   Yes, I remembered that your OS very impressively booted in about 2   
   seconds. AISI there are two parts to startup:   
      
   1. Firmware boot time   
   2. OS boot time   
      
   As the video shows, both of those were negligible on that old 8086. (And   
   it looked as though config.sys and autoexec.bat were empty so there was   
   nothing for the OS to do on startup.)   
      
   Today most PCs take some time in the firmware before an OS gets to start.   
      
   But typically the biggest drag on startup time is the OS. The most   
   common OS, Windows, can take many minutes while Windows gets its act   
   together. And the story doesn't end there. Even after my Windows PC has   
   presented a GUI it will be virtually unusable for some further period of   
   time because it is still hammering the disk.   
      
   Maybe the old days had some good after all. :-)
