Strange, new "BIOS Boot Logo" appears temporarily, with higher resolution, then disappears after 3'rd boot [Gigabyte Gaming X Z690]

[Yagma]

When I rebooted my PC today I was met with a new bios boot logo, that I have not seen before... actually this may have happened once a few months ago if I remember correctly. After that, the windows logo appeared and it was of a higher resolution, perhaps 1080p or 1440p... Suspecting the possibility that my videocard or motherboard may have been tampered with, I got the camera out and filmed it... it showed up a second time. On the third reboot, it went back to normal, as it was from the time I got this machine. Motherboard bios is up to date (a month old perhaps). There are two options for bootlogos, I disabled the bootlogo in general. When it is enabled, it displays a gigabyte logo, or something of that nature.

What could have caused this? Glitch, virus? I did not dump the graphics bios while it was booting like this... but I did after with GPU-Z. The file hash has not yet been recognized by virustotal, so it would appear it may be a unique, new, or modified bios. I have not flashed any modified bios with the new nvflash hack tool. When I submit the bios via GPU-Z, it says the bios was already uploaded previously, here: https://www.techpowerup.com/vgabios/236358/evga-rtx3080ti-12288-210804

But techpowerup hashes do not match what I dumped.

This logo is present on every AMI BIOS, it's just suppressed. Some setting may be causing the motherboard to run a full boot routine which displays the logo. It's definitely not a virus infection.

Regarding your VBIOS, is it the exact same revision as the one on the TPU DB? It might be a newer/older version. If it works, I wouldn't reflash it unnecessarily, though.

I did a full power cycle on reboot to help clear any potential persistent threats in the process, but even then I can only vaguely remember one time it did this before. Could have been a bios glitch. The fact it booted at a higher resolution also suggested to me it could have been vbios related.

Yes, its the exact revision, but with a different hash... I'm surprised virus total hasn't seen it before, it is 2 years old. It may be the original... I don't recall re-flashing it with anything newer.

A little something for the security enthusiasts out there:

Thats why I didnt touch this thread haha. OP sees an AMI logo thats always present but is likely just overwritten during screen refresh when another oprom is loaded. This is a timing thing imo, memory training, usb init, network etcetcetc.

Careful Patrick, you're scaring him!

Yep. Long boot option BIOS will show this screen because the splash image is disabled. Some have quick boot as a option by default and most have that splash screen so you never see the boots commands ,etc.

If AI can pass U.S. Medical Licensing Examination (USMLE) tests, then I'm sure it can be helpful with computer security; that said, Poe is often wrong, so as with everything, always try to confirm the information.

What would cause the initial boot screen and windows logo to run at a higher resolution than usual?

UEFI, once a year? Would be nice if it was all the time.

Yeah, my thoughts exactly

AI's good for entertainment or having it write some of your homework (maybe it'll write us a full referenced thesis one day and cause a cataclysm in modern academia - i'd love to see it), but I don't think we can safely bank anything regarding OpSec on it just yet.

Could just be a difference between quiet mode/performance mode BIOSes, TPU's database must not have that documented. It quite literally won't matter. There's no need to flash your card if it is working.

And for passing the U.S. Medical Licensing Examination (USMLE) to become an illegitimately certified pope fauci, to the same effect. I had asked a very knowledgeable computer security expert about malware persistence in memory while warm rebooting, he said at the time that while dram on the motherboard is volatile, with everything zeroed on boot, that this was not the case with the gpu bus or ram, (I can't remember which, i was hoping the AI would have scraped some data on that in its learning) in such a case, he suggested cold booting could remove such semi-persistent malware.

Courtesy of asking the same question on bing's gpt, I stumbled up on this

Buuuuttt

IBM conducted millions of dollars worth of research into the reasons why computer hardware without flaw operating within well defined parameters would have the occasional glitch. They found that cosmic rays with enough energy would occasionally strike the RAM or CPU and impart enough energy to flip a bit.

I would suggest cold booting your computer while moving it to a secure abandoned mine if the once a year glitch bothers you that much, it’s won’t eliminate glitches entirely, but it will lessen them.

Cool story bro.
