Configuring the M6Mi

Although the M6Mi system board is packaged in protec­tive materials, it is important to use care while unpack­ing and setting up.
Static Electricity
The M6Mi is shipped from the factory in an antistatic bag. To reduce the possibility of damage, it is important to neutralize any accumulated static charges on your body before handling the board.
The best way to do this is to ground yourself using a special wrist or ankle strap. If you do not have a strap, you should touch both of your hands to a safely grounded object. After you have grounded yourself, ground the M6Mi via the solder pads surrounding one of its mount­ing holes. Once the M6Mi is removed from its packag­ing, place it on top of the antistatic bag. Carefully inspect the board for damage which may have occurred during shipment.
Office Environment
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.

Installing the M6Mi

Introduction
This section explains how to install the M6Mi 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 Section 1. Micronics recommends 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 Micronics’ Technical Support Department.
System Memory Support
The flexibility of the M6Mi is augmented by its support for Error Checking and Correction (ECC), Extended Data Out (EDO) DRAM memory and Fast Page Mode (FPM) DRAM memory. The M6Mi allows vast memory capability without worrying about memory errors. It does this by providing ECC which enables parity check­ing to detect and correct memory errors.
EDO memory is designed to keep data available to the processor for an extended period of time. The EDO memory support extends the performance of conven­tional DRAM memory. The result is an improvement in memory-access performance on the M6Mi system board.

Section 3: Installing the M6Mi

System Memory

System memory devices, commonly known as SIMMs, are necessary to operate the M6Mi system board. The M6Mi has six 32/36-bit SIMM sockets and can be up­graded to 384 Megabytes of RAM. In addition, support is provided for Error Checking (ECC), Extended Data Out (EDO) DRAM memory and Fast Page Mode (FPM) DRAM memory. This section will explain the type of SIMMs supported, list the rules for adding memory to the M6Mi, give some examples of common memory configu­rations and show how to physically install the new SIMMs.
For long term reliability, Micronics recom­mends using SIMMs with tin-plated contacts. The use of gold-plated contacts may conflict with the tin­alloy on the SIMM socket.
SIMMs Supported
The M6Mi supports the following types of 60 or 70ns SIMMs:
4MB (1MBx32/36) 8MB (2MBx32/36) 16MB (4MBx32/36) 32MB (8MBx32/36) 64MB (16MBx32/36)
Upgrading Rules
The following is a list of rules to follow when upgrading SIMMs. If you follow these rules, your upgrade should be trouble-free:
Use 70ns or faster SIMMs. Upgrade SIMMs one bank at a time. Each bank must
contain two SIMMs of the same size and preferably from the same manufacturer. For example, to add 16MB of memory to the system board, install two 8MB SIMMs into the same bank.
When installing SIMMs, fill Bank 0, then Bank 1, then Bank 2.

Page 22
Section 3: Installing the M6Mi
Mixing EDO and FPM Memory
The M6Mi can handle a combination of EDO and FPM memory. The memory will default to the speed of the slowest RAM installed.
Follow the rules below:
Install the two types of memory in separate banks. (For example, install EDO memory in Bank 0 and FPM memory in Bank 1.)
When installing SIMMs, fill Bank 0, then Bank 1, then Bank 2.
NOTE: Mixing EDO and FPM memory is not recom­mended.

Configuration
After the M6Mi system board and all hardware is in­stalled, the system is ready for configuration. Before turning on the computer, make sure all cables are cor­rectly connected and all jumpers are correctly set.
It is recommended you keep the computer cover off the first time you boot the system. This will make it easier to correct any difficulties that might arise.
Initial Boot Up
Power up the M6Mi. If the system does not properly boot, check all your cables and peripherals for bad connections. You may also get beep codes or error messages. If this occurs, consult Appendices B and/or 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.
M6Mi System Board Manual

Appendix C: Beep and POST Codes

Appendix
C
Beep and POST Codes
Beep codes are a series of beeps sent through the speaker which indicate a problem during the Power On Self Test (POST). If text appears on the video screen, the M6Mi has completed POST; any other tone from the speaker indicates something other than a POST error. These tones are not described in the tables on the following pages.
The beep error codes are a series of beeps. The duration of the beep tones are constant, but the length of the pauses between the beeps varies. For example: a 1-3­3 beep code will sound like one beep, a pause; three beeps consecutively, another pause and then three more beeps.
One beep code is often misunderstood. If a video card is not installed or is failing, the system board will generate a long-short-long-short beep code. This is often interpreted as a 1-2-1 beep code. But POST errors always vary in the length of the pause and not the duration of the beep tone.
Another way of identifying a POST error is to use a device called a POST card. This peripheral card is inserted into one of the ISA slots and has an LED (or LCD) read out showing the contents of port 80h.
The following tables list all beep codes and POST routines.

Appendix E: Updating the System BIOS

Appendix
E
If you encounter any problems during this process, or if you have questions about the procedure, please call Technical Support.
Updating the System BIOS
The Micronics 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. The filename will be either “FSH” (or FSH20, FSH20G, etc.) or “PHLASH.” Type this filename at the A:> prompt (but don’t include its extension), followed by a space and the BIOS ROM image’s filename. This file will be included in the download and has a file length of about 131K. For example, to update the M6Mi to BIOS version 01, you would type:
PHLASH M6Mi_01.ROM [ENTER]
4) Once the FLASH process has begun, select [Y]es, if prompted, to allow auto-sensing of the part (the FLASH chip itself).
5) 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 the BIOS is somehow erased or doesn’t seem to accept the upgrade, you can have your original BIOS chip reprogrammed manually by Technical Support. There is a $29.95 fee for this service, which includes shipping charges to send your FLASH EPROM chip

back to you. Also, a preprogrammed FLASH EPROM chip can be purchased from Technical Support for $50.00. Overnight shipping costs an additional $10.00. (Price and availability subject to change.)
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.
