Configuring the Micronic
s C400
Although the Micronics C400 system board is packaged in materials that are designed to protect it from physical damage and static electricity, it is important to use care while unpacking the board and setting it up.
Static Electricity
The Micronics C400 is shipped from the factory in an anti-static bag. To reduce the possibility of damage from static discharge, it is important to neutralize any static charges your body may have accumulated before han­dling the board.
The best way to do this is to ground yourself using a special anti-static wrist or ankle strap. If you do not have an anti-static strap available, touch both of your hands to a safely grounded object, such as the power supply or chassis of a computer that is connected to the power socket. After you have grounded yourself, ground the Micronics C400 board via one of the solder pads that surround its mounting holes. When you remove the Micronics C400 from its packaging, place it on top of the anti-static bag, and carefully inspect the board for dam­age which might have occurred during shipment.
Environment Considerations
Make sure the finished computer system is in an area with good ventilation. The system should not be in direct sunlight, near heaters, or exposed to moisture, dust, or dirt.

Introduction
This chapter explains how to install the Micronics C400 system board, memory, CPU and peripherals.
WARNING: Before installing or removing any peripherals or components, make sure you have a clear work space and that you adhere to all anti-static precautions described in Chapter 1. Diamond recommends that only trained techni­cians install and configure the system board.
Damage which occurs to the board while adding or removing peripherals or components may void the warranty. If prob­lems arise while installing peripherals, contact the computer dealer where you purchased the peripheral or Diamond’s Tech­nical Support Department.
System Memory Support
The flexibility of the Micronics C400 is augmented by its support for EDO and SDRAM memory. The Micronics C400 supports ECC (with 72-bit DIMMs) via the chipset.
SDRAM speed and synchronous operation have enabled the breakthrough in memory-systems design needed to meet the demands of fast high-performance processors. SDRAM improves bandwidth to main memory because all address, data and control signals are synchronized with the system clock. With all operations synchronized, system wait states are reduced, thus providing increased performance over conventional DRAM.
The new PC-100 SDRAM memory has the same technol­ogy as standard SDRAM, but is faster due to its ability to support the new Intel BX chipset and system boards that support the 100MHz Front Side Bus speeds.
17
Installing the Micronic
s C400
Installation of the Micronics C400 system board depends on the type of case you use. The Micronics C400 is designed for the Mini ATX form factor and may be installed into most cases. Install the system board into the chassis using the tools and equipment required and make all necessary case con­nections.
NOTE: If you are unfamiliar with installing a system board, Diamond highly recommends that you read the computer user’s manual or contact your dealer’s technical support department.
Tools Required
Diamond recommends using the following tools to install the Micronics C400:
❏ Small Phillips screwdriver ❏ Tweezers or a pair of needle-nose pliers ❏ Tray (to hold loose screws)
Equipment Required
Diamond recommends using the following equipment with the Micronics C400 for a typical configuration:
❏ ATX chassis with standard hardware. ❏ A high-quality ATX power supply capable of providing
continuous power within a 3 volt range. A power filter may be used with a noisy AC power source.
❏ PS/2 mouse and compatible keyboard. ❏ Eight ohm speaker. ❏ Standard ribbon cables for internal connections. ❏ Standard power cord (grounded).

System Memory
System memory is necessary to operate the Micronics C400 system board. The Micronics C400 has three 3.3V unbuf­fered 64/72-bit, 168-pin DIMM sockets for a maximum of 768MB of SDRAM memory. Support is provided for stan­dard SDRAM (66MHz) and PC-100MHz SDRAM. This section list the rules for adding memory to the Micronics C400, give some examples of common memory configura­tions and show how to physically install the memory.
Adding Memory
The following is a list of rules to follow when installing DIMMs. If you follow these rules, your upgrade should be trouble-free:
❏ Use 8ns or faster PC-100 SDRAM DIMMs when using
a 100MHz bus speed processor.
❏ Use 10ns or faster SDRAM DIMMs when using a
66MHz bus speed processor. NOTE: PC-100 memory is backwards compatible to run at the 66MHz bus speed.
❏ Use only PC-100MHz DIMM modules for the 100MHz
Front Side Bus speeds (350-450). Due to the strict timing issues involved when operating at 100MHz, your system will not boot if non-compliant PC-100 DIMM modules are used.
For long term reliability, Diamond recom­mends using DIMMs with gold-plated contacts. The use of tin-plated contacts may conflict with the gold alloy on the DIMM socket.

