So it appears as if my BIOS is corrupt.

Upon boot I get this message

Award BootBlock BIOS v1.0

BIOS ROM checksum error
Detecting floppy drive A media
INSERT SYSTEM DISK AND PRESS ENTER

Can't get to bios, or anything. This is the first and only screen I see.

I tried making a dos boot disk. But honestly I have no clue what I am doing with this kind of stuff. I did get the bios download off the manufacturers website. But it says not to flash it with a floppy disk. I'm pretty much at a dead end. Any and all help is appreciated.

Here is the website where my motherboard drivers are. This should help with the model number etc.

What are your system specs?

I think you should try unplugging the floppy drive and trying to boot.
 
Here are the specs:
AMD (Sempron, I think)
2GB DDR Memory
250GB Sata HDD


The motherboard is not that old, this machine was rebuilt about 2 years ago.

I tried disconnecting the floppy but then I get the same error, along with a "Floppy Drive Error" and a series of never ending beeps.

Also tried clearing CMOS, and removing the BIOS Battery for a period of time, and then replaced it. Neither of those changed anything.
 
Check for a loose or bad cable going to the hard drive. Or you may have a bad hard drive altogether.
 
Just flash from floppy. I don't know why they are telling you not to. Further in the doc they are running commands from A:\ :P

1. Know your model number
a. Open your case and look for the MS-XXXX number on the motherboard between the PCI slots, also check the version number that is written there as well. (Some motherboards are named like K8N Diamond; make sure you have the right version number)
b. Boot up your system & take a look at the top left screen during POST, you should see something like “W7100NMS V1.1 021705” This means the board is MS-7100 with BIOS version 1.1
Hint: Many systems are clearing this message very fast, the bios version is then unreadable, and you can either press “PAUSE” or disable the “Quick Boot” in the BIOS setup.

2. Download the BIOS that matches your motherboard AND version number (some motherboards are named like K8N Diamond; make sure you have the right version number). BIOS can be found according to the CPU type of your board like if your CPU is AMD 939 type then look here
http://www.msi.com.tw/program/produ...st.php?kind=1&CHIP=68&NAME=Socket 939 (AMD K8)
if you cannot find the BIOS that matches your board, try here http://www.msi.com.tw/support/bios/more.php

3. Extract the BIOS-archive that you have downloaded by double clicking to c:\test

4. Boot your system from a Win98 or WinME boot-floppy.
How to make boot floppy in case your don’t have it ready:
For Win9X, You can type [C:\ format a:/s] from the DOS prompt.
For WinME, You can make a boot floppy from control panel--> add/remove program-->make boot floppy. Remove autoexec.bat & config.sys file if there's any.
For Win2000, there's no way to make boot floppy, so you have to either use Win9X or WinME boot floppy.
For WinXP, you can make a DOS boot disk. Go to Your Computer, right click drive A:, select Format, select copy system files.

5. When you get the A:\ prompt, type the following sequence:
C: <enter>
cd\test <enter>
C:\test> awdfl865 BIOS file
(To save or not to save old BIOS is the user’s decision)

6. Reboot your system when prompted

Perhaps a bad battery in the motherboard? I've gotten a BIOS checksum error from that. If it's that, that's an easy fix.

A dead battery can give you a CMOS checksum error but it shouldn't be a ROM checksum they are similar looking but very different error messages.
