[Ham-Mac] Blue Screen iMac

[Jerry Rheinschmidt]

Hello all,

I had a power outage yesterday and now my iMac 266 Mhz blue and gray 
desktop computer comes up with a blank blue screen (no 
icons/desktop).  I followed all the procedures listed in Apple 
support knowledge database and it seems that I have a file directory 
issue using fsck. It says "overlapped extent allocation" (file 
841318d).  How do I fix this problem?  I have tried booting up with a 
Mac OS 9 cd but that doesn't seem to work either.  The happy Mac icon 
appears on the screen but it just sits there and doesn't come up with 
the desktop screen.  Please respond to my email address rather than 
this reflector because I am in digest mode and only get a batch of 
emails  once a day.  I am fortunate to still have this Power Mac 7500 
OS 9.1 so I can send out this email. I appologize for using this 
reflector but I am desperate to get it fixed so I can use the digital 
modes of ham radio.

Thanks,

Jerry WA0BFD
