Help, Help please!! Bios Rom Checksum error detecting floppy drive A media

I have a compaq presario S6500NX. When I start it up, it says bootblock and then Bios Rom Checksum error, followed by Detecting floppy drive a media.
I was doing a little reading about this and it said that most likely the Bios is corrupt or could be bad. It says to load the bios flash on a floppy. Problem is the floppy on the computer I am working on is broken.
Is there any way to load the bios flash onto a disc as it reads the compact disc first in the order of booting or am I going to have to get a floppy drive to replace the broken one?
Does a corrupt bios sound like the colprit to you?
Any information would be appreciated and thank you ahead of time.

 

It's likely that your busted floppy drive itself is causing this error.

If you go into your bios settings and uncheck it from the boot sequence and also uncheck the "search for other boot devices" it should go away.

Older machines would throw a fatal error if the floppy drive was missing. May be a hangover from those days.

 

I cannot get into bios or anything, as soon as you turn it on, there are no options, no F anything, just straight to what I said before, so does that mean that the floppy itself could still be causeing the problem or is it something else being that there is no other option?

 

Is there a program that I need to flash a bios or can it be done manually from a working computer to a disk or cd? If need a program could you please provide a link, would be appreciated greatly, thank you.

 

I have tried everything that I know, please help. I installed a floppy drive, created a system disk and sometimes when it feels like it it loads it.
I created a bios update diskette, but do not know how to access it when I pull the system disk out. How do I get it to access from the dos prompt A drive?
Sometimes it will not even recognize that my keyboard is hooked up, and the num lock key never lights up.
The power button is somewhat bad, have to hold it in from the back to turn the power on most of the time.
Is the BIOS chip completely gone or is there something that I am overlooking, hopefully.
I was told that when the Bios is corrupted you need to have it flashed, is that something that can be done with a disk or does it have to be taken to a service center?
I just cannot seem to figure this out and have no idea where to turn to now.
I unhooked everything but the keyboard, mouse and monitor and when I turned it back on it went ballistic wanting the A drive hooked back up. I installed new compatible ram and got the same thing.
This computer is the dirtiest I have ever seen the inside of one. I am working on it for a friend and I think it is cleaned never. The dirt was caked on and I cleaned it out as best I could.
If you have any ideas or suggestions or hopefully know that is the matter, please help I am at a dead end here. Thank you
