Hab mir grad mal für meine MS-DOS-Sammlung ein paar Bootdisketten für Partition Magic 8.0 erstellt und eingelagert. Funktioniert problemlos auf allerlei Konfigurationen!
Wer weiß, wofür man's nochmal braucht:

Aha! Found it! I'd been looking for this. Recommended once by YouTube, and then lost.

… on GEM
… on DR-DOS
… on an 8086 PC emulator
… on a Raspberry Pi
… running as a second processor using a BBC Master 128 for I/O.
There's a follow-up re-hash video by @WiFiSheep that explains the tokenization problem with the CIRCLE statement.
Of the many people who have run #Elite on a Pi second processor, none seem to have thought about switching to the PDP-11 emulation and trying to run some early Unix. But seeing DR-DOS on a BBC Master is pretty wild.
@nina_kali_nina : nice read, writing that must have been a lot of work!
Besides MSDOS, we were running DRDOS (Digital Research) on a couple of PC's (PC AT's) in the physics reseach group (Delft university) where I worked at the time.
Microsoft did their very best to destroy that competitor, by preventing that Windows 3.1 would run on DRDOS (Andrew Schulman figured out why: [1]).
Right before I started working there, I had privately bought an Atari ST. It ran DR GEM on a relatively high-res (80x25 perfectly readable black chars on white background) monochrome screen with 71Hz refresh frequency (way better than flickering green or amber CGA-monitors), and more importantly (as a programmer): a flat memory space (68000 CPU @ 8Mhz, slightly faster than a Mac). No 64kB segments!
Frank Ostrowski's GFA BASIC (which had not much in common with MS BASIC) was a brilliant programming language (I enjoyed writing assembler routines for time-critical stuff, that could be easily called from GFA BASIC).
W.r.t. Intel CPU-based PC's, Borland was a game changer. While my girlfriend learned Turbo Pascal (to be followed up for also revolutionary Delphi for Windows), I learned C++ using Borland's compiler.
At work Charles Petzold's book "Programming Windows 3.1" (https://archive.org/details/programming-windows-31-3rd-ed) proved helpful (although writing an "Hello World" program was awkward) after we upgraded to Windows 3.1, and later Windows 3.11 for Workgroups - with a TCP/IP stack installed.
Anyway, thanks again for reviving my memories from way back when, and I wish you all the best for 2025!
#SvarDOS: DR-DOS is reborn as an open source operating system
https://www.theregister.com/AMP/2024/12/23/svardos_drdos_reborn/
Mein erstes Betriebssystem auf einem IBM-kompatiblen PC war übrigens DR DOS 3.41 - und ich bin dann auch bis DR DOS 6 dabei geblieben. MS DOS konnte mich nie wirklich überzeugen.
Nach DR DOS 6 stand für mich aber OS/2 im Fokus, und ich habe die weitere und verworrene Entwicklung von DR-DOS/OpenDOS 7.x unter Novell, Caldera, Lineo und DeviceLogics bzw. Udo Kuhnt (Enhanced DR-DOS) nicht mehr verfolgt.
Interessant war es für mich noch, DR DOS innerhalb von OS/2 zu verwenden, als virtuelle Maschine ("DOS von Diskette starten").
New binary release 20240914 of the EDR-DOS kernel is out. This release fixes a few boot and compatibility problems with original IBM-PC and with disks larger than 502 GiB.
I today released a new version of the EDR-DOS kernel and command interpreter.
We made progress in preventing the EDR kernel from accessing uninitialized partitions.
This is an interesting one: DR-DOS shipped with a FDISK program which initialzed partitions with a file system right away, without the user having to FORMAT it. But because of this, the DR-DOS kernel never implemented proper filesystem validation.
The whole thing falls apart when using the EDR kernel with Free FDISK and NOT formatting a partition. Curiously, the kernel could then access the non-existing filesystem. But not anymore...
You can get it at https://github.com/SvarDOS/edrdos/releases/tag/r20240821
A little update on my DRDOS kernel project: I managed to produce a single-file version of the kernel. It normally consists of DRBIO.SYS and DRDOS.SYS.
The name of the combined kernel is KERNEL.SYS and supports the FreeDOS load protocol (have to sort out a few minor bugs though). This means that it can be installed with the same SYS command as the FreeDOS kernel.

#DRDOS - Braucht das jemand von Euch? 5.0 ist nicht mehr ganz aktuell. Aber vielleicht kann man unkompliziert auf 7.0 updaten.
@ElectricWill @Seraphyn People like to do this, because Microsoft isn‘t trustworthy. It has been a shady company and it is still one. #halloweenpapers #USVsMicrosoft #evilempire #netscape #drdos #predatorybehavior #antitrust #linux #appleMacintosh
