The actual BIOS file posted on the Gateway site for that model is the incorrect file WARNING....It is actually the Firmware Update for the DVD Player...Bad part is it will update if you force it and override the bad checksum feature in the BIOS Update process. I know, I am currently attemptiing to locate the proper file after incorrect updating by another "professional" tech service that wasn't so professional and didn't realize the Gateway site's mistake myself.

Bios rom checksum error, boot block bios vI.0


Error BIOS ROM CHECKSUM - SYSTEM HALTED.
Cause Bad Hardware
Solution Unfortunately this indicates that your computer BIOS ROM chip or Motherboard is physically bad. It is recommended that you contact your computer manufacturer or take the computer into local service center for repair.
If you wish to repair this issue yourself the motherbard will need to be replaced.
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.

The BIOS ROM chip on the motherboard is probably faulty. It could also be another component on the motherboard.

You should make sure that all of the BIOS settings in the system are correct, by rebooting the system, going into BIOS setup and double-checking all the values hopefully against a recent


If you have reset the CMOS memory you need to go into the BIOS setup screen and reconfigure the BIOS. To do that you need to press a key while the computer is booting. Usually F2 but can be other keys. It should tell you on the bottom of the first screen which key to press to enter BIOS setup.
If you don't know the settings the should be one for optimal defaults - use that one. You will also need to reset the time and date.
Save, Exit and re-boot and everything should then work.

During the boot process you will see on the screen a certain key to press to enter setup
Press and hold that key 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
You will also need to set the time and date

In the main or system setup screen you should be able to see the date and time Using your arrow keys navigate to the date and change the date. Once highlighted on the month, day, or year, press your arrow keys or your page up / page down keys to change the date.
hope this helps you

Reboot, go into the BIOS despite the error message then lower some settings below default values. Save and restart - if you got the same error message again then the BIOS chip is no longer powered correctly, the motherboard is dead.

Hi.

The most probable reason you are getting the bad checksum error is you have to set the date and time because you have cleared the CMOS and reset the BIOS.
You should also get a message that says press F1 to load defaults or press a certain key to access setup. Access setup (BIOS) and set the date and time. That should take care of the bad checksum error.
Another good idea is make sure the motherboard battery is not dead either.



Regards.
