At the end I managed to update all BIOS of my machines by using the manifacturer original zip file.

Once extracted there are various files, fun part they changed the name of the main executable that had to be run via EFI with a less obviousy one and also added a FLASH.NSH file where .NSH are the EFI equivalents of .BAT in Windows and .SH in Linux.

So here's the procedure: unzip the ZIP content and put it in a flash drive, at the startup go in BIOS settings and select "Boot EFI shell", when the boot is complete go inside the flash drive content with cd fd0 or similar command where fd0 is your flash drive. At this point I first used the utility provided to do a backup copy of the current BIOS and then ran the FLASH.NSH file, then reboot and remove the external flash drive.

r/techsupport on Reddit: How can I update my Bios?
March 5, 2021 -

I've found out that my BIOS Version/date is: "American Megatrends Inc. 1.00, 10/19/2017", How can I update it?

I've found this page: "https://www.ami.com/products/firmware-tools-and-utilities/bios-uefi-utilities/" but I'm not sure if this is what I need, or what of the four links I should download.
I'm using Windows 10, if there is the need to know other things, just let me know.

Thank in advance!

Why does my PC restart, but the BIOS update never installs?
This usually means the update didn’t copy to the system firmware correctly. Try running the update tool again as an Administrator. If it still fails, check if your antivirus or BitLocker encryption is blocking the update. Temporarily disabling these often solves this type of problem.

American Megatrends BIOS Update | A Safe, Step-by-Step Guide
Can I update my motherboard's BIOS from inside Microsoft Windows (@BIOS, Live Update, etc.) or should I use the UEFI tools only?
You could update in Windows, but it is safer to use the UEFI tools: ASUS EZ Flash, MSI M-Flash, GIGABYTE Q-Flash, ASRock Instant Flash. Windows crashes and background processes add risk. Use a Windows-only EXE method only if the manufacturer explicitly requires it.

Why do I keep seeing "BIOS Update Failed – Secure Boot or BitLocker enabled" message?
Some OEM BIOS update files cannot flash when Secure Boot or BitLocker is active. Suspend BitLocker (Control Panel → BitLocker → Suspend Protection) and try again. Secure Boot does not usually trigger a BIOS update issue, but check your OEM’s instructions just in case.

November 8, 2024 - As you know, the procedure is to download the most recent BIOS from the manufacturer, then copy the CAP file and the Microsoft Windows 'renamer' executable to the root of the USB stick, use the renamer to rename the CAP file - and likely do something else to the CAP file - then go back into BIOS, where - in my case - the ASUS EZ Bios Update utility recognizes the now-renamed CAP file and updates the BIOS.

1 day ago - American Megatrends had a strict OEM business model for AMIBIOS: it sold source code to motherboard manufacturers or customized AMIBIOS for each OEM individually, whichever business model they require. AMI does not sell to end users, and itself produces no end-user documentation or technical support for its BIOS firmware, leaving that to licensees.

r/techsupport on Reddit: How to update my AMI BIOS?
November 12, 2025 -

Okay. I give up. Event viewer occasionally says Secure Boot CA/keys need to be updated. For other reasons it seemed like the BIOS needed to be updated but it was a hassle so I put it off. But I have no idea which exact utility and variant I need to use to update my BIOS. Sure, we are told to download the correct update file from your computer or motherboard manufacturer's website and etc but it isn't always clear to the ignorant such as myself which is the correct update file and/or utility.

BIOS Version/Date: American Megatrends International, LLC. F3 Y1, 1/19/2022

SMBIOS Version: 3.3

BIOS Mode: UEFI

BaseBoard Manufacturer: Gigabyte Technology Co., Ltd.

BaseBoard Product: B550 UD AC

BaseBoard Version: Default string
