This BIOS version is for the following computer series:

------------------------------------------------------------------------
  BIOS Version 5.50     For: 700CS, 700CT
------------------------------------------------------------------------

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 CHGBIOSA.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 (720KB) diskette.


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 CHGBIOSA.EXE program and the BIOS image file,
BOOTBIOS.COM, must be placed on a LOW DENSITY (720KB) diskette.  A high
density (1.44MB) 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 720KB diskette that contains CHGBIOSA.EXE and BOOTBIOS.COM,
and press any key.  The CHGBIOSA program will automatically load the
BOOTBIOS.COM file.


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

The CHGBIOSA.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 CHGBIOSA.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 CHGBIOSA.EXE
program is run.

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

NOTE!
-----

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


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

   Example: CHGBIOSA  C:\700BIOS\BOOTBIOS.COM