Initial Boot Up
Power up the Micronics C400. If the system does not properly boot, check all your cables and peripherals for bad connections. You may also get POST codes or error messages. If this occurs, consult Appendix B and C for a guide to possible solutions.
After the system properly boots, it is ready to be config­ured. The following information explains the proper procedures for BIOS configuration.
Setup
The Setup program is used to configure the computer’s BIOS (Basic Input/Output System). The computer’s BIOS is responsible for configuring the system board and providing hardware information to the operating system. In order for the computer to run properly, run the Setup procedure after first installing the system board and whenever you make a hardware change to the system.

Special Features
The Micronics C400 achieves high reliability, performance and scalability with numerous features.
Intel’s 440BX AGPset
In the competitive world of system board chipsets, Intel’s new 440BX places at the top with its support for the
100MHz Front Side Bus (FSB) technol­ogy. The 440BX is the infrastructure behind the 100MHz FSB technology. Along with PC-100 memory and Intel’s new versions of the Pentium II processor family, the 440BX AGPset adds a new
data highway that should post a substan­tial increase in bus and memory access. The flexibility of the 440BX allows for support of the first generation Pentium II processors at 66MHz FSB speeds.
Accelerated Graphics Port (AGP)
With the introduction of the Pentium II and the 440LX AGPset, graphics took the next step onto the AGP free­way. The AGP bus is faster than the current 33MHz PCI bus. It pro­vides a direct connection between the graphics subsystem and system memory. AGP, with dual 528MB/s data path, sur­passes PCI’s 132MB bottleneck.
Chapter 5: Special Features
58
SDRAM (Synchronous DRAM)
SDRAM is memory that can synchronize itself with the computer’s clock. This synchronization reduces time delays and allows for fast consecutive read and write capability. SDRAM can add as much as 10% to the overall system performance.
Intel’s release of the 440BX AGPset allows SDRAM to operate up to a new standard at 100MHz. At these speeds, a new standard of SDRAM or PC-100 SDRAM is required. PC-100 MHz memory is backwards compatible to run at 66MHz, however, a non PC-100 SDRAM may not be used on a 100MHz FSB system.
Wake On LAN
This feature offers you a way to access a local-area or wide-
area network or modem to turn on desktop PCs remotely. The wake-up control located on the Micronics C400 system board collects input from a Wake On LAN enabled adapter and the PC's power switch. It then routes its output to the power-supply activation circuitry. You can power up your PC or multiple PCs from a remote location and manage networks more efficiently.
Wake On LAN, along with system management tools such as Intel LANDesk Client Manager, can work together to cut computing costs by allowing time-consuming PC man­agement tasks to be done when network bandwidth is less demanding.
Chapter 5: Special Features
59
Ultra DMA/33 IDE
A hard drive interface protocol that increases the burst data transfer rate to 33MBytes per second. Prior to this protocol, Mode-4 protocol has been the fastest at 16.6MB per second. This new protocol is supported by Intel’s 440LX and 440BX AGPsets.
Universal Serial Bus (USB)
The simple and flexible way to connect devices to your desktop or notebook PC. USB allows virtually unlimited PC
expansion with no more hassles over add-in cards, dip switches, jumper cables,
software driv­ers, IRQ settings, DMA channels and I/O addresses. With USB, you can attach and detach peripherals without open­ing the computer or even shutting it down.

