BIOS Beep Codes
If the BIOS detects a critical error condition while running the Power On Self Test (POST)
code, it may halt after issuing a beep code and attempting to display the error code in the
upper left corner of the screen. The audible codes consist of patterns of beeps and pauses.
If this occurs, you should contact your supplier for technical support.
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.
System hangs during boot
process (Master LED on;
RUN LED off)
VMEbus has no Slot-1
controller providing bus
timeout.
You are probably loading an
expanded memory manager (for
example, EMM386.EXE) in your
CONFIG.SYS file. This can cause
the system to hang if:
• There is no Slot-1 controller
• The Slot-1 controller is not
providing the proper bus timeout
• The Bus Grantbus jumpers are not
installed.
System does not talk
across VMEbus.
The VMEbus backplane may
not be jumpered correctly.
See the section Installing the
VMEbus Backplane Jumpers
in
Chapter 2.
More than 1 master may be
set to provide Slot-1
functions.
Make sure that only 1 system is
configured as the Slot-1 controller
and that it is the left-most system in
the chassis.
There may be no Slot-1
controller providing bus
arbitration.
Determine if the system is in the
left-most position and that the Slot-1
controller jumper is set.
EPC-8A or subplane may
have bent pins.
Remove the EPC-8A and the
subplane and verify that no pins are
bent. Then reinsert the subplane
and the EPC-8A.
VMEbus interface failure. Call RadiSys Technical Support.
