Hi, You have to configure your CMOS/BIOS. On powerup, press "Del" or whatever key is necessary to enter CMOS/BIOS Setup. Once inside, verify that 1.44 FDD is enabled/checked that is if your PC has got one and set to None if none, thereafter Save & Exit. Verify also that the FDD is connected to a power connector from the PC's power supply. Likewise check that the flat cable is securely connected. It the FDD shows a continuous light, it may be that the flat cable was wired/connected wrong, if this is the case, simply reverse the way it is connected to the rear of the FDD. Hope this be of some help/idea. Post back how things turned up or should you need further information. Good luck and kind regards.

Go into the bios (do this by hitting the del, f2, or f1 key right when you turn the system on) Once you are in the bios there will be an option somewhere listing your drives (cd, hard drive, floppy drive). Change the floppy drive setting the disabled or none. save and reboot.

CHECKSUM CANNOT MOVE COMPUTER FROM A BLUE SCREEN


In order to understand what a checksum error is, it is important to first learn what a checksum is. A checksum is a redundancy check during a computer's start up process, which makes sure that the computer's data is intact and unhampered. The data is scanned and tested for accuracy, either based on how well it relates to data elsewhere or based on previous data that was stored on the same computer. Essentially, all of the bits of data in a particular document or file are added up and a number or hash is created. This number or hash can then be compared to the number or hash generated from the same file on another person's computer or at a previous time on the same computer.
When does a Checksum Error Occur?

Although a checksum error can occur at any time while a computer is comparing data, it is most commonly present during a computer's startup procedure. During a computer's start up processes, the BIOS settings, which are stored in a CMOS memory chip, are computed and then checked against the previous value. If the computed values do not match exactly, the computer warns the user with a checksum error message that the data may have been changed or corrupted between start up cycles. All BIOS programs present a different error and therefore will either continue with booting or refuse to boot until the problem is corrected.

Depending on the type and the severity of the error generated, there may be one of a variety of ways to rectify the issue. The most common cause of a checksum error during the startup process is a faulty battery that is not providing sufficient power to the motherboard when the computer is off. However, motherboard malfunctions and viruses can also contribute to checksum errors.
Other Types of Checksum Errors

Another type of checksum error may occur with any program at any time. It is usual for many programs to now provide checksum information when that program is downloaded. Using a checksum program or MD5 hash checker, a user can quickly compare the checksum of a downloaded program with the checksum that the software developer provides. This is a common way to make sure that users are downloading the proper program and that no data was corrupted during the download process. Checksum errors originating from download errors can easily be corrected by re-downloading the problematic program.

Compaq Presario 2500 stopped loading windows XP with a prompt STOP: c0000221 {bad Image Checksum} The image COMCTL32.dll is possibly corrupt. The header checksum does not match the computed checksum.


This error is not the same as a CMOS Checksum Error, which refers to corrupted values of the CMOS settings, the ones you set through the BIOS setup program. This error means the contents of the BIOS code itself are damaged.

During the boot process you will see on the screen to press delete to enter setup
Press and hold delete during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
click start control panel date and time you can make your adjustments to the date and time from there also right click on the date and time on the bottom toolbar (bottom of screen) you should see Adjust date and time tab
hope this helps you

Bios ROM checksum error (Compaq SR5237CL with M2N68-LA MB)


A BIOS checksum error can be caused by a nearly flat BIOS battery.
I would replace the BIOS battery first before attempting to upgrading the BIOS.
Some motherboard BIOS firmware is upgraded by running a program that has been copy to a DOS boot disk or the upgrage maybe done from within the BIOS setup. These firmware upgrage and instructions are on the motherboard WEB site, in your case the Compaq/HP WEB site. Make sure you select the upgrade for your model motherboard.
NOTE it is possible that if you make a mistake you could ruin your motherboard, if you are not sure seek help from a computer savy friend.

Hard Drive will not boot in Compaq Presario C700


BIOS checksum errors occurs when either the BIOS chjp is faulty or most likely the BIOS battery is nearly flat and the stored info changes and doesn't match the checksum info.
Replace the battery with a new one, leave the battery out for 1/2 hour before inserting the new battery. The BIOS will be reset to the default settings, you need to configure it again eg, datr and time etc.

Checksum error


Hi Oliver, the most common error related to the message,
(Bios Rom Checksum Error). Someone has left a floppy disk in the floppy drive. Once the floppy disk has been removed press the reset button on the PC, your windows will start normally. Next place to look is in your bios.
Open your manual to page 27.
Enter your bios & go to the title Advanced BIOS Features. Check First, Second & Third boot devices they should be as follows. Floppy disk drive, CD-ROM drive & primary hard disk drive. If both of the above are ok than try clearing the cmos/bios by resetting the cmos jumper (JP1) location on page 5. Descriptions of page five on page 6. CMOS settings on page 9.
When your system restarts re-enter your cmos & reset up your bios settings. Lastly if none of the above has fixed the error message, than remove the cmos battery & check its voltage. It should maintain 3volts. If yours' is lower than 3volts replace the cmos battery. There is one other possible fix. It’s an option not given lightly. Flashing a cmos/bios is not recommended unless all other options have failed.
