Hi guys,
 
I recently a lot of questions i know the answer of, so here they are:
 
   1)  Changing the seekrate of the floppy disc drives on a legal way:
 
             It's quite simple once you know:
             $440 word contains the seekrate this way:
 
             0     ->   6 ms
             1     ->  12 ms
             2     ->   2 ms
             3     ->   3 ms
 
   2) turn of the verify on writing:
 
             make $444 (word) zero.
 
   3) Adresses of 1) and 2) are garuanteed not to change when other re-
      leases of GEMDOS, XBIOS or BIOS come out. So one can use it! The
      adresses must be changed in Supervisormode!
 
   4) How to get Pexec to work:
 
      long Pexec(mode, ptr1, ptr2, ptr3)
      int mode;
      char *ptr1, *ptr2, *ptr;
 
      mode       function        description
 
        0        load and go     ptr1 = pathname to the program you want
                                        to run.
                                 ptr2 = Command tail (like the dialogbox
                                        when you invoke a .ttp file from
                                        the desktop).
                                 ptr3 = Environmentstring (only included
                                        for compatability with MS-DOS).
 
        3        just load       same pointers as above, you get the
                                 address of the basepage back.
 
        4        just go         ptr1 = address of basepage.
 
        5                        make a basepage and allocate free memory.
                                 Not everything you can expect is included
                                 however.
 
   5)  The standard formatter  makes an interleave of 0:
       1 2 3 4 5 6 7 8 9. It's quite easy to make your your own formatter:
       With help of the functions Protobt and Flopfmt you can do a lot!
       (if you don't know how just send me a message and i'll explain).
 
   6)  Atari uses a modified Wd 1772 controller from Western Digital. The
       modification lies in the steprates. (And also there's some malfunction
       in de read track command: for those of you who want to write a copier
       which copies all protected software: it can be done! :-) ).
 
   7)  I sent a message a while ago containing some stuff on MS-Write. (that's
       the name). I don't think it was a demo: Everything seems to work
       (according to my friend).

                      Which expressions ?
