    Hey guys!

    I have a question for you. I have a modded bios for my laptop, with an .fd extension. A guy that modded it, posted a tutorial for emergency flashing, which includes removing a battery, AC adapter...

    Can I flash an bios with .fd extension, in DOS mode. I've managed to set it all up on my USB flash drive. I have an Insyde 2.13 BIOS. In DOS, I entered:

    First one is a BIOS package I downloaded from an manufacturer official site. Second one is the modded BIOS. This didn't work however, and it responded with a error:

    This modded BIOS has 4 mb. I also have an "de-capsulated" BIOS file with the same name, this one however has 8 mb. Which one should I use and how? Can this be done in DOS, or do i have to follow the recovery procedure? My current BIOS is working properly, but I need to change advanced options, in order to install an older OS.

    Thanks in advance guys!

    You can only bypass the security check by flashing via recovery. Official Windows or DOS based flasher checks the signature which is broken in case of modded bios.

    I see, it makes sense. Since my current bios is working, can recovery go wrong and brick my laptop, if modded BIOS name is wrong?

    If the name is wrong, recovery isn't triggered so nothing happens. Be sure to read the included instructions carefully.

    Alright, sounds good to me. One more thing: I've heard that a bios flash can brick the motherboard if trying to flash a laptop with a cracked OS installed. The one I have is legitimate, since I've bought this laptop 3 months ago. Is that true? Also, after flashing, can cracking the Windows OS ruin the BIOS?

    OS & bios are independent.
