Please consult everything useful here and your manual..to flash isn't just a game...it could hurt....
Use Toshiba's method of flashing bios but be careful if you Flash in Windows, expecially if it is a 64BIT machine...you have been warned.
In the Modified Folder there are 2 Modified Bios Files....use BIOS.WPH in the MOdified Folder with PHLASH16.
