- Contents, Overview and DISCLAIMER
- ---------------------------------
-
- BE ADVISED THAT THERE IS AN ELEMENT OF DANGER IN REPROGRAMMING YOUR
- COMPUTER'S FLASH SYSTEM BIOS. IF THINGS GO AWRY, YOU MAY NEED TO
- REPLACE THE MOTHERBOARD ALTOGETHER.
-
- This particular motherboard design is especially unforgiving of flash
- failure. (1) It's flash ROM does NOT implement a write-protected
- failsafe recovery "boot-block". (2) The flash ROM is soldered directly
- onto the system board. If anything at all happens to the flash that
- causes it to be inoperable, no practical method exists to restore it.
- No "recovery" utility can be run if the system won't boot. And the
- flash component cannot be removed and replaced. Thus, the motherboard
- will need to be serviced or replaced altogether if the flash content
- becomes polluted. There are many possible causes of flash corruption,
- including: (a) losing power during flash upload, (b) using a faulty
- or unsuitable flash loader utility, (c) uploading a faulty or unsuitable
- bios image, (d) a runaway or malicious program alters the flash content.
-
- DISCLAIMER
- ----------
- Microid Research Inc. is providing this documentation, flash loader and
- bios AS IS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS, IMPLIED OR
- STATUTORY, INCLUDING WITHOUT LIMITATION, ANY WARRANTY WITH RESPECT TO
- MERCHANTIBILITY OR ITS FITNESS FOR ANY PARTICULAR PURPOSE. MICROID
- RESEARCH INC. DOES NOT WARRANT THAT THE FUNCTIONS CONTAINED IN THE
- SOFTWARE WILL MEET ANY REQUIREMENTS OR THAT THE OPERATION OF THE
- SOFTWARE WILL BE UNINTERRUPTED OR ERROR-FREE. MICROID RESEARCH INC.
- SHALL NOT BE LIABLE FOR SPECIAL, INCIDENTIAL OR CONSEQUENTIAL DAMAGES
- OF ANY KIND. Your use of the software serves as explicit acceptance
- of these terms. So evaluate the risk carefully and, should you choose
- to use this software, take your time and please be careful!
-
-
- Three files are included in this distribution kit.
-
- MR_ATX.BIO - MR BIOS (r) System BIOS
- MR_ATX.TXT - This file you're reading
- MR_ATX.EXE - Flash Loader Utility
-
- The System BIOS file contains the Microid Research BIOS ("MR BIOS (r)"),
- customized for your Intel ATX (Advanced/ATX) motherboard. The 1995
- MR BIOS (r) core provides the latest state-of-the-art BIOS technologies
- that automate your computer's setup and deliver unmatched performance
- and utility.
-
- Unlike most programs that you are familiar with, the System BIOS does
- not execute from disk. Instead, it is stored in a Flash-ROM component
- that resides on the motherboard and begins executing immediately upon
- powerup. This Flash-ROM can be reprogrammed by means of a Flash Upload
- Utility. In order to install MR BIOS (r) in your computer, you'll need
- to reprogram its Flash-ROM through use of the Flash Loader utility.
-
- The Flash Loader provides a simple menu of 3 options (4, including
- "exit"). There are two objectives of this utility. First, it
- provides the facility to copy the existing BIOS into a disk-file
- for backup purposes. This is option "1. Backup". The companion
- function "2. Verify" allows you to confirm the backup file matches
- the existing BIOS. The other purpose of the Flash Utility is to
- install a new BIOS, accomplished through option "3. Upload".
-
- Be sure to backup the original BIOS before uploading MR BIOS into
- the Flash-ROM. Otherwise, you won't be able to uninstall MR BIOS
- should you want to do so. Even if you're sure you won't, it is a
- good practice to retain all original equipment that is supplied with
- your computer, "just in case".
-
- The exact steps for uploading MR BIOS are enumerated in the Instructions
- section below. Assuming you have followed those instructions and the
- upload has just completed, the Flash Loader will display a message
- directing you to reset the computer or re-cycle its power. Upon doing
- so, you will be greeted with an alarming message that the "CMOS Memory
- is Corrupt", and the BIOS Setup Utility will be activated. Don't be
- alarmed. The Flash Loader Utility intentionally clears the CMOS to
- simulate a factory-new condition and provoke the Setup session.
-
- Upon arriving in the Setup Utility, you will need to reset the time
- and date, and manually input the type(s) of Floppy drive(s) in your
- computer. Beyond that, everything else will already be set for optimal
- performance and you can simply exit by pressing <F10>. Or, you might
- browse around and tailor some options like Password Security or Power
- Management per your preference. After this Setup session, your computer
- will reboot thereafter without any hysterical messages.

- MR BIOS (r) Installation Instructions
- -------------------------------------
-
- Step 0
- ------
- Please read and understand the DISCLAIMER stated above.
-
- Step 1
- ------
- Disable power management in the BIOS Setup Utility.
-
- Step 2
- ------
- Boot your computer "clean", to a non-Protected-Mode DOS environment.
- This is easily done by booting a floppy that contains only DOS, but
- neither CONFIG.SYS nor AUTOEXEC.BAT.
-
- Step 3
- ------
- Invoke the MR_ATX Flash Loader by typing "MR_ATX" at the DOS prompt.
-
- Step 4
- ------
- Select option "1. Backup" to make a copy of the original BIOS that
- came with the motherboard. You will need to select a filename
- for the backup file - a good name would be "ORIGINAL.BIO".
-
- Step 5
- ------
- Select option "2. Verify" to confirm the backup was successful.
- The status will be reported to you, either success or failure.
-
- If it worked OK, proceed to Step 6. Else figure out what is wrong
- and correct it. Repeat Steps 4 and 5.
-
- Step 6
- ------
- Select option "3. Upload" to install MR BIOS into the Flash-ROM.
- You will need to enter the filename of the MR BIOS image that came
- with this distribution kit. (It should be MR_ATX.BIO, unless
- somehow this documentation has gotten out-of-sync. Tell us!)
-
- Step 6a
- ------
- The upload process may take up to 15 eternal seconds, during which
- time you are likely to begin worrying. Relax, and do NOT shut off
- the power or otherwise disturb the computer.
-
- You'll be notified with a message on the CRT when the upload has
- completed. Then, and not before then, restart the computer.
-
-
- Step 7
- ------
- The first bootup after loading the new BIOS, you will be directed into
- the BIOS Setup Utility. Configure time, date, floppy drive(s) and other
- options. Exit by pressing <F10>.
-
- Step 8
- ------
- Win95 Users: In a few installations, Windows 95 has been reported to
- "remember" certain properties of the BIOS that has been replaced by
- MR BIOS. This can lead to some bewildering behavior. The best rule
- of thumb is to unconditionally run Win95's "Hardware Wizard" once after
- installing MR BIOS. If weirdness persists, use the sledge-hammer
- approach and run Win95's "Setup".
-
- Step 9
- ------
- Enjoy!
-
- ------------------------------------------------------------------------------
-
- ----------------------------
- Un-Installation Instructions
- ----------------------------
-
- Follow Steps 6-8 above, exactly as with installing MR BIOS, but instead
- specify the Backup File. If you followed the instructions above, the
- Backup file was created in Step 4 before you installed MR BIOS.
-
