Hello, I went into my bios settings and did something wrong now when I start up my computer it takes me to the mi bios megatrend screen at the bottom of the screen says driver bad press f2 to resume f1 for setup F12 for bios menu how do I get it to start up normally again

you will have to go to your computer manufacturers site and select 'support' and then 'BIOS and Drivers'. You should be able to download the latest legit bios...
If I had your motherboard model or computer model, I could find it

american megatrends is the Bios (Basic input output system)
It is being displayed because you may have turned off the fast boot up mode if your operating system is windows 8 or windows 10.
https://www.asus.com/au/support/FAQ/1015899/
explains how to turn on fast boot under windows
This will then not display the post part of the bios at start up.
what is post ? you may well ask

It's best to simply replace the entire Mother Board than try to replace the BIOS. Replacing a Mother Board vs replacing a BIOS is way easier.

Your current BIOS MIGHT work if you can find a flash file for it, but you have to be careful. If the BIOS your flashing isn't in production it's usually only PATCH flash file, to fix a problem with a BIOS, not upgrade it. And if you use the wrong flash file, it will TRASH your BIOS!

The BIOS, which is a chip, is usually micro-soldered to the Mother Board with high precision, by a robotic arm, and not easily removed or duplicated. The exception is if you happen to have a BIOS chip, that can be replaced, in a socket, but this is unusual instead of common.

The best source for BIOS info such as you are looking for is the American Megatrends Website itself at: AMI American Megatrends Inc Aptio (compatible with Windows 8) however their website is for the Mother Board manufacturer so you can't buy the BIOS as a consumer, but through a reseller, AMI Office, Authorized Representatives, etc (AMI American Megatrends Inc How to Buy).

You can however, buy a replacement Mother Board with a BIOS already installed on it (that's the way you usually buy them - with the BIOS pre-installed on the Mother Board) that's PAE, NX, and SSE2 and whatever else you want compatible. A great website to find computer parts and kits, new, refurbished, out of box, etc is the Tiger Direct Website at: TigerDirect com Electronics Tablets Phones Office Supplies Video Games. Just search for BIOS to find your specs, then check the bottom for possible best Mother Board kits to replace the one you have now. Hope this helps. :-)

select the first boot option and press enter

This will happen when either you have an incorrect setting in bios, or you have a bad component. With the beeping I would have to guess it is your internal ram memory. Easily replaceable.

Have you tried starting it in safe mode? Or the settings on your bios might be incorrect, it might be set to boot off a cd or something..

As the computer is booting watch the screen it'll say something akin to
press F10 or DEL to enter setup F2 to enter the boot menu.

It will be the F10, Del and sometimes F12 that you're after.

Be careful to read the instructions for the bios, make absolutely sure you
are confident and correct in changing the settings.

If you're not sure quite what you've done, exit without saving changes.
Then try again.

it looks like you have something extra connected that is the bios manufacturer, if you have a new external hard drive connected to it try to remove`it and connect it after your windows starts up in other scenario your computer try`s to detect a hardware that does not respond properly

Press and hold the F2, F12, or F8 function key (one of the three at a time) after jhearing a single beep following a restart. One key (usually F2) will allow you to change the BIOS settings. (If the computer boots normally, restart it again and try the next function key.)

BE CAREFUL. Don't change anything you are not sure of because doing so can make your computer inoperable!

You will eventually get to the BIOS settup utility. You will have to use the keyboard to navigate to the setting that disables the splash screen. (You may have to enable something like "detailed boot report" or "OEM settings", depending on the computer.)

My American Megatrends (AMI) BIOS has a "BOOT" section that contains a "Full Screen Logo" setting. I "Disabled" it to do what you want to.

Incidentally, the splash screen doesn't really slow the boot process much, since you are simply substituting a static picture for the BIOS boot information.

Hi,
The compute post tests the computer, insuring that it meets the necessary system requirements and that all hardware working properly before starting the remainder of the boot process.
1 Short Beep, Normal POST, computer is okay. No problem. 2 Short Beep, POST error....floppy drive 0 error and keyboard error........This can happen because there is something wrong with your floppy drive, something is causing your computer not to detect it or that you simply don't have one.
Check your floppy cables and connections first to ensure that they are connected properly, if they are then you may have a burned out controller on your motherboard, a bad floppy cable or drive, or your motherboard may be faulty. If you don't have one you can disable the message in your computers BIOS. To get to the BIOS screen, during boot up at the bottom of the screen it will say something like "press F2 for setup" or something along those lines. That will take you to the BIOS screen. In the settings there should be options like first boot device, second boot device, and so on... change the one that say 3.5 floppy to something else such as your CD rom.That will get rid of that message.
Keyboard error or no keyboard present shows up when your computer can't find your keyboard or there is something wrong with it. Replace with new keyboard. Thank you
