help - downgrade bios

[baracoda]

hello there forum mates ,
not sure if i'm in the right section for a request but my bios is Insyde h20

my laptop is Toshiba L650-11F PSK1JE i bought it with bios 2.00 or 2.10 can't really remember exactly ( it was almost 2 years ) i did bios upgrade from toshiba website for drivers but it sucks !! totally !the DVDRW won't burn , the graphices card isn't rendering fast enough ( radeon mobility 5650 ) , rams 6GB and even Eco system for power saving which toshiba puts on site isn't supported on the new 1
current bios is 2.40 available ( http://support1.toshiba-tro.de/tedd-file...141325.zip )

i need to downgrade the bios to 2.00 or 2.10 please , i can't find any help and i searched the forums here a lot ( i believe )

i would really appreciate it
