Two Long Beeps are Heard and an Error Message Is
Displayed on the Screen
These messages are of the form:
BIOS (<xx>) : <text>
where <xx> is an error code and <text> is a short description of
the error.
If you get an error message that does not have the format above, then
it is most likely a message from an option PROM installed in the
system unit.
If the error is in the keyboard, the program continues to execute after
a short delay. Otherwise this prompt is received:
Press
Fl to continue
Pressing the F1 key allows you to bypass the error condition, but
does not correct it. Steps must still be taken to correct the error.
You should therefore:
1.
Insert the Setup and Maintenance diskette in diskette drive A
(drive 1).
2.
Press the F1 key.
3.
Run the Setup program. Refer to the section Using the Setup
Program later in this chapter.
Below follows a list of possible error codes.
BIOS (16) : Option PROM <xxxx>H
r
bad checksum
The option PROM located at the specified paragraph contains a bad
checksum and may be faulty.
BIOS (17): CMOS clock to slow
The system board CMOS real-time clock has stopped or is too slow.
Most likely this is due to wrong contents in CMOS memory cell
OAH (should be 26H) or cell OBH (should be 02H).
