    Hi, I'm new to mod BIOS. A few days ago, I updated a mod version for my Dell laptop and it's corrupted. Power is on but no POST. Before the update, I made an backup version through Intel Flash Descriptor which gave me a .bin file of 12MB.
    The problem is my laptop is shipped with 2 bios chips, W25Q64FV (8MB) and W25Q32FV (4MB), for security purpose (vPro I believe). This made me confused as I don't know how to recover the bios from the backup file.
    Please let me know what I should do rescue my laptop. Thanks in advance!
