Installation Instructions for Micro Firmware BIOS Upgrade Updates
=================================================================

NOTE: Use of these files is governed by the License Agreement
contained in the file LICENSE.TXT, included with this distribution.

This BIOS Update file will update prior revisions of Micro Firmware's
M4HS45G BIOS Upgrade to M4HS45G version 4.05.17.

In order to install this update, the M4HS45G BIOS must already be
resident on your PC. You can confirm this by booting your PC and
watching for the Micro Firmware BIOS part number which will appear on
the boot screen. DO NOT ATTEMPT TO INSTALL THIS UPDATE IF YOU DO NOT
SEE THE "M4HS45G" PART NUMBER ON THE BOOT SCREEN.

You may wish to obtain a copy of the latest system-specific
supplemental manual, which is available on our Web site in Adobe

BEFORE INSTALLATION
===================

Copy the files from this update distribution onto a blank diskette.

Run Setup, and make a note of your existing configuration.  Pay
particular attention to hard drive settings and the settings for
the onboard serial and parallel ports. Most settings are retained,
but checking your existing configuration is a good precaution in the
unlikely event that the flash installation is interrupted for any
reason.

Be sure that your data is backed up. This is a normal, everyday rule
of thumb that everyone should adhere to. Installing the new BIOS
revision in and of itself should not affect the data on your hard
drive(s) - however, it is especially important to have a back up of
any valuable data any time you make any changes to your PC
configuration.

In some cases our revision updates may be different enough from the
revision currently installed that the operating system may not be
happy with the change. Windows 95/98 may need to reboot a few times
to adjust to the changes or in some unusual cases it may be necessary
to reinstall everything on a blank drive.


INSTALLATION INSTRUCTIONS
=========================

1. Boot from clean DOS boot disk (such as WIN95/98 Startup Disk).

2. Insert the diskette containing the BIOS update files.

3. Type INSTALL NORECOVER to run the Flash BIOS installation program.
   The NORECOVER parameter allows the INSTALL program to skip the
   step of creating a recovery disk.

4. The first thing the installation program will do is examine your
   system to determine the current system settings. This allows the
   installation program to preserve many system setup options under
   the new BIOS. This will take a few moments.

5. Then the installation program will load the BIOS image from disk
   into RAM. A window will appear showing the progress. This should
   take just a few seconds. The Flash ROM will then be reprogrammed
   with the new BIOS. Once the programming is complete, the system
   will reboot with your new BIOS installed.

6. It is recommended to enter CMOS setup before allowing the system to
   boot to the hard drive so that you can verify that the hard drive
   settings are the same as before. It is also be recommended to
   verify that other CMOS settings are set the same as before. Refer
   to the system-specific supplemental manual for more details.
