This is the working source code from OSS, Inc. for the Atari DOS 2.5 system software. We deeply thank:\\

!!How to build Atari DOS 2.5 from OSS
First, please read these two text files and have 48 KB RAM in your Atari:
* [README.txt] ; Text file, which introduces all files needed to create a running DOS 2.5 disk.
* [Building_the_OSS_DOS_2.5_sources_on_the_Atari.txt] ; This is the recipe on how to do it.\\
\\
Then, please go on with these disk images:\\
* [builddos.atr] ; DOS II 2.0s disk image with all files needed to create DOS 2.5 with the below given files.\\
* [empty.atr] ; Blank DOS II 2.0s formatted disk-image to work with the above files.\\
* [mac65102.car] ; MAC/65 Version 1.02 cartridge to read in the above MAC/65-files. Many thanks to AtariGeezer from AtariAge for giving us that rare to find 034M-cartridge from OSS.\\
\\
The above image builddos.atr needs the following source files. Here we can go on in two ways:\\
\\
a) the easy one:\\
\\
If you have booted with the above disk image, please insert either the dossrc_a-w.atr image or the dossrc-w.atr image in drive 2 (D2:):\\
* [dossrc_a-w.atr] ; Working source code for building the FMS (File Management System -> DOS.SYS-file) on an SD ATR-image with MAC/65-files.
* [dossrc_b-w.atr] ; Working source code for building the DUP.SYS-file on an SD ATR-image with MAC/65-files.
* [dossrc-w.atr] ; Same as the both images above, but on just a single DD ATR-image with DOS 2.0D.
\\
Then type:\\
LOAD #D2:FMS.M65\\
ASM\\
You should receive the following figure:
[{Image src='DOS.jpg' width=408 height=230 }]
Successful assembled source code for the creation of DOS.SYS\\
\\
Then insert either the dossrc_b-w.atr image or leave the dossrc-w.atr image in drive 2 (D2:):\\
\\
Then type:\\
LOAD #D2:DUP.M65\\
ASM\\
You should receive the following figure:
[{Image src='DUP.jpg' width=404 height=217 }]
Successful assembled source code for the creation of DUP.SYS\\
\\
Congratulations! You have created the object code for building DOS 2.5. :-)))\\
On how to go on further, please read the recipe above.\\
\\
b) the hard one:\\
\\
The way is the same as in example a), except, that the below given original source files:\\
* [dossrc_a.atr] ; Original source code for building the FMS (File Management System -> DOS.SYS-file) on an SD ATR-image with MAC/65-files.
* [dossrc_b.atr] ; Original source code for building the DUP.SYS-file on an SD ATR-image with MAC/65-files.
* [dossrc.atr] ; Same as the both images above, but on just a single DD ATR-image with DOS 2.0D.
\\
have to be patched to actually work. Please read the recipe above on how to this.