POST Messages
During the Power-On Self Test (POST), the BIOS either sounds a beep code or displays a message when it detects a correctable error. The following tables list POST mes­sages for the ISA BIOS kernel.
Appendix
C
Message Solution
Beep Currently the only beep code indicates that a video error has
occurred and the BIOS cannot initialize the video screen to display any additional information. This beep code consists of a single long beep followed by two short beeps. Any other beeps are probably a RAM problem.
BIOS ROM checksum error ­System halted
The checksum of the BIOS code in the BIOS chip is incorrect; indicating the BIOS code may have become corrupt. Contact your system dealer to replace the BIOS.
CMOS battery failed CMOS battery is no longer functional. Contact your system
dealer for a replacement battery.
CMOS checksum error - Defaults loaded
Checksum of CMOS is incorrect, so the system loads th e default equipment configuration. A checksum error may indicate that CMOS has become corrupt. A weak battery may have caused this error. Check the battery and replace if
necessary. CPU at nnnn Displays the running speed of the CPU. Display switch is set incorrectly. The display switch on the moth er board can be set to either
monochrome or color. This message indicates the switch is set
to a different setting than indicated in Setup. Determine which
setting is correct, and then either turn off the system and
change the jumper, or enter Setup and change the VIDEO
selection. Press ESC to skip memory test The user may press Esc t o skip the full memory test. Floppy disk(s) fail Cannot find or initialize t he floppy drive controller or the drive.
Make sure the controller is installed correctly. If no floppy
drives are installed, be sure the Diskette Drive selection in
Setup is set to NONE or AUTO. HARD DISK initializing Please wait a moment... Some hard drives require extra time
to initialize. HARD DISK INSTALL FAILURE Cannot find or initialize the hard drive controller or the drive.
Make sure the controller is installed correctly. If no hard drives
are installed, be sure the Hard Drive selection in Setup is set
to NONE.
Appendix C: POST Messages
72
Message Solution
Hard disk(s) diagnosis fail The system may run specific disk diagnostic routines. This
message appears if one or more hard disks return an error when the diagnostics run.
Keyboard error or no keyboard present
Cannot initialize th e keyboard. Make sure the keyboard is attached correctly and no keys are pressed during POST. To purposely configure the system without a keyboard, set the error halt condition in Setup to HALT ON ALL, BUT KEYBOARD. The BIOS then ignores the missing keyboard during POST.
Keyboard is locked out - Unlock the key
This message usually indicates that one or more keys have been pressed during the keyboard tests. Be sure no objects are rest ing on the keyboard.
Memory Test : This message displays during a full memory test, counting
down the memory areas being tested.
Memory test fail If POST detects an error during memory testing, additional
information appears giving specifics about the type and location of the memory error.
Override enabled - Defaults loaded
If the system cannot boot using the current CMOS configuration, the BIOS can override the current configuration is a set of BIOS defaults designed for the most stable, minima l-performance system operations.
Press TAB to show POST screen System OEMs may replace the Award Software BIOS POST
display with their own proprietary display. Including this message in the OEM display permits the operator to switch
between the OE M display and the default POST display. Primary master hard disk fail POST detects an error in the primary master IDE hard drive. Primary slave hard disk fail POST detects an error in the secondary master IDE hard
drive. Resuming from disk, Press TAB
to show POST screen
Award Software offers a save-to-disk feature for notebook
computers. This message may appear when the operator re-
starts the system after a save-to-disk shutdown. See the Press
TAB ... message above for a description of this feature. Secondary master hard disk fail POST detects an error in the primary slave IDE hard drive. Secondary slave hard disk fail POST detects an error in the secondary slave IDE hard drive.

Updating the System BIOS
The Diamond system boards are designed so that the BIOS can be reprogrammed using a BIOS file. You can easily FLASH a BIOS by following the steps below:
1. After downloading the appropriate BIOS file from our BBS or Website, extract it to a bootable MS­DOS 6.X diskette.
2. Reboot your system with the MS-DOS 6.X diskette in the A: drive. To make sure a clean DOS environ­ment is loaded, press the F5 key while “Starting MS­DOS” is displayed. After the system has rebooted, the cursor will appear at the A:> prompt.
3. Now you can run the FLASH utility from the bootable floppy disk. Refer to the README.TXT file in­cluded with the BIOS update for detailed instruc­tions.
4. After the update process has completed and the system reboots, verify that the new BIOS version appears on-screen. If you have problems during this process, or if you have questions about the proce­dure, please call Technical Support.
NOTE: If you prefer to send your system board in for the upgrade, the RMA department offers this service free of charge if your system board is under warranty.
