Checksum error of BIOS ROM MSI MS-7005 motherboard!

Asked By 10 points N/A Posted on -

My MSI MS-7005 motherboard (651M-L/650GM-L Series) got a problem.

BIOS ROM was seemed to be removed by CIH error. And I can not boot my system. Therefore,I prepared a MS DOS bootable floppy disk and made autoexec.bat which will re-write automatically the BIOS ROM into the motherboard and tried to boot it but the following error appeared on the screen.

BIOS ROM checksum error

Keyboard error or no keyboard present

Detecting floppy drive A media…

Drive media is: 1.44Mb


There is no problem with the floppy drive. I confirmed it on another system.

There can be multiple causes of this kind of problem, first of all check whether your motherboard’s boot sequence is set, like if you want to boot from floppy drive you must have set floppy drive as first booting device.

Besides that this type of error can be occurred if your machine is trying to boot from HDD, if it is so, then probably HDD is not present that’s why this type of error is being occurred. Again to minimize this problem set floppy drive as your first booting device to boot from floppy drive.

If you feel you have made too much irrelevant changes in your Bios settings then its better to restore Bios to default settings. Then again set boot sequence and boot from your desired device. Best of Luck!
