Hello,

 

I picked up a Optiplex GX150 from a local university.  The system won't boot.  Get 1-1 POST beep and 3 green & 1 yellow LEDS on back.  Message on screen says "Press F1 to retry boot, F2 to enter setup".  Entered setup and there was a BIOS password.  Followed the instructions to get passed the BIOS password.  Couldn't find anything specific there to help.  The only thing in the system event log is a CMOS Checksum Error with munged up date/time stamp.  I read the diag leds wrong and tried flashing the BIOS from A07 to A11.  Still no help.  Will boot from diskette but won't w/o diskette.  Get above symptoms.  Anybody have any ideas what to try next?  TIA.
