   You can get almost instant-on by turning on a fast boot switch which is   
   available in most BIOS. Fast boot eliminates a lot of the checking (such as a   
   RAM test) the regular boot does. Remember, for the old systems, the ROM was   
   written for just that    
   particular hardware. There was no need to try to identify all sorts of   
   different hard drives, USB devices, etc. The ROM knew exactly what was there   
   and only needed to start BASIC or an rudimentary menu. Modern systems then   
   have to load a very complex OS    
   from some device. When everything is in ROM, there's no need to do that.
