You must have a faulty floppy disc unit, you need to press F2 or Del to get into the bios and check the time and date if they are wrong then the cmos battery needs changing.

My computer can not boot -BIOS ROM checksum error

to be honest if you have tried to re-flash your bios, and it did not work you still either have hte wrong version or the disc drive your using to flash it from is faulty. try another floppy drive/disc and try again. if that dont work. to be honest it's not worth getting it repaired just go out and spend £30-40 on a new mobo. sorry i'm not more helpfull but i dont believe it's worth spending that much time and effort on an old system like that with this kind of problem. good luck to you. let me know how you get on ok.

My cpu won't boot

Is there a disk in your floppy drive?
Do you use the floppy drive at all? (Most people no longer do)

If you don't, unplug the power, open the case, disconnect the floppy drive.
Plug it back in, power it on, and go into the BIOS setting screen (depending on the computer, there are different things to do, like hit the DEL key, or F12, or F2, or ESC etc)
Once you are in the BIOS screen, disable the floppy drive detection, save it and try booting again.

It sounds like your floppy drive has gone bad. By removing it, and disabling it in the detection, you can get deeper into the problem (if there is one after that)

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.

Good luck Oliver!

Biostar P4M900-M7 SE BIOS ROM Checksum Error

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.
