Hi again.I have recently bought a used desktop for personal use.It work well for some time.Recently when I start the computer,the computer does not go to setup.However,it displays a message like this:

Boot lock Compatible Version Ver.016
Please do not insert any disc into CD-ROM or Floppy drive
if you want to recovery with an USB device.
Bad BIOS checksum.Starting BIOS Recovery
Checking for floppy....
Floppy not found!
Checking for CD-ROM...
CD-ROM not found!
Checking for USB Device...
USB Device not found!

It continues on and on with checking with floppy, etc.I cannot go to setup or do anything.What can I do to remove this annoying message?Thanks in advance.

I cannot go to setup or do anything

I assume that this means you tried to enter the BIOS setup?

With power off and unplugged from the wall.
Remove the 3.3vdc battery. It is a silver flat battery about the size of a watch battery. Leave it out for about 10 minutes.

Better yet replace the battery. They are about $4.00 US.
The "bad bios checksum" is referring to a bios problem. The battery is meant to hold those settings.
So either the battery is bad, or worse (I have had this a couple times), the main board is bad.

Replacing the battery should allow the computer to load its default settings.

Hi guys...

Do you mean the motherboard is an ASUS Maximus Formula? If that's the case, it shouldn't be the CMOS battery...the Maximus boards haven't been around long enough that you should run into a dead battery unless the battery was defective from the git-go.

There is a Clear CMOS button on the bottom of the Maximus boards that allows one to reset the BIOS settings to default settings. Have you tried pressing that?

The file it's asking for is a BIOS update. Updating the BIOS on most ASUS boards is pretty painless using their EZ Flash utility.

Some generic instructions can be found HERE. For more specific instructions, consult the owner's manual that came with your board.

Its still not working.I have gone to the website and found the bios update.However,when I renamed it to P5E.rom and put it inside my thumbdrive.

It displays this:

Boot lock Compatible Version Ver.016
Please do not insert any disc into CD-ROM or Floppy drive
if you want to recovery with an USB device.
Bad BIOS checksum.Starting BIOS Recovery
Checking for floppy....
Floppy not found!
Checking for CD-ROM...
CD-ROM not found!
Checking for USB Device...
USB Device found!
Reading file "P5E.rom"
File not Found!

One more question:I have read the thread and they said that I need to go to setup to update my bios.However,I can't even go to my setup due to my boot lock.What do I do?
