Updating your BIOS with DOS 

Thank You. I know updating your BIOS can sometimes be confusing and SCARY!

You are most welcome. Hope to have more videos out soon!

@@pjasonq can't wait!

Its normal for the filename in DOS to be shortened. Not all BIOS updates run in DOS. If it doesn't run in DOS, your next best option is to run it using Hirens Boot USB or if you already have Windows running on your PC, you can run the BIOS update in Windows.

DOS program? not too sure but Linux Mint works great for testing and getting info on each PC. I can test the GPU, WiFi connection, speakers, web cam and more all without installing anything. If you make some USB bootable drives for testing, you should have one for Linux Mint and one with Hiren's.

There's a lot going on here. Let me put my thoughts into bullet points: - I'm not a big fan of updating your BIOS with a modified ROM file because you run the risk of bricking your PC - If it was modified, there should have been some instructions that came with it such as a readme file that explains the process...I would follow that - Some exe files may not run in DOS and that could be why you are getting errors - BIOS ROMS or BIN files are usually verified before they are executed. So another reason for the error is the BIOS updater is running the ROM and it is failing verification - Have you tried running the exe in Windows or Hirens? I would try that but again I would research and triple check everything before running a modified ROM

Not sure...if it works...chances are you may not even need to do a BIOS update. In these cases I would research the manufacturer's website and google the model...sometimes people will leave instructions on what they did. Not all PCs or servers need to have their BIOS updated...good reasons to update are CPU/Memory compatibility updates, Intel Virtualization update, security updates...if those are not needed...you may not even need to worry about updating your BIOS.

You might've bricked your PC if it boots to a black screen after bios update

its helpful if I know the brand/model. The ROM is typically the main BIOS image file. That error is basically saying you are trying to update your BIOS with an older version. In many cases...if it doesn't update, it will either do nothing or revert back to the previous working BIOS

What model is your HP? I believe the G3 and higher allow you to update the BIOS directly from the BIOS. I just updated an older G2 using hirens and running the .exe bios update

@@pjasonq hello sir, i have HP probook 6560b, it is to old model 2013, i tray many ways to sulove this problem but nothing help,

​@@ghazwanalshghai3893ok...based on the age of the laptop, it may be currently using 'Legacy' Boot. Try changing the boot method to 'UEFI' and then it may work.

He legit showed how to use dos on a USB I can tell you don't pay attention

I'm not exactly sure what you mean about Win32. Maybe they are referring to making sure your drive is formatted as FAT32?

Many newer hp's can have the BIOS updated right in the BIOS...which is pretty cool. If not, my go-to is HIREN's. Just make a bootable HIREN's USB and you can run the BIOS update executable...the other obvious option is to update it right from Windows

I’m going to have to do this method I’ve tried every other way to no avail

not all BIOS updates can run from DOS. When you download the latest BIOS, check to see if there are any instructions...that will give you a clue as to what the preferred method is to update the BIOS. I'll be honest...most newer systems have a BIOS updater either within the BIOS or from the boot menu. Check that first as I'd likely prefer that method over the DOS method. Dell has a BIOS updater right from the boot menu and hp has a BIOS updater inside the BIOS on most PCs from 2015 onwards.

There is no option to do it within the bios and the windows is working my issue is that the keyboard works in bios only not in windows. It's a Dell XPS that had windows on and now has windows 10 but the USB doesn't even work so I thought let me try another bios.

​@@pjasonqby install instructions it does say that it is ms dos compatible but doesn't run so thought maybe I'm doing something wrong

@@richardbraun6011If I were you, I'd try re-installing a fresh copy of Windows OR use the 'Reset this PC' tool in Windows 10 and do a system reset. I've seen this issue before and its a Windows issue not a BIOS issue. Updating the BIOS is a good thing to do but it will likely not fix your current problem

some BIOS updates can be different depending on the manufacturer. Sometimes the manufacturer will include a readme file or instructions to go along with the update. I HIGHLY recommend reading these instructions as they were written by the developers and some updates are very specific with the file system on your USB, the name of the image, etc. Some models may even have two different BIOS versions from two different motherboards which can add a LOT of confusion...that is why I always read the instructions 2-3 times before running an update.

I'm not sure...as far as BIOS updates go...Lenovo BIOS updates can be on the tricky side. I've bricked a Lenovo Tiny PC once and I was following Lenovo's instructions. My recommendation would be to load up Windows 10 or 11 and then use Lenovo's tool to identify your device on Lenovo's website and then allow it to detect and update the drivers. During this process it should also update the BIOS. You'll know by watching the updates and waiting for a prompt to restart the ThinkPad

I'm not sure what you mean...just hitting the tab key on the keyboard I suppose.

It could be that Windows assigns the drive letter G because there may be other drives in your system. For example if you have an internal SD card reader...those can show up as multiple drives (one for each type of card) even if nothing is in the card reader. At the end of the day if we are talking about updating the bios in DOS...the drive letter is not really important...what's important is that you can access the files and folders on your USB drive that you booted from.

downgrading the BIOS can be tricky and sometimes not possible. So let me get this straight...the newer version of the BIOS doesn't support a CPU that was in the previous versions? I've never heard of that. You may want to contact the manufacturer and ask them.

What I would do first is go back to the gigabyte bios and see if they have a BIOS flash utility within the BIOS. I know most gaming motherboards have that. I don't think I've ever used dos when flashing one of those boards

@pjasonq Thanks for the reply. I previously used the Q-flash utility but it said file is out of date, and the efiflash application had issues with a 64bit O.S so it wouldn't launch. (I then threw a 32bit O.S win10 on a spare drive and it still wouldn't launch). Then I tried your method. Now however, I just used a gigabyte utility called @bios. This worked great, no issues so far and the upgraded cpu now boots to desktop (it kept going through a boot loop previously, power on/off every 5 secs). So job done 👍 Thanks for the speedy reply, appreciate it 👍

I'm glad it worked. There's always a 'moment of truth' when you run the flash update and watch it reboot for the first time. I like your username ;-) @@VeganBytes
