MR_ZAPPA System BIOS and Flash Upload Utility
---------------------------------------------

Four files are included in this distribution kit.

MR_ZAPPA.BIO - MR BIOS (r) System BIOS
MR_ZAPPA.EXE - Flash Loader Utility
MR_ZAPPA.TXT - This file you're reading
AUTOEXEC.BAT - For Flash-Recovery disk

The System BIOS file contains the Microid Research BIOS ("MR BIOS (r)"),
customized for your Zappa motherboard.  It is designed to supercede the
Intel distribution (or AMI 1992 core) BIOS that is currently running
your computer.  The 1995 MR BIOS (r) core provides the latest state-
of-the-art BIOS technologies that automate most of 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 MR_ZAPPA.EXE Flash Loader.

The Flash Loader Utility is simple to use, and performs its job very
quickly.  Select option "3. Install" to initiate the Flash upload
procedure.  After it completes the Flash upload, it will direct 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 a 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.

Be advised that there is an element of danger in reprogramming the
computer's Flash System BIOS.  If the Flash Load procedure does not
complete for some reason (eg, if the power is shut off in the middle
of things), or if the image being uploaded into the Flash-ROM is not
appropriate, then the computer will simply not operate correctly (or
at all) anymore.  For this reason, your Zappa motherboard implements
a failsafe "Recovery" mode that can reload the original BIOS image
from floppy diskette, even when the existing System BIOS is faulty.
Please be sure to read the following section "Failsafe Recovery
Preparation" before uploading the MR BIOS (r) System BIOS.

------------------------------------------------------------------------------

-----------------------------
Failsafe Recovery Preparation
-----------------------------

The Zappa motherboard's Flash-ROM contains a protected "Boot-Block"
that cannot be erased.  Its purpose is to provide failsafe recovery
code that reloads the Flash-ROM in the event it somehow becomes
corrupted.  Under normal conditions, there should never be occasion
to activate the failsafe recovery mode (and you shouldn't play with
it).  However, you should be aware of this facility, and prepare the
necessary things in advance.  "Just in case".

The jumper "J1L1" located in the rear-left corner of the motherboard
is used to activate the Boot-Block Recovery mode.  When plugged 1-2
(the way it is now), Normal operation is selected.  When plugged 2-3,
the Recovery mode is selected.

When activated by plugging J1L1 to 2-3, the Boot-Block code performs
a minimal system boot, barely sufficient to load DOS from drive A:.
The recovery floppy in drive A: needs to be bootable (formatted "/S"
with DOS), and contain

   -  DOS and COMMAND.COM
   -  AUTOEXEC.BAT, specially prepared
   -  MR_ZAPPA.EXE, the Flash Loader Utility
   -  ZAPPA.BAK, the original BIOS backup image

Before uploading MRBIOS (r) into the Flash-ROM, be sure to prepare
a Failsafe Recovery diskette per these instructions:

Step 1
------
Format a floppy "/S" (with DOS and COMMAND.COM).

Step 2
------
Copy the contents of this distribution kit onto the floppy.  At minimum,
the files AUTOEXEC.BAT and MR_ZAPPA.EXE need to be transferred onto it.

Step 3
------
Generate ZAPPA.BAK backup image file:

Run the MR_ZAPPA Flash Loader program directly from floppy in drive A:.

Select option "1. Backup" upon entering the utility.  This will copy the
content of your computer's Flash-BIOS into the file ZAPPA.BAK.

Select option "5. Exit" to exit the program.  Type DIR A: and confirm
that ZAPPA.BAK was generated on the floppy in drive A:.  (If not, you
probably ran the program from drive C:, right?  In this case, COPY the
ZAPPA.BAK file onto the floppy).

Step 4
------
With this floppy in drive A:, reboot your computer via <Ctrl Alt Del>.
If the floppy is prepared correctly, its AUTOEXEC.BAT file should put
you directly into the MR_ZAPPA Flash Loader program.

Select option "2. Verify".  This compares the Flash-BIOS in your computer
with the backup file ZAPPA.BAK and reports the results.

Select option "5. Exit" to exit the program.

Step 5
------
Assuming Step 4 verification is successful, the floppy is now fully
prepared.  Set the Write-Protect notch, label it, and put it away
for safekeeping.

------------------------------------------------------------------------------

-------------------------------------
MR BIOS (r) Installation Instructions
-------------------------------------

Step 1
------
Prepare a Failsafe Recovery diskette according to instructions above.

Step 2
------
Invoke MR_ZAPPA.EXE Flash Loader, and select option "3. Install".

This loads the MR_ZAPPA.BIO file into Flash.  Wait briefly for a message
that indicates the procedure is completed.  Then press the reset button
or recycle your computer's power.

Be sure to wait for the completion message before resetting the computer.

Step 3
------
The first bootup after loading the new BIOS, you will be directed into
the BIOS Setup Utility.  Configure floppy drive(s) and other options.
Exit by pressing <F10>.

Step 4
------
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 5
------
Enjoy!

------------------------------------------------------------------------------

----------------------------------------
Failsafe Recovery - Corrupted Flash BIOS
----------------------------------------

In the unlikely event that your Zappa motherboard's Flash BIOS somehow
becomes corrupted and the computer will no longer boot, you will need
to reload its Flash from the Failsafe Recovery diskette.

First step: relax.  When the Flash BIOS is crashed, your computer will
be *real* unhappy with it.  It'll try to distress and panic you.  It'll
do anything (or nothing) within its power to get you to upload a new
BIOS image.  So, relax.  Then, when you've recovered, let's proceed to
recovering the Flash.

Begin by turning off all power, opening the computer case, and locating
the 3-pin jumper J1L1 in the rear left corner of the motherboard.  (It
also has the letters "RCVR" next to it).  Carefully using a small needle
nose pliers, unplug the J1L1 jumper from the upper 1-2 position, and
install it in the lower 2-3 position.

Turn the power back on, and insert the Failsafe Recovery diskette in
drive A:.  The floppy drive's activity LED will become illuminated
and stay that way for a minute or so, then it will turn back off.

When drive A: LED turns back off, the Failsafe Recovery procedure is
completed and the Flash BIOS is restored.  Shut off the computer's
power and replace jumper J1L1 to its original 1-2 position.

Notes:
------
(1) If you turn on your computer one morning and discover it won't
boot, the problem may have nothing to do with its Flash-BIOS.  The
computer might simply be unplugged or broken or etc.

(2) The Failsafe Recovery procedure reloads the Flash BIOS from the
file ZAPPA.BAK on the diskette.  If it was prepared per instructions
above, the original Intel/AMI BIOS will be restored.  (Recall that
step "1. Backup" copied the original Intel/AMI Flash image into the
ZAPPA.BAK backup file).  You can also make a Failsafe Recovery diskette
that reloads MR BIOS (r) instead, simply by COPYing or RENaming the
MR_ZAPPA.BIO file to ZAPPA.BAK on the diskette.  If you want to do
this, don't do it to the original (Intel/AMI) Failsafe Recovery disk.
Prepare a second floppy.  This way, you'll always be able to recover
things to the very original factory condition.  "Just in case".

(3) You might have noticed that the AUTOEXEC.BAT file on the Recovery
diskette contains the single line "MR_ZAPPA".  Therefore, when this
diskette is booted, the MR_ZAPPA.EXE Flash Loader is invoked.  Upon
being invoked, it checks the status of the J1L1 recovery jumper and
automatically executes the "4. Restore" option when J1L1 is plugged
in the 2-3 Recovery position.  (If J1L1 is in the Normal 1-2 position,
the menu is presented instead and MR_ZAPPA waits for your manual input).
