   Many use the program spektrumisty MINI BOOT V3.0, which 
allows you to install a floppy boot with a nice font and a very 
interesting fact that is installed on nulevyyu track of the 
disk, that is, practically, does not take place on it. What is 
interesting: it has no buttons reread the directory when you 
change the disc. Yes and do not need it to him, because he 
controls the presence of disk in the drive and when it changes

brings a new directory. However, he has a
drawback: if you - the owner of Scorpion or another computer
turbo-mode, this option does not work. Well
no time to fire it all! Fix this in two ways. The first - to 
work only in "normal", and the second - Here it is!


   Take a floppy disk installed on the
It boot'om and with any disk
Dr. exit on the 13th sector of track zero (the second part, 
where you will see the name and the nickname of his boot'a 
author). The top of the search for the sequence: # C9, # DD, # 
E5, # C3, # 30, # 3D. Well, # C9 - this is the end of the 
previous procedure, and then comes the last routine of this 
boot'a: 


     ..............

     PUSH IX

     JP # 3D30



   Here's something to this routine and must make
the following changes:


     .............

     NOP

     NOP

     NOP

     PUSH IX

     JP # 3D2F



   That is, disk doctor you change
one sequence to another:

   Was: C9 DD E5 C3 30 3D

   Become: C9 00 00 00 DD E5 C3 2F 3D.

   It's okay that our protsedurka
longer, the routine, then the last! Now and in the turbo-mode 
boot is working fine!
