After upgrading your system BIOS with an update from the manufacturer, you receive a CMOS Checksum error after rebooting.
What should you do to clear the error?
1. >>Reboot the PC, enter CMOS setup, and check and save CMOS settings.
2. Press the ENTER key and turn off the computer before all data is lost.
3. Replace the BIOS chip with a new one from the manufacturer.
4. Reboot the PC and try to flash the BIOS again.
Explanation : After upgrading the BIOS on a motherboard, the new BIOS will likely take up more bytes of ROM than the replaced BIOS. The difference in the BIOS image file byte count is detected by the system as a checksum error. CMOS checksum errors require that you enter Setup, check and save your settings, and exit Setup a second time.
You should not reboot and flash the BIOS again because reflashing the BIOS would most likely result in the same error.
You should not replace the BIOS chip with a new one. A checksum error does not indicate a failure of the BIOS hardware.
You should not press the ENTER key and turn off the computer to avoid losing data. A checksum error will not cause any loss of data.
