I am working on an older Windows 98 computer. When I turn it on, the screen shows the bios manufacturer and version number, identifies the primary and secondary drives, then posts the following error message:
CMOS Checksum Error - Defaults Loaded
Press F1 to continue, DEL to enter setup.
Pressing either key does not work, as a matter of fact the lights on the keyboard flicker, but none of the keys will work. tried pressing Cntrl-Alt-Del to reboot but nothing happens. I replaced the cmos battery with one that I know is good and get the same results. I cannot enter setup or the boot menu to diagnose the problem. I think there is something wrong with the PS2 port that the keyboard is plugged into, because I know the keyboard works in another computer.
There is only one PS2 port, the other port is a larger 5 pin port, normally used for a mouse. Could this 5 pin port also be used for a keyboard, and maybe I need a keyboard with a 5 pin plug to make the computer boot?
Or . . . am I diagnosing the problem incorrectly?
SOURCE: cmos checksum erroe defaults loaded
press del to enter setup.then choose default bios setup. then save and exit.pc will restart.
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.
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.
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

I do not have the manual, and the make and model of the computer is not known. I think it was a custom build. The only thing listed on the motherboard is MB - 8500TDU-A ver 1.1.
