This file contains information on the PFLASH BIOS utility
==========================================================================
-> Flash  EPROM  provides  you a convenient way to update your system BIOS  
   please note that updating your system BIOS is serious, only update when
   you need to do it.  Unnecessary updating can cause damage to the system
   which will not be covered under the warranty.
                                                                      
-> If  you update an incorrect file to your FLASH EPROM, the system may no
   longer  boot,  please  carefully follow the procedures in the manual or
   ask a qualified technician and/or call your dealer.
--------------------------------------------------------------------------
Flash EPROM updating procedures:
--------------------------------------------------------------------------
1. Enable  "Boot Block Programming"  jumper as shown in section III of the
   User's Manual.
2. Make  sure  the  system is running in real mode.  This utility will not
   operate  if  the  system is under protected mode or virtual mode.  This
   means  that you cannot reprogram the motherboard BIOS under the Windows
   environment or with any memory management software, including HIMEM.SYS.
   The following describes the easiest way run your system from real mode:
   1) Boot from a floppy disk formatted with the "FORMAT A:/S" command
      without creating CONFIG.SYS and AUTOEXEC.BAT files.
   2) If you are using MS-DOS 6.x, you can bypass the AUTOEXEC.BAT and
      CONFIG.SYS by pressing <F5> when  "Starting MS-DOS... "  line is
      displayed on the screen.
   3) For Windows 95 users, press <F8> to enter the Microsoft Windows 95
      Startup Menu and then choose "Safe mode command prompt only"

You  should  copy the contents of the \FLASH directory to your hard disk
drive. Once you have accomplished the above tasks, you can run the Flash
Memory  Writer  utility.  To  run  the  utility, change to the directory
containing PFLASH.EXE and then at the DOS prompt, type: [PFLASH] <Enter>

IMPORTANT: Flash type may be "SST" or "INTEL."  If "unknown" is displayed
after  "Flash type --,"  then  this  ROM  chip is not programmable or not
supported  with  the  PnP  BIOS and therefore cannot be programmed by the
Flash Memory Writer.

This screen provides three command options, which you can invoke by typing
the  corresponding  number  of  the command and pressing <Enter> key.  The
following describes each command:
--------------------------------------------------------------------------
IMPORTANT PROCEDURE:
--------------------
1.  Save Current BIOS to File (Perform upon first use of your system)
This  option allows you to copy the contents of the Flash memory chip into
a  file  in  the  \FLASH  directory.   This gives you a backup copy of the
original motherboard BIOS in case you need to re-install it. In such cases
where  the  data  on the chip get lost or corrupted, you can reprogram the
chip using this backup copy.
--------------------------------------------------------------------------
2.  Update BIOS Main Block from File
This option updates the BIOS from a file on the disk. This can either be a
new  file  or  a  backup  file  created by the "Save Current BIOS to File"
option. This will not update the Boot Block if the Boot Block is different.
You  will be prompted with the following if advanced features if necessary.

        Boot Block of New BIOS is different from old one !!!
        Please Use 'Advanced Feature' to flash whole bios !!!

3.  Advanced Features
Selecting this option brings up the Advanced Features screen for clearing
the  PnP  configuration  record  and  updating  the motherboard BIOS.  To
terminate  the program and return to the DOS prompt,  press the <Esc> key.
Selecting the third option displays the Advanced Features screen.

"Clear PNP ESCD Parameter Block"
This option erases the Plug-and-Play (PnP) configuration record.

"Update BIOS Including Boot Block and ESCD"
This option updates the Boot Block, the motherboard BIOS and the PnP ESCD
Parameter Block from a new BIOS file in the \FLASH directory.

To select an option,  type its corresponding number in the provided space
and then press the <Enter> key.  Follow these procedure to update the PnP
motherboard BIOS.

1.  Download the new BIOS by selecting the second command option from the
    Advanced  Features  screen.   The  program  displays  a second screen
    prompting  you  for  the name of the BIOS file.  Type in the complete
    name  of  the file, including the file name extension, and then press
    the <Enter> key.   The utility then downloads the new BIOS file.  The
    following message appears:

	DO NOT TURN OFF THE SYSTEM IF THERE IS A PROBLEM!

If you encounter problems while downloading the new BIOS, DO NOT turn off
your  system  since this might prevent your system from booting up.  Just
repeat  the  process,  and  if  the  problem still persists, download the
original BIOS file you created in step 1 above.

2.  After  successfully  downloading  the  new  BIOS file, exit the Flash
    Memory  Writer utility and then turn off your system.  Set the jumper
    back to its default setting of Programming "Disabled."

3.  Turn on the system and hold down <DEL> to enter BIOS Setup.  You must
    load "Setup Default" to affect the new BIOS. 

WARNING:  If the Flash Memory Writer utility was not able to successfully
download  a  complete  BIOS file, your system may not be able to boot up.
If this happens, your system will require service from your vendor.
