When you insert the restore CD into your computer under Windows, you see a message indicating the CD isn't the right one for your computer.  Or, when you try to restore your computer back to the factory state using the restore CD, you see a "Wrong Machine" message.

"Restore CD" refers to the Restore CDs, Recovery CDs, Reconfiguration CDs, Configuration Builder CDs (CBCDs), or PIRAD CD/DVDs that came with your Toshiba PC.


Please verify that you are using the correct CDs for your computer. The CDs that shipped with a computer can only be used on that computer and not another model even with a similar model number. For example, you can not use Satellite 1800 CDs on a Satellite 1805, also you can not use Tecra 8100 CDs on another Tecra 8100 if the two Tecras have different part numbers.

If you're sure you're using the correct CDs, then you can download the Toshiba DMI Update Utility for Notebook PCs .  The DMI Update Utility will allow you to restore your model's identification information (DMI strings) so you can restore the factory software.

Please note:  The DMI Update utility must run from DOS boot media.  The package you download will guide you through the process of creating the DOS boot media.  To create the DMI utility boot disk, you'll need one of the following:

  • A bootable diskette (floppy) drive (FDD) and a blank diskette.
  • A bootable CD/DVD drive (CDR), access to a PC with CD writing capability, and a blank CD-r or CD-RW disk.

If you have a FDD, the FDD method is the simplest, most reliable method.  If no FDD is available, the bootable CDR is your only option.

Export Control and EULA
Use of any software made available for download from this system constitutes your acceptance of the Export Control Terms and the terms in the Toshiba end-user license agreement both of which you can view before downloading any such software.
