Help :-(

Hi I installed Suse 6.4 on my Power150 It was working fine until today... All I did was shut the server down....unplug the server and the external drives...plug everthing back in and turn it on.... The Suse system did not want to boot :-( I looked at my BootX screen and my kernel args were gone!!! Does anyone have any basic kernel args that I could try? There is absolutely NO help on the Suse Site Cheers MARCUS
