How Can i UPdate My Bios ?

Nothing good to say. But you asked so I thought it was worth the effort to assist. Depending on the laptop's age, a BIOS upgrade maybe a long shot.
I suggest the following links:

In Toshiba's words: Please note that you need to contact the Toshiba Computer Division for all questions related to Toshiba Laptop Computers, incuding hard drives, HD DVD drives and DVD-ROM drives that are installed in a Toshiba Laptop.

Mind you though, you should not do a BIOS flash unless it resolves the problem(s) you have now.
