BIOS ROM checksum error

TRY CLEAR CMOS IT CAN HELP.

your hard disk is disconnecetedor loose . pls check the hard disk power cable & IDE or SATA cable. Then check BIOS hard disk detected or not if hard disk is not detected your hard disk is faulty.

Hai, That message dosn't sound like an error. i suspect the ram is faulty/incompatible and the pc won't boot because of it. 
Change back to the old ram and reset the bios (jumber on the motherboard)

it means your boot sequence is first booting your floppy drive or your hard disk is not detected.i think you should check the cmos set-up.you can set it by pressing delete while the pc is booting.disable floppy drive seek.also the boot sequence.the os installed is maybe corrupted, is also one of the problem. refer to the manual if you have.

Hi there.
Try clearing the cmos
<<<<< you will see in the picture a plastic jumper (in this case coloured green), move it to the other position and hit the on/off button, then put it back in its original position and power up the machine again. Hopefully the issue will have been sorted. If there is no jumper remove the battery for an hour and make sure the power cord is removed from the back before you clear the cmos

Good luck and thanks for using Fixya!!

Do you get video? If so then it could be a stuck key on the keyboard.

Do you get no video? If so then reseat the RAM.

You can try flashing/updating the BIOS if nothing works.

The bios upgrade procedure stopped at half , leaving the bios corrupted. The computer now cannot do a regular boot procedure, this is the reason why it cannot recognise some device. If you are still able to boot from floppy, you can restart bios upgrade procedure from floppy. Just download floppy version upgrade and re do setup. Even if you do not find latest bios version, just download a floppy upgrade that is working, so that you can restart your machine regularly , and then do the update to latest version.
If you are not able to complete the bios setup, the only way to fix your motherboard will be flashing the CMOS chipset with a chip programmer device that will reinstall bios straight into cmos chipset.
You can have this done at the service point, in this case consider also replacing your motherboard.

Hi Faster Fester. You don't need to install the new BIOS.

You get the checksum error just because you're CMOS battery have run out. Just try to replace the CMOS Battery and you're problem will be solved.
