0000 System Board
error
POST has detected a failure limited to the system board internal
functions.
To verify this error:
1. Reboot the NetServer.
Skipping this error message and continuing may result in
unstable behavior, or a system hang during the boot process.
2. If this error continues, the system board may need to be
replaced. Contact your service representative.
0010 BIOS problem The PC configuration has been lost, cleared, corrupted, or has not
been initialized. When the HP NetServer remains unplugged for a long
period of time, the battery will discharge and not provide enough
current to keep the CMOS memory powered.
To correct this:
1. Verify the battery is properly inserted.
2. If necessary, replace the battery as described in your user's
guide.
3. Run the Setup Utility to re-configure your NetServer.
