********************** 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.

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.



There are two 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 the bootable BIOS installation CD-ROM


  1) Purchase the appropriate diskette drive for your model. Accessories are
     available directly from Toshiba at
  2) Enlist the help of a friend with a CD burner, and create the
     bootable BIOS installation CD on their system.
  3) Have a Toshiba Authorized Service Provider (ASP) install the BIOS 
     update for you.  The ASP may charge a fee for this service.  You can
     select an ASP in your area at


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, the system will reboot.  When the
screen goes black, eject the diskette from drive A: and Windows will start


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, 1386D16.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.

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,
1p20v16.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 change the boot priority in BIOS setup 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.
