LED Description

Power LED (green)

blink Bootup, loading Flash ROM and starting ppc_uartd.
blink slowly Shutdown timer has been activated. Box will shutdown soon.

If ppc_uartd does not start for some reason (or is started late due to hardware/software issues), the Power LED will continue blinking. After five minutes the DIAG LED will continuously blink 6 times (hard drive failure) and then shut the box down.

*1 If your boot kernel is located on your hard drive, and your hard drive fails, you will get the Flash ROM error instead of the hard drive error because the boot kernel could not be loaded.

*2 It may be possible to recover from a Flash ROM error by pulling out the power cord and trying to boot again the next day.

*3 Users have reported getting this error when the hard drive already has a Linux partition on it. The solution appears to be to simply reformat the hard drive.This might also happen if the PSU does not provide enough power for the hard drive, or if the hard drive takes too much time spinning up.
