Week #42 of 1998, we made 2 celerons run on a dual card. 
Week 1998-10-12--1998-10-18; 
   Monday: Bought dualcard (Gigabyte GA6BXD), we already got 2 celeron 266Mhz.
  Tuesday: Started to drill by hand. Drill broke and stuck in first celeron. Sad.
Wednesday: Bought new drills, got the stuck drill out.
 Thursday: Machinedrilled the first celeron again.
           Thanks to ETF at LTH for fine boarddrill with speedalteration.
           Verified operation still OK in 400Mhz.
   Friday: Drilled 2nd; and succeded making BIOS detect dual celeron configuration. SUCCESS!
   Sunday: NT RUNS FINE with mps-kernel and detects 2 processors.
           We did it!

   After this we did it again with 2 other celerons. One of these unfortunately stopped
   without reason(?) so after doing a fifth we have had 80% successrate and a lot of fun.
   And we now have 2 dual celeron systems! One running Linux and one running NT.
   The fifth processor was handdrilled. It felt most comfortable, actually - even after the first break.
   Notable is that the "good" drills were NOT hardmetal drills. 
   
   Note: We had only 64MB RAM during the tests. Final configuration will be about 256MB.
NT running fine with halmps.dll and ntkrnlmp.exe
