Common Error Messages
This section contains a summary of 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.
BAD OR MISSING COMMAND INTERPRETER
Problem: The DOS operating system cannot find the Command line interpreter.
Solution(s): Either COMMAND.COM is not present at the specified (or default)
directory level of the boot disk or the “SHELL=” statement in your
CONFIG.SYS lists the file incorrectly (wrong directory or
misspelled).
CMOS CHECKSUM INVALID
Problem: Something in the nonvolatile CMOS RAM is incorrect.
Solution(s): Run the BIOS setup program to determine what is wrong, and correct
it. If the error occurs repeatedly, the EPC-5A's battery has failed.
CMOS RAM ERROR, CHECK BATTERY / RUN SETUP

Solution(s): Run the BIOS setup program to determine what is wrong, and correct
it. If the error occurs repeatedly, the EPC-5A's battery has failed.
