 </p>
-<ul>
- <li>
-  Atari ST and STE have only been shipped with a 68000 CPU, so for best
-  compatibility with old programs, choose this CPU type.
- </li>
- <li>
-  Atari TT and Falcon computers were using the 68030 CPU, so you should switch
-  use 68EC030+FPU (Hatari doesn't support 030 with MMU and some programs don't
-  work with 68020 so this is the best choice).
- </li>
- <li>
-  TOS 1.0x only works with 68000, while TOS 3.0x and 4.0x work only with a CPU
-  &gt;= 68020.
- </li>
- <li>
-  68010 and 68040 have never been used in official Atari computers, so don't
-  use these CPU types unless you've got some good reasons.
- </li>
-</ul>
-
 <p>
- Beside the CPU type, you can also choose the machine type to emulate.
- The ST was the very first 16/32-bit computer from Atari. Most older games
- and demos require an ST. The STE was introduced some years later and had
- some more advanced hardware features. There are not that many demos or
- games that really require an STE but since most normal ST games/demos also

  <br />
  TT and Falcon are more advanced, but they are not as compatible to the ST as
  the STE was. Therefore many old games and demos do not work with these machine
  types anymore. There were only very few programs that were made for the TT
  exclusively, while there were some interesting games and demos specially made
  for the Falcon.
- <em>Note:</em> TT and Falcon emulation are incomplete. They may not work
- very well.
+ <br />
+ <em>Note:</em> Falcon and especially TT emulation are still considered as
+ experimental and incomplete.
+ Quite a bunch of programs do not work very well yet.
 </p>
 <p>
  For STE emulation a STE compatible TOS image, e.q. version 1.06, 1.62 or
  2.x, is strongly recommended. For TT emulation you need TOS 3.0x and for Falcon
  emulation you need TOS 4.0x. EmuTOS can be used on all machine types.
 </p>

 <p>
- Select the CPU clock you want to use. 8Mhz is ST standard and the most
- compatible. Use 16MHz for Mega STE and Falcon emulation.
+ The CPU type option can be used to select the level of the central processing
+ unit. If you are not sure what to use, simply select 68000 for ST and STE
+ machines and 68030 for TT and Falcon emulation, since this were the original
+ configurations used in the Atari computers. In case you want to vary
+ the CPU type, you have got to be aware of some constraints:
+</p>
+<ul>
+ <li>
+  Atari ST and STE have only been shipped with a 68000 CPU, so for best
+  compatibility with old programs, you should choose this CPU type.
+ </li>
+ <li>
+  If you are going to use TOS 1.0x, you also have to select the 68000 CPU,
+  since these TOS versions are not aware of the higher CPU levels yet.
+  If you want to use a higher CPU level with the ST or STE machine type,
+  you've got to use TOS 2.0x instead.
+ </li>
+ <li>
+  Atari TT and Falcon computers were using the 68030 CPU, so you should select
+  the 68030 CPU type for these machines.
+ </li>
+ <li>

+  Hatari, and is currently also considered as experimental, so do not use
+  this option unless you know what you are doing.
+ </li>
+</ul>
+
+<p>
+ The CPU clock option can be used to select the frequency that is used
+ to clock the CPU. 8 Mhz is the standard for ST and STE and the most
+ compatible frequency for old software.
+ Use 16 MHz for Mega STE and Falcon emulation.
  The CPU in the TT was clocked with 32 MHz.

+ works better.
+</p>
+<p>
+ With the &quot;Boot faster&quot; option, Hatari patches the TOS ROM and some
+ system variables, to speed up the boot process of the emulated system, e.g.
+ by simulating a warm reset. This is a convenient option, but some very few old
+ programs rely on an unmodified boot process, so in rare cases this option has
+ to be switched off to get those programs running.
+</p>
+<p>
+ The &quot;Prefetch mode&quot; option is used to enable the emulation of 68k
+ address errors and the so-called CPU prefetch buffer. This is needed for best
+ compatibility, but it slows down emulation a little bit so you can disable it
+ if you don't need it and if you have a slow host system.
+</p>
+<p>
+ The &quot;Cycle exact&quot;, the &quot;MMU emulation&quot; and
+ &quot;24-bit addressing&quot; option are only available in the

+<p>
+ The FPU settings are also only available with the &quot;WinUAE&quot; builds
