********************** 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.  Toshiba HIGHLY recommends that the computer
is powered via the AC adapter during the entire BIOS update process.

In the event of a power loss during the BIOS update process, the BIOS Key
Installation Method, described below, can sometimes be used to recover from
the failure.  If it does not, you'll need to have your computer serviced by a
Toshiba Authorized Service Provider (ASP).  You can select an ASP in your
area at

Toshiba also recommends that you disconnect all peripheral devices from your
computer before you perform the BIOS update.  Peripheral devices include, but
are not limited to, docking devices (Desk Stations, port replicators), PCMCIA
and CardBus cards, USB and IEEE 1394 devices, printers, scanners, digital
cameras, etc.

On some models, it is not unusual to see a CMOS checksum 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 checksum error



There are five options for installing this BIOS release:

1) From the bootable BIOS installation diskette.  This is the recommeded
   procedure whenever a diskette drive (internal, USB, or PCMCIA) is
   available on the target system.

2) From within Windows NT-based operating systems (XP, 2000, NT 4.0) using
   the Windows-based BIOS installer.

3) At startup by holding down the key immediately to the left of the spacebar.

4) From the bootable BIOS installation CD-ROM

5) Run CHGBIOSA.EXE at the command prompt.


The BIOS installation launcher offers the option to create a bootable BIOS
installation diskette.  Simply select 'Diskette Installation' from the
Launcher menu and click 'Ok'.  You'll need to have a diskette drive
(internal, USB, or PCMCIA) installed, and a formatted 1.44MB diskette

Once the BIOS installation diskette has been created, install the BIOS 
using the following steps:

      o Connect the computer to AC power using the AC adapter.
      o Close all open programs
      o Insert the BIOS installation diskette into your diskette drive (A:)
      o Shut down the operating system.  With Windows, you may choose to 
        Restart rather than shutting down.
      o If necessary, restart the computer by pressing Ctrl-Alt-Del or
        turning the computer OFF then on again

The computer will boot MS-DOS from the BIOS installation diskette, and
initiate the Flash BIOS installation routine.  Please note that on systems
where only a USB-connected diskette drive is supported, you can force the
computer to boot from the USB-connected diskette by holding down the "U" key,
when powering-on the system.

When the Flash BIOS update is complete, a message like the one below will be

        Please push the RESET SW (or turn AC power OFF/ON) to restart!

                             ROM Write Successful!
                               Utility Finished!

Eject the diskette from drive A: and turn the computer OFF then ON, or press
the reset switch to restart your computer.


If you are unable to use the Windows self-extractor, the self-extracting
ZIP archive can be extracted using PKUnZip, Info-Zip, or an equivalent UnZIP
utility.  The Zip archive was created with Info-Zip (
and the self-extractor (SFX) is WinZip (

The WinImage self-extracting diskette image, 1400D13.EXE , is a 32-bit
Windows application that requires Windows 9x, Me, NT, 2000, or XP.
Information about WinImage is available at

For Linux or other operating systems, you can use the boot CD-ROM method or
you can create the BIOS installation diskette on a Windows-based computer,
and boot the Toshiba notebook using the BIOS installation diskette.


This release offers the option to install the BIOS directly from within
Windows NT-based operating systems.  To do so, simply select the 'Windows
Installation' option from the Launcher menu, and click 'Ok'.

Please close all programs before executing the Windows NT-based installer.

Due to the somewhat increased risk of errors updating the BIOS from within
Windows (as compared to using the boot diskette method), it is HIGHLY
recommended that the computer be connected to AC power via the AC adapter,
and that the power-save mode is set to 'Full Power' or the equivalent while
installing the BIOS.

The Windows NT-based BIOS installer, p0016v130.exe, will install the flash
BIOS when run under Windows NT 4.0, Windows 2000, or Windows XP.

The Windows NT-based installer requires Administrator priveleges on the
target system, and, for Windows 2000/XP, requires that the Toshiba Value-
added Logic Device driver (TVALD, or ACPI common modules) be installed and

Windows 95, 98, and Me are not supported.  If executed under Windows 9x/Me,
the Launcher will not offer the option to install from within Windows.


Your Toshiba computer has a special keyboard function to install an
updated BIOS image.  In this section, the term "BIOS key" refers to the
key immediately to the left of the spacebar.

To use this function, you can use the BIOS installation diskette created
using method 1, above, or simply copy CHGBIOSA.EXE and BIO0016T.COM to a
diskette.  Then insert the diskette and hold down the BIOS key while the
computer is powered on.  The computer MUST be in BOOT mode, not Resume
or hibernate mode.

This installation method will only work with the internal keyboard.  If
your computer is docked with the display closed and you are using an external
keyboard, the computer will need to be undocked and the internal keyboard's
key immediately to the left of the spacebar used.

When the computer starts up with the BIOS 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.'

On some models (Satellite 5005 and others) where a system status LCD is
included, this and all messages displayed during the BIOS key installation
processs will appear in the system status LCD rather than on the main
display panel.

Insert the diskette that contains CHGBIOSA.EXE and BIO0016T.COM,
and press any key.  The CHGBIOSA program will automatically load the
BIO0016T.COM file.

If your Toshiba PC is equipped with a bootable CD-ROM device (CD-ROM,
DVD-ROM, DVD-RW, DVD-Multi, etc.), and you have access to a CD writer
(burner, either installed in your Toshiba PC or in another PC), you can
create a bootable BIOS installation CD-ROM using the ISO CD image,
4a2v13.iso, provided in this distribution.  Once you create the bootable
CD-ROM, simply boot your computer from the resulting CD.

To boot from CD, you can either hold down the "C" key while you turn your
computer on, or you can use HWSetup to change the boot priority so the CD
drive boots before the HDD.

Note, if your CD burner supports it, you can use a rewritable CD (CD-RW) disc
to create the bootable BIOS installation CD-ROM.  Be sure to erase the 
rewritable disc (if it has data on it) before you proceed.  Once you are
finished updating your system's BIOS, you can erase and re-use the rewritable

IMPORTANT NOTE: Creating the bootable BIOS Installation CD requires a 
specific set of steps that is unique to each CD authoring application.  You
cannot simply copy the ISO image to a blank CD and expect to be able to boot
from it.

For your CD authoring/burning software, follow the instructions for creating
a CD from an ISO image.  Brief instructions for some CD authoring/burning
software can be found in ISOCDROM.TXT, which is included in this package.


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, 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, BIO0016T.COM is located.  Enter
the complete path and file name. Example: C:\4A2V13\BIO0016T.COM.

If your path for BIO0016T.COM is anywhere other than the root directory
of the A: drive (A:\BIO0016T.COM), CHGBIOSA.EXE will copy the BIOS image
file from its current location to the root directory of A: drive.

Optionally, the CHGBIOSA program can also be run from a single command
which includes the path to the BIO0016T.COM file.

   Example: CHGBIOSA C:\4A2V13\BIO0016T.COM
