CMOS Battery State Low
There is a battery in the system which is used for
storing the CMOS values. This battery appears to be
low in power and needs to be replaced.
CMOS Checksum Failure
After the CMOS values are saved, a checksum value
is generated to provide for error checking. If the
previous value is different from the value currently
read, this error message appears. To correct the
error, run the WinBIOS Setup Program.
CMOS Display Type
The type of video stored in CMOS does not match
Mismatch
the type detected by the WinBIOS. Run the WinBIOS
Setup Program to correct the error.
CMOS Memory Size
If the BIOS finds the amount of memory on the
