Message-ID: <13679@chaph.usc.edu> Date: 15 Dec 90 07:12:13 GMT Sender: news@chaph.usc.edu Organization: University of Southern California, Los Angeles, CA Lines: 21 Nntp-Posting-Host: aludra.usc.edu We have a Leading Edge Model D2 Computer equipped with an Intel Above Board/2 Plus 8 with a Deico Electronics Super-VGA board using the Tseng Video Chips and the ET4000 controller. We also have a Toshiba IDE 105mb hard drive. What happens is it boots just fine with the cover off, but locks up with the cover on. We removed one of the grounding clips and it seems reduce the amount of lock ups. Is this safe and am I on the right track in removing the remainder of the grounding clips to the case in hopes of solving my bootup problem? My roomate tells me the new Toshiba hard drive is creating a grounding loop (whatever that is) with the video card. Can someone explain this strange problem? Sorry, but I am getting desperate since bootup lockouts ain't fun. I'm a software person, not hardware. ...dale ------------------------------------------------------------------------------ name: Dale C. Chun | * 2 + 2 = 5, for sufficiently large values of 2.
