Why am I getting the BIOS ROM checksum error?

Hewlett-packard / Pavillion a 6010 e

Specs: Windows 7 vista home basic, 256 mb ram
The ...ATAPI device ... message and found CD ROM, try to Boot from it... fail message. The HP recovery cd doesn't work. Can I fix this problem?

A BIOS ROM Checksum error is serious and very often fatal. You would normally only see it after a failed BIOS update. Have you done that recently?

Unless you can get the computer to boot from an external device, and with a corrupted BIOS that is unlikely, the only solution is to replace the BIOS chip.

Whether you can do that is dependant on whether the chip is socketed or soldered onto the motherboard and the computer manufacturer can supply the necessary chip.

If the chip is soldered and if this is a laptop, highly probable, then the computer is due for the trash can.

Cathy don't fret if you have precious data, photos, videos, movies, document or music etc on the computer. It is possible to retrieve it all.

Are you sure you've only got 256 meg of ram in that thing? You need more.

You start off by asking about a checksum error--sometimes cured by replacing the cmos battery and then going into bios setup and correctly setting date and time--and then describe a booting problem. Anyway that booting problem sounds like a bad cd drive or maybe bad cds.

This is a desktop HP Pavillion model a6010e CTO but it is about 6 years old. I did not have a failed bios update. I upgraded the memory several years ago but have never replaced the cmos battery.

A checksum error or bad cmos battery shouldn't prevent you from booting from a working cdrom with a good, bootable disk. You just need to make sure the cdrom is the first boot device in cmos/bios setup.

After 6 years it's probably a good idea to change the cmos battery. They're just a few dollars at radio shack or similar places.

Try another battery for $5.

If you are correct replacing it, loading the defaults and resetting the time should get you going, if that's indeed the problem.

To err is human but to really screw things up, you need a computer!

What Dave is saying is true, if the error was Bad CMOS checksum. But it isn't, it is bad BIOS ROM checksum, a completely different thing.

You cna try a new battery, you have nothing to lose except a few dollars, but it wont solve a BIOS ROM problem which is Read Only Memory.

Thanks I will try the new battery. The bios chip is soldered so if that doesn't work it is trash can time.

I doubt the bios chip is the problem. Try the new battery and let us know how it goes. Once installed you'll need to go into bios setup and set the date and time and likely the boot order. The other default settings may be OK as they are.

I still think there may be a problem with the cdrom or the disks you're trying to boot from.

Replaced the battery but this didn't help. I get the message Detecting IDE ATAPI device... Found CD ROM, try to boot from it...Pass The screen remains black but nothing happens. Is there a way to check the CD ROM drive?

Replacing the battery and updating the bios settings hopefully would have fixed the checksum error. The problem with the cdrom is something separate.

Maybe a little more history of the computer would help. According to specs for the Pavilion a6010e, it came with either a combination cd burner/dvd player or a dvd burner. The bios screen message is saying it's finding a cdrom. Is whatever optical drive you're trying to boot from the original one that came with it? You mention trying to boot from a recovery disk. If that disk is a dvd and you've got a cdrom then it won't boot.

Also, what happens if you don't try to boot from the cdrom and just let it boot normally from the hard drive? Does it go ahead and go into windows or is there some problem with windows (since you're attempting to boot from the recovery disk)?

The best way to test the cdrom would be to see how it works with disks while in windows. The other alternative is to replace it with a known working cdrom.

It is the original cdrom drive that came with the computer and a recovery cd that I purchased from HP. I have previously used the recovery cd and it installed properly with the cdrom drive.I cannot get the computer to reboot from the hardrive. Windows does not load. All I have is a black screen with the original error message .

'. . . the original error message.' You mean the message about failing to boot from the cdrom? The checksum error doesn't show anymore, right?

So it doesn't boot from the hard drive. When you try booting from the hard drive do you get any error messages?

If you can't boot from the cdrom then it's bad or the disk you're using is bad.

NO, I Continue to get the "Bios Rom checksum error then Detecting IDE ATAPI device... Found CD Rom, try to boot from it... Pass " but nothing happens the screen remains black and the disk does not load.

And you set the correct date and time in bios setup after changing the battery and it's now keeping correct date and time?

If the answer to the above is ' yes' and 'yes' then it's a more serious problem as Stuart first suggested. You should try clearing the cmos. That probably won't fix it but you should try it anyway. You need to locate the 'clear cmos' jumper on the motherboard. Then with the power cord disconnected, jumper it from the standby position (where the jumper is at now) to the clear position for a few seconds. Then place it back in the standby position. Plug the power cord back in and start it up. Enter bios setup and set date and time. Save those settings, exit bios setup and let it reboot and see if anything has changed.

If that doesn't fix it an attempt at a bios update would be next. I haven't checked the support page for that model to see what's available. Does the computer have a floppy drive and does the computer you're on now have one? (Bios updates, especially under your circumstances, are easier to do using floppy disks.)

No and no, I am not able to access the bios setup so I have not reset the date and time. Will clearing the cmos allow me to do this? The computer does not have a floppy drive. The computer I am using now doesn't have a floppy drive either.

Under normal circumstances the bios will recognize the setting have been cleared and on the first startup after that it will suggest you go into bios setup. I don't know if that will happen for you. It's going to depend on what the damage is.

I'm not sure how to proceed. It doesn't seem you have any device to boot from. I still feel the cdrom is bad. The bios gets to the 'boot from cd' stage and at that point it's pretty much done its thing and hands off to the boot up process.

It's not booting from the hard drive either. You probably have a 'boot from USB' option in the boot order but apparently can't get into bios setup to move its boot priority--if that were needed. There may be a separate option showing on the startup screen about pressing a key for the boot options. If so try that. After that the only possibility I can see is to set up a bootable flash drive with the bios update files on it and hope it boots from there and that the update fixes the problem.
