIF) Socket 7 on the mainboard that is backwards compatible with ZIF Socket 5 processors. The CPU that came with the mainboard should have a fan attached to it to prevent overheating. If this is not the case then purchase a fan before turning on the system. Apply thermal jelly to the CPU top and then install the fan onto the CPU.

1

NOTE : Without a fan circulating air on the CPU and heat sinks, the CPU and/or heat sinks can overheat and cause damage to both the CPU and the mainboard. To install the CPU, first turn off the system power and remove its cover before doing the following: 1. 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. 2. Handle the chip by its edges and try not to touch any of the pins. 3. Place the CPU in the socket. The chip has a notched corner with the white dot to correctly orient the chip. Align the notch with pin one of the socket by pointing the white dot towards the end of the lever. Pin one is located in the blank triangular area where one hole is missing from that corner of the square array of pin holes. Do not force the chip as the CPU has a corner pin for three of the four corners, the CPU will only fit in one orientation. With the added weight of the CPU fan, the CPU should slide easily into the socket. 4. Once completely inserted, hold down on the fan and swing the lever to the down position to lock the CPU in place. 5. See the following sections for information on the CPU jumpers settings. NOTE : You must set jumpers for
PU to Bus Frequency Ratio" and PU External Clock (Bus) Frequency" depending on the CPU that you install.

4). Install Expansion Cards
The mainboard features three 16-bit ISA Bus expansion slots and four PCI Bus expansion slots. This section describes how to connect an add-on (expansion) card to the system's expansion slots. An add-on ISA/PCI expansion card is a printed circuit board that, when connected to the mainboard, allows you to increase the capabilities of the system. For example, an expansion card can provide video and sound capabilities. NOTE : Before installing an expansion card, make sure to unplug the power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both the mainboard and expansion cards. To install an expansion card, do the following: 1. 2. Remove the computer chassis cover and locate an empty ISA/PCI expansion slot. Read the expansion card documentation on any hardware and software settings that may be required to setup the specific card. Set any necessary jumpers on the expansion card. Holding the edge of the peripheral card, carefully align the edge connector with the expansion slot. (See figure on right.) Push the card firmly into the slot. Push in on one end of the expansion card, then the other. Use this ocking" motion until the add-on card is firmly seated inside the slot. Make sure that the card has been placed evenly and completely into the expansion slot. Replace the computer system cover. Setup the BIOS if necessary. Install the necessary software drivers for the expansion card.

Assigning IRQs for Expansion Cards
Some expansion cards need to use an IRQ to operate. Generally an IRQ must be exclusively assigned to one use. In a standard design there are 16 IRQs available but most of them are already in use by parts of the system which leaves 6 free for expansion cards. Currently, there are two types of ISA cards. The original ISA expansion card design, now referred to as egacy" ISA cards, requires that you configure the card jumpers manually and then install it in any available slot on the ISA Bus. You may use Microsoft Diagnostic (MSD.EXE) utility included in the Windows directory to see a map of the used and free IRQs. For Windows 95 users, the ontrol Panel" icon in y Computer" contains a ystem" icon which gives you a evice Manager" tab. Double clicking on a specific device gives you a esources" tab which shows the Interrupt number and address. Make sure that no two devices use the same IRQs or the computer will experience problems when two devices are in use at the same time. To simplify this process the mainboard 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. For older Legacy cards that does not work with the BIOS, contact your vendor for an ISA Configuration Utility.

5). Connector Cables and Power Supply
Connectors
NOTE : Some pins are used for connectors or power sources. These are clearly separated from jumpers. Placing jumper caps over these will cause damage to the mainboard. Ribbon cables should always be connected with the red stripe on the Pin 1 side of the connector. The four corners of the connectors are labeled on the mainboard. Pin 1 is the side closest to the power connector on hard drives and floppy drives. IDE ribbon cable must be less than 18in. (46cm), with the second drive connector no more than 6in. (15cm) from the first connector.

