Toshiba 5005-s504 bios update

Question

ok so I have looked and looked online for help on how to update my bios on my toshiba 5005-s504 laptop I have seen multipule different solutions and eather I cant figuare it out or doing something wrong.... I'm experiancing a know issue with these laptops where it over heats every time I try to play a game or do any graphic design. I found the bios update on the web but every time I try to do the windows installation version it doesn't work and tells me I need something to do with the basic control, but what I'm wondering is, is there a way to get into the bios so I can upgrade it without using a blank cd or trying to find those annoying 1.44" floppys?please any help would be highly appreciated and you can reach me at [e-mail]
