Hi
Seems that something wrong has happened during the BIOS update.
Possibly the ROM module has not been flashed properly.
So the ROM module needs to be flashed once again.
The problem is that the Toshiba European driver page provides just the Win-based BIOS version and this can be updated only from Windows OS.
But I found the traditional BIOS on the Toshiba US page:

But I’m not quite sure if this BIOS would be compatible with your L40… so in such case you will need to ask the Toshiba ASP in your country for help and for flashing the BIOS using the BIOS crisis disk.
