If you want to create a boot disk which contains AmigaOS 2.0 or 2.1, the
procedure for doing so is the same as it is for AmigaOS 3.0 & 3.1, and
this means that you can use the "Creating the Amiga911 disk" tutorial for
these OS versions as well. In addition the main basics of how the
boot disk works is the same for both 2.x and 3.x, this means for example
that the same Startup-Sequence file is used, but it will be slightly
modified to suit each AmigaOS version.
You should also note the following:
1. It is not possible to include Poseidon,
JanoEditor, PFSSalv2 or SFSSalv on 2.x versions of the Amiga911 disk since they require AmigaOS
3.0 or higher. FileMaster3 can now be added to 2.1 projects since it
(partially) works with this OS version, take a look at this
page for more info.
2. On the 3.x version of the Amiga911 disk, MiniXpkGuide is used as
an alternative to MultiView (uses datatypes), but on the 2.x version it is
used as an alternative to AmigaGuide instead (uses amigaguide.library
directly). It is still called MultiView though, this is to make things
easier for stuff like the ToolsDaemon menu for example.
3. By default, AmigaOS 2.0 doesn't support PC formatted floppy
disks, but this functionality will however be included on the 2.0 Amiga911
disk. This is done by simply using mfm.device from the Workbench2.1 disk.
4. AmigaOS 2.1 uses the same method as 3.x for mounting devices,
this means seperate mount files for each device in Devs/DosDrivers/. But
AmigaOS 2.0 on the other hand, uses as standard the 1.x method with one single
file called MountList in Devs/ which contains all mount entries.
Regardless of this, the 2.0 version of the Amiga911 disk will now contain
the same mount files as OS2.1, this is because a third-party alternative
to the original Mount command is used.
5. The 2.0 Amiga911 disk will not include the standard version
37.27 of asl.library, instead it will use the 38.36 version which is
supplied with the TurboText distribution. This is because it's required by
TurboText, but also because it is so much better than the old version. The
2.0 disk will now also include RTPatch, which can force programs to use
reqtools.library instead of asl.library, this is mainly done to solve the
conflict with the Redit text editor.
6. Of the different 2.0 variants of the system floppy, only
Workbench 2.05 has been tested for creating Amiga911 disks, but I'm
convinced that Workbench 2.04 should work fine as well. I am not so sure
about the Workbench 2.0 disk though (only supplied with the earliest A3000
