MR_ENDVR.BIO - MR BIOS (r) System BIOS MR_ENDVR.EXE - Flash Loader Utility MR_ENDVR.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 Endeavor 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 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_ENDVR.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 . 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 Endeavor 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 Endeavor 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 "J1N1" 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 J1N1 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_ENDVR.EXE, the Flash Loader Utility - ENDEAVOR.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_ENDVR.EXE need to be transferred onto it. Step 3 ------ Generate ENDEAVOR.BAK backup image file: Run the MR_ENDVR 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 ENDEAVOR.BAK. Select option "5. Exit" to exit the program. Type DIR A: and confirm that ENDEAVOR.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 ENDEAVOR.BAK file onto the floppy). Step 4 ------ With this floppy in drive A:, reboot your computer via . If the floppy is prepared correctly, its AUTOEXEC.BAT file should put you directly into the MR_ENDVR Flash Loader program. Select option "2. Verify". This compares the Flash-BIOS in your computer with the backup file ENDEAVOR.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_ENDVR.EXE Flash Loader, and select option "3. Install". This loads the MR_ENDVR.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 . 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 Endeavor 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 J1N1 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 J1N1 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 J1N1 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 ENDEAVOR.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 ENDEAVOR.BAK backup file). You can also make a Failsafe Recovery disk that reloads MR BIOS (r) instead, simply by COPYing or RENaming the MR_ENDVR.BIO file to ENDEAVOR.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_ENDVR". Therefore, when this diskette is booted, the MR_ENDVR.EXE Flash Loader is invoked. Upon being invoked, it checks the status of the J1N1 recovery jumper and automatically executes the "4. Restore" option when J1N1 is plugged in the 2-3 Recovery position. (If J1N1 is in the Normal 1-2 position, the menu is presented instead and MR_ENDVR waits for your manual input). ------------------------------------------------------------------------------ ---------------- Revision History ---------------- Microid Research Inc. is grateful for your suggestions, criticisms, and bug reports.
