********************** 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 two options for installing this BIOS release:

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

2) From the bootable BIOS installation CD-ROM


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, ps10190.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.

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, slb8v190.iso,
provided in this distribution.

If you have CD burning software on your computer, chances are good it has set
itself up as the default handler for ISO CD-ROM images.  If this is the case,
the option to create the bootable CD-ROM from the BIOS Launcher, will launch
your CD burning software, ready to burn the ISO image to CD.  If your software
hasn't set itself up as the default handler for ISO images, we'll recognize
that fact, and let you know.

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 1, 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 DMI values, you can erase and re-use the
rewritable disc.

Note 2, The BIOS Launcher dialog offers the option to install the BIOS from a
bootable diskette.  Unfortunately, the BIOS image, and its flash utility are
too big to fit on a diskette.  If you make the bootable diskette, and boot
your PC from it, it will look for the BIOS on your CD/DVD drive.

IMPORTANT: 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.

Here are brief instructions for creating a CD from the ISO image using widely
available software.

* Roxio Easy CD Creator:
  Easy CD Creator 5, bundled with some Toshiba PCs, allows you to initiate
  the ISO image to CD burning process by simply double-clicking the .ISO file
  in Windows Explorer. Simply browse to the folder into which you downloaded
  the ISO image file and double-click to launch Easy CD Creator. Then put a
  blank CD-R media in your drive and click on the 'Record' button to begin
  creating the CD.

  Information about Easy CD Creator is available at

* Nero:
  Nero 6 is available for download as a fully-functional demo. Nero can be
  used to create a CD from your ISO image using either of the two following

	o In Nero Burning ROM go to menu option 'Recorder --> Burn Image' and
	  navigate to the drive/folder containing the ISO image you wish to
	  burn to CD.

	o In Nero Express select the option for 'Disc Image or Saved Project'
	  to select the ISO image file and burn to CD.

More information about Nero 6 and a downloadable demo is available at

Drag 'n Drop CD:
The Drag 'n Drop CD application bundled with some Toshiba PC models does not
support creating a CD from an ISO image.  You'll need to use a different CD
burning application. If Roxio Easy CD Creator (see above) is not on your PC,
one application that can be used with Windows XP is Alex Feinman's free "ISO
Recorder Power Toy". This software allows you to right-click on .iso files and
use Windows XP's built-in CD writing wizard to create CDs from ISO image files.

Information about the ISO Recorder Power Toy is available at

Note: Information about non-bundled software is provided "for your
      information".  Toshiba neither recommends nor supports software that
      is not bundled with our computers or purchased from
