[HELP] New Asus MB boots into EzFlash tool

[PLAfiller]

Greetings all,

not my system, but a friend of mine. System specs:

MB: Asus TUF B760 Wifi DDR5
CPU: I5-13400
RAM: 1x32GB Transcend DDR 4800Mhz CL40
Drives: 2xPatriot P400 512GB + 1x2TB Kingston NV2
GPU: Palit RTX 3070 Gaming Pro OC

Problem description: parts arrived, we installed CPU, one Patriot drive and the one stick of RAM (no GPU, no more drives for the first boot). System booted immediately. Ram frequency was @4000Mhz, but in yellow

motherboard displayed "auto target DRAM frequency 4800 mhz", I just registered this, but continued to flash the board with latest BIOS from Asus: 1402.

After the flash board booted fine, but straight to Ez Flash utility. Ram frequency @4000mhz and doesn't respond to any changes from the BIOS menu. Installed Windows 11 fine, no errors, but on each boot the

motherboard goes to EZ Flash utility, not the general BIOS menu, but specifically to EZ Flash utility. Ram frequency is also not OK, still sitting at 4000mhz. Once you exit EzFlash utility and click on the boot drive PC

runs fine, plays any game you throw at it, no errors of any kind. In device manager everything is recognized except one Intel Serial IO Drivers, but I will sort it out.

Things I've tried:

- replaced the 2032 battery on the motherboard with brand new
- disabled Fast boot
- checked CSM and UEFI settings.

Things I am about to try: roll back one BIOS back to version 1202.

I will be posting a ticket to Asus support as well, but if any of you have any idea why it goes to EzFlash instead of booting directly I'd more than glad to receive some help.

Thank you in advance for your time.

If you have a bios at some root of storage device it will sniff it and usually reboots straight to EZ Flash

I am sorry, but I am not sure if I understand you right. I had the BIOS file on the same flash drive with the Windows 11, but once the flash is pulled out isn't it going to "forget" about it. Or you mean something else? Should I clear the CMOS with the jumper?

If you flashed it. And still left the USB drive in, it will still sniff it and boot to EZ FLASH.

You should always reset and load defaults after flashing any BIOS. ASUS itself recommends it.

I did load the defaults with F5, but not immediately after the flash. On one of the next reboots I went to defaults. So what now? Have just the .bin file on a flash drive and roll back? See if this solves the issue?

p.86 and 87.
paragraph 9.1
if i understand it correctly you have to select ezflash press enter and select YES or NO if you like to run it or not.
i think if you chose NO it will disable ezflash auto start during startup

Hi I had a similar problem and reinstalled the bios, turned out it hadn't finished properly so was waiting for that to happen. Once I had done it it booted just fine.

Same issue in attempting to upgrade to 1641.

After my first attempt, the machine worked fine, but would always boot into the EZflash part of BIOS setup. It showed that the BIOS was v1641.

Based on @Jbird's comment, I ran the BIOS upgrade again.

This time it stuck and the machine boots properly.

Gracias.
