This BIOS version is for the following computer series:

------------------------------------------------------------------------
  BIOS Version 6.00     For: Satellite 200, 205
------------------------------------------------------------------------

This BIOS version is Windows 95 compatible and supports Plug and Play
functionality.

******************** BIOS INSTALLATION INSTRUCTIONS ********************
************************************************************************

There are two ways to install this BIOS version:

1) At startup by holding down the F12 key.

2) Run CHGBIOS.EXE at the command prompt.
   

********************************** CAUTION! *******************************
***************************************************************************
During the upgrading of your computers BIOS, if the computer loses power or
fails to complete the process of upgrading the BIOS, the existing BIOS in
the computer may become damaged. In the event of this occurring, the
F12 Installation Method, described below, can be used to recover from
this error condition.  

If you are upgrading a number of computers with this BIOS, the F12 
installation method is the quickest but does require a separate low
density (720 Kb) diskette.

It is recommended that all PCMCIA cards be removed from the system prior to
upgrading the BIOS.  Also advisable is removing the computer from an attached 
Enhanced Port Replicator.

It is common to see a CMOS error when you first reboot the computer after 
installing the new BIOS.  If you see this message on your screen, press F1 as 
instructed.  This displays the "TSETUP" screen. Press <End> to save the CMOS 
data.  You won't see the CMOS error again.



1) F12 INSTALLATION METHOD
---------------------------

Your Toshiba computer has a special keyboard function to install an
updated BIOS image.

IMPORTANT!
----------
To use this function, both the CHGBIOS.EXE program and the BIOS image file,
BIOFCD5.COM, must be placed on a LOW DENSITY (720 KB) diskette.  A high
density (1.44 MB) floppy disk will not work.

To use this function, hold down the F12 while the computer is powered on.
The computer MUST be in BOOT mode, not Resume mode.

The F12 installation method will only work with the internal keyboard.  If
your computer is docked with the display closed and are using an external
keyboard, the computer will need to be undocked and the internal keyboard's
F12 key used.

When the computer starts up with F12 key depressed, the following 
message appears:

'Ready for BIOS update. Place the BIOS diskette in the drive, and press 
any key when ready to proceed.'

Insert the 720 KB diskette that contains CHGBIOS.EXE and BIOFCD5T.COM, 
and press any key.  The CHGBIOS program will automatically load the
BIOFCD5T.COM file.


2) RUN CHGBIOS.EXE AT THE COMMAND PROMPT
----------------------------------------

The CHGBIOS.EXE program is designed to be run from the MS-DOS command
prompt.  It cannot be run in a DOS box inside of Windows 3.1x, Windows 95,
OS/2 or other operating systems.  It also will not run if a Memory Manager,
like EMM386, is loaded.  The CHGBIOS.EXE program can be run from a
floppy disk, hard drive, or PCMCIA drive.  However, you will need a floppy
diskette (high or low density) in your A: drive at the time the CHGBIOS.EXE 
program is run.

When the CHGBIOS.EXE program is executed by itself, it will prompt you
to specify where the BIOS image file, BIOFCD5T.COM is located.  Enter 
the complete path and file name. Example: C:\BIOS\BIOFCD5T.COM.

NOTE!
-----

If your path for BIOFCD5T.COM is anywhere other than the root directory 
of the A: drive (A:\BIOFCD5T.COM), CHGBIOS.EXE will copy the BIOS image
file from its current location to the root directory of A: drive.


Optionally, the CHGBIOS.EXE program can also be run from a single command
which includes the path to the BIOFCD5T.COM file.

   Example: CHGBIOS  C:\BIOS\BIOFCD5T.COM
