How to make a RESET
-------------------

Here is the official routine supported by Commodore:
                             ^^^^^^^^^^^^^^^^^^^^^^


  INCLUDE "exec/types.i"
  INCLUDE "exec/libraries.i"

;  csect text                  ; in lattice ASM
;  section text,code           ; in Devpac/Argasm

  xdef  _ColdReboot
  xref  _LVOSupervisor

EXECBASE        equ 4
ROMEND          equ $01000000
SIZE_OFFSET     equ -$14

KICK_V36        equ 36
V36_ColdReboot  equ -726


_ColdReboot:
      move.l EXECBASE,a6
      cmp.w  #KICK_V36,LIB_VERSION(a6)   ;which Version of Exec ?
      blt.s  .old_kick                   ;old one -> goto old_kick

      jmp    V36_ColdReboot(a6)          ;else use Exec-Function

.old_kick:
      lea    .Reset_Code(pc),a5
      jsr    _LVOSupervisor(a6)          ;get Supervisor-status
      ;never reaching this point

      cnop 0,4                             ;very important
.Reset_Code:
      lea    ROMEND,a0                   ;Calc Entrypoint
      sub.l  SIZE_OFFSET(a0),a0
      move.l 4(a0),a0
      subq.l #2,a0
      reset                              ;Reset peripherie
      jmp    (a0)                        ;done
                     ; <reset> and <jmp> in the same LONGWORD !!!!

Trackloaders
------------

Use CIA timers! DON'T use processor timing. If you use processor timing you
will MESS UP the diskdrives in accelerated Amigas.

Use AddICRVector to allocate your timers, don't hit $bfxxxx
addresses!!!

On second thoughts. DON'T use trackloaders! Use Dos...
