question about bios from toshiba

[mystic324]

Hello,

I've a little question regarding the bios of my laptop (toshiba L850D-105 PSKECE). I've downloaded the last bios (http://support1.toshiba-tro.de/tedd-file...173533.zip) in the hope they have at least activated the amd-v feature but no. After extracting all the archives i see 2 folders the first win7 and second win8. i've flashed the bios who was in win7 no problem but no amd-v feature and after reading the web on how to activate it, i found a simple way by using efi boot with bootx64shell.efi the problem is i can't boot it. so i think the bios in win7 folder doesn't contain uefi boot. i check in windows 8 msinfo32, and it's tell me that bios mode is legacy. So i've decide to flash the bios that is in win8 folder and got 2 alerts the first about the fact that the bios are the same version, not really a problem, i've opened platform.ini then turned [Bios_Version_Check] Flag=1 to 0. but the second message even if i know how to disable it make me doubt to flash it insydeflash tell me "this bios is not for your Notebook PC." so it same to flash it even if i've the error message ? and in case of does someone know if it will give me the uefi boot option ?

thanks in advance for any help
