Error Messages
This chapter lists error and warning messages, alphabetized by message text. These are
messages generated by the BIOS and MS-DOS that may be related to your hardware
configuration.
CMOS checksum invalid
Something in the nonvolatile CMOS RAM is incorrect. Run the BIOS setup program to
determine what is wrong, and correct it. If the error occurs repeatedly, the EPC-6A’s
battery has failed. This error is available only on a VGA screen.
CMOS RAM error, check battery / run setup
Something in the nonvolatile CMOS RAM is incorrect. Run the BIOS setup program to
determine what is wrong, and correct it. If the error occurs repeatedly, first try
reinitializing all CMOS RAM parameters. If the problem still occurs, the EPC-6A’s
battery has failed. This error is available only on a VGA screen.
EXM configuration error
The EXM installed (or not installed) does not match the configuration information in the
novolatile CMOS RAM. Hitting any key will allow you to continue, but doing so may
cause problems later if software tries to use the EXM. To correct the problem, enter the
remote setup program, change the information on the setup screen and reboot. This
message is logged to the NVRAM.
Real time clock error - run setup
The battery-backed TOD clock is incorrect. Run the BIOS setup program to determine
what is wrong, and correct it. If the error occurs repeatedly, the EPC-6A’s battery has
failed. This error is available only on a VGA screen.
Seven-Segment Display Codes
The following list shows the two-digit codes displayed in the seven-segment display when
a catastrophic selftest failure is detected. The two digits display repeatedly in the
following way: first digit, pause, second digit, long pause.
