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 http://pcrepair.toshiba.com

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 to save the CMOS data. You won't see the CMOS checksum error again.


There are two options for installing this BIOS release:

  1. From within Windows (7, Vista, XP) using the Windows-based BIOS installer.

  2. From the bootable BIOS installation CD-ROM
  1. Installation from within Windows XP/Vista/7    Install Now
    This release offers the option to install the BIOS directly from within Windows operating systems. To do so, simply select the 'Windows Installation' option from the Launcher menu, and click 'Ok'.

    Important Information Regarding This Installation Method
    Please close all programs before executing the Windows-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 REQUIRED 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-based BIOS installer, os2011331a_170.exe, will install the flash BIOS when run under Windows XP, Windows Vista, or Windows 7.

    The Windows-based installer requires Administrator priveleges on the target system, and requires that the Toshiba Hotkey Utility is installed and working.

    Windows operating systems older than XP are not supported. If executed under Windows 9x/Me, the Launcher will not offer the option to install from within Windows.


  2. Boot CD-ROM Installation Method   Create CD-ROM Now
    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, sc08v170.iso, provided in this distribution.

    If you have CD burning software on your computer (Windows Vista and 7 have it by default), chances are good it has set itself up as the default handler for ISO CD-ROM images. If this is the case, the link above, and 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 press the F12 key when prompted, 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 disc.

    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.
