Real-time clock (RTC) and CMOS RAM
A real-time clock component provides Real-Time Clock and Calendar functions. The circuit contains 114 bytes of
battery-backed-up CMOS-static RAM memory used for clock functions, and for storing the configuration
information (e.g., the number of diskette drives, the amount of system board memory, etc.).
The CMOS RAM memory is backed up with a non-rechargeable battery that has a considerable lifetime.
However, should the battery begin to fail, the following message (and possibly others) appears on the screen
during the power-on test:
BIOS (27): No battery for CMOS clock/RAM
Press <F1> to continue, <Ins> for set-up mode
If you receive this message check your date and time values in SETUP. It could be that your Time and Date
parameters contain the wrong values, causing the above message to occur. If this is the case, enter the correct
values, save the changes, and this message should disappear.
