Hey folks! I just want to welcome all the fellow techy folks to the channel. I focus on PC hardware, but that doesn't prevent me from occasionally working with other tech as well. Hope you enjoy the content, and thanks for dropping by!

Hotflash takes me back. I flashed the wrong BIOS on an old mobo and did this trick to recover it. I fired up another motherboard and took the BIOS chip out while it was on. Put the bad BIOS chip in and then flashed it with the correct BIOS. Swapped them back around so I had two working motherboards.

Motherboard manufacturers hate this one trick!

i was looking for a way to update the bios, this is a lot simpler. but you could buy some blank chips and a programmer. the programmer costs almost as much as a pre programmed chip though

[remixislandmusic]

Annoying that they didn't give the board as many bios updates as they should, but at least they are basically using an off the shelf board so you don't have to deal with proprietary nonsense

Or, Something else that you can dive into if you want more content, I have been meaning to do a video on it, but I just don't have the time.

You could simply by yourself a Cheap CMOS Flasher, Connect it to the BIOS chip you already have, Wipe the CMOS, then Flash the CMOS of the BIOS you want to flash, it won't stop you even if its the wrong BIOS Version, but assuming you made sure to grab the correct version for the retail board, you flash it, and then you are up and running without having to rely on someone else sending you the correct BIOS Chip. This is how these sellers make those chips to begin with, so you just cut out the middle man and do it yourself. The other benefit of learning how to do this yourself is you can bring Boards back from the dead that have been bricked by a bad flash, I have used at least 5 to 6 dozen times in the past decade to bring back all kinds of boards, even new ones that don't have socketable CMOS chips, because your CMOS Flasher can simply connect to the BIOS Chip directly on the motherboard (its an alligator type clip you connect to the exposed pins on the CMOS Chip on the board itself.)

So if that works would there be a way to switch a amd cpu slot fir a intel slot

[Documenting_Life_]

So this could be related to laptops as well right ? Thanx

I'm curios if a bios chip could have been damaged during shipping. I bought a refurbished Asus B85M-G I can't get to post the seller tested the board before shipping I know this because he forgot to remove his test CPU I can get it to tell me it has no ram through a speaker I hooked up to it. Near as I can tell the bios chip is exactly the same as the chip on my Asus H18M-E. I was thinking of taking a stab at swapping out the bios chip and see if it has any effect but I'm not certain it's even worth trying it's a fair amount of work to swap my motherboards out and I don't have like a test power bench which I should make but I only repair my own system these days so it's kinda a waste of time and money. Thoughts ideas tips will be welcomed.

dang what if i swapped the BIOS of a Dell Precision 5820 by taking another one and soldering it on

[frankenstein]

Are you concerned about seller on eBay putting malisha code on the chip(bios) ? Myself I don't know how to barebone flash the chips. Ty for the great idea thow.. I have a 12+ yer old pentium4 mobo that I need to figer out if it can be safe to use in my network O_o

[minecraftphenom]

This is pretty cool that you figured this out. It's pretty not cool that ASUS did that lol

[jonronnquist]

I suspect the company that made the prebuild system is the problem here rather than ASUS. They could probably keep up with the BIOS updates if they wanted to, but opt not to in order to keep customers upgrading their PCs. That's what the cynic in me thinks anyway.

[Felix_Fausto]

I've done this with some Foxcon mbs

[andyf]

I bricked my bios chip and it would not flash again right so I got an old ASU’s mb out and took the chip out put it in mine and booted it up right into windows had a totally wrong bios chip in lol

[DiotraxSecondlives]

i got so scared when it cut to black and the uefi logo appeared. don't do that lol

[alexandreduchesne]

Best bios for Asus ROG Strix GA15 G15DH B450 AM4

[Smedleydog]

I don't ever buy pre-built systems so this isn't a factor, but I have a friend that has an older hp that he would like to upgrade if possible. This possibly could help. Thanks.