Setting BIOS Feature
The mainboard comes with the Award BIOS chip that contains the ROM Setup information of the system. This chip serves as an interface between the processor and the rest of the mainboard's components. This chapter explains the information contained in the Setup program and tells you how to modify the settings according to the system configuration. A Setup program built into the system BIOS, is stored in the CMOS RAM. This Setup utility program allows changes to the mainboard configuration settings. It is executed when user changes system configuration; user changes system backup battery; or the system detects a configuration error and asks the user to run the Setup program. At power-on RAM testing, the message Press key to enter Setup appears. If you are a little bit late pressing the mentioned key, POST (Power-On Self Test) will continue with its test routines, thus preventing you from calling up Setup. If you still need to call Setup, reset the system by simultaneously pressing the , and keys, or by pushing the Reset button on the system case. You can also restart by turning the system off and then back on again. But do so only if the first two methods fail. Use the arrow keys to select and press key to run the selected program.

Main CMOS Setup
When you run Setup, the CMOS SETUP UTILITY main program screen will appear with the following options:

A section at the bottom of the above screen displays the control keys for this screen. Take note of these keys and their respective uses. Another section just below the control keys section displays information on the currently highlighted item in the list.

Load Defaults
The oad BIOS Defaults" option loads the minimized settings for troubleshooting. oad Setup Defaults" on the other hand, is for loading optimized defaults for regular use. Choosing defaults at this level will modify all applicable settings.

Standard CMOS Setup
The tandard CMOS Setup" option allows you to record some basic system hardware configuration and set the system clock and error handling. If the mainboard is already installed in a working system, you will not need to select this option anymore. However, if the configuration stored in the CMOS memory on the mainboard gets lost or damaged, or if you change the system hardware configuration, you will need to re-specify the configuration values. The configuration values usually get lost or corrupted when the power of the onboard CMOS battery weakens.

The above screen provides you with a list of options. At the bottom are the control keys for this screen. Take note of these keys and their respective uses. Userconfigurable fields appear in a different color. If you need information on the selected field, press the key. The help menu will then appear to provide you with the information you need. The memory display at the lower right-hand side of the screen is read-only and automatically adjusts accordingly.

Date
To set the date, highlight the ate" field and then press the page up/page down or +/­ keys to set the current date. Follow the month, day and year format. Valid values for month, day and year are: Month: (1 to 12), Day: (1 to 31), Year: (up to 2099).

Time
To set the time, highlight the ime" field and then press the page up/page down or +/­ keys to set the current time. Follow the hour, minute and second format. Valid values for hour, minute and second are: Hour: (00 to 23), Minute: (00 to 59), Second: (00 to 59), just press the key twice if you do not want to modify the current settings.

Hard Disks
This field records the specifications for all non-SCSI hard drives installed in the system. The onboard PCI IDE connectors provide Primary and Secondary channels for connecting up to four IDE hard disks or other IDE devices. Each channel can support up to two hard disks; the first of which is the aster" and the second is the lave". For an IDE hard disk drive setup, you can:

·

Use the Auto setting for detection during bootup.

· ·

Use the IDE HDD AUTO DETECTION in the main menu to automatically enter the drive specifications. Enter the specifications yourself manually by using the ser" option.

The entries for specifying the hard disk type include CYLS (number of cylinders), HEAD (number of read/write heads), PRECOMP (write precompensation), LANDZ (landing zone), SECTOR (number of sectors) and MODE. The SIZE field automatically adjusts according to the configuration you specified. The documentation that comes with the hard disk should provide you with the information regarding the drive specifications. The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDI drives. This entry provides three options: Normal, Large, LBA, or Auto. Set MODE to the Normal for IDE hard disks smaller than 528MB; set it to LBA for drives over 528MB that support Logical Block Addressing (LBA) to allow large IDE hard disks; set it to Large for drives over 528MB that do not support LBA. Large type of drives can only be used with MS-DOS and is very uncommon. Most IDE drives over 528MB support the LBA mode.

Auto Detection of Hard Disks on Bootup
For each field: Primary Master, Primary Slave, Secondary Master, and Secondary Slave, you can select Auto under the TYPE and MODE fields. This will enable auto detection of your IDE drives during Bootup. This will allow you to change your hard drives (with the power off) and then power on without having to reconfigure your hard drive type. If you use older hard drives which do not support this feature, then you must configure the hard drive in the standard method as described above by the ser" option. NOTE : After the IDE hard disk information has been entered into BIOS, new IDE hard disks must be partitioned (such as with FDISK) and then formatted before data can be read from and write on. Primary IDE hard drives must have its partition set to active (also possible with FDISK).
